1.1 Overview of the programming workshop

( § 1. )

( § 1.1.1 )

At a Glance

Subject of this Chapter

This chapter provides an overview of the programming workshop

What's in this Chapter?

This chapter contains the following topics:

Overview of the Programming Workshop( § 1.1.1 )

Creating or Modifying the Configuration of an Application( § 1.1.2 )

1.1.1 Overview of the Programming Workshop

( § 1.1 )

( § 1.1.2 )

Languages Used

The controller offers 1 programming language:

FBD language: Function Block Diagram

This language use:

Predefined function blocks:

Timers

em4 soft Online Help

Counters

Specific functions:

Time management

Character string

Communication, etc.

FBD mode

FBD mode allows graphic programming based on the use of predefined function blocks.

It offers a large range of basic functions: timer, counter, logic, etc.

Example of a program in FBD language:

Connection Types

There are several connection types: bit, analog (integer), SFC( § 1.4.2.9.1 ) (Grafcet).

Bit: (see 1 in the above drawing)

Symbolized by a single black line and a black incoming or outgoing arrow. This connection can take

the values 0 or 1.

Analog or integer: (see 2 in the above drawing)

Symbolized by a double black line and a black incoming or outgoing arrow on a green background.

This connection is an integer with a value between -32768 and +32767.

Operating Modes

There are several operating modes for the programming workshop:

Edit mode

Edit mode is used to construct programs in FBD mode, which corresponds to the development of the

application.

In order to simplify the wiring, note that:

- Non-connected enable inputs are by default "enabled", see the Display blocks in the example.

- Non-connected inputs in Logic blocks are not taken into account, see the AND, BOOLEAN blocks in

the example.

Simulation mode

In simulation mode the program is executed offline directly in the programming workshop (simulated

on the PC).

In this mode, each action on the chart (changing the state of an input, output forcing) updates the

simulation windows.

Debugging mode

In Debugging mode, the program is executed on the controller, the programming workshop is

connected to the controller (PC  controller connection).

em4 soft Online Help

The different windows are updated cyclically.

In simulation and monitoring modes, it is possible to:

View the output states and function block parameters of the program corresponding to the wiring sheet

in the supervision window.

Force the inputs/outputs to test program behavior under specific conditions.

Note: A non-connected BIT input takes the value 0.

A non-connected ANALOG input takes the value 0000.

1.2.7 How to Debug an Application Without Loading it onto the Controller: Simulation

( § 1.2.6

)

( § 1.2.8 )

Introduction

Before loading a program onto a controller, it is possible to simulate execution using the programming

workshop.

In simulation mode, for each action that the user performs, there is a corresponding simulation, whose

results are displayed in the Front Panel( § 1.2.7 ), Edit( § 1.2.7 ) and Supervision( § 1.2.7 ) windows (not

available in this version).

Access

After creating a diagram in the wiring sheet, click on the icon in the controller bar to access

simulation mode.

Front Panel Window

The Front Panel window is automatically available as soon as Simulation mode is launched. The keys

can be used like real keys. Each click allows use of any function that could be accessed from the front

panel of a real controller. The result of these actions is then displayed in the simulation on the LCD

screen.

In simulation on the "Front Panel" window, click on OK with the mouse + Escape on the keypad and

release simultaneously to replace the display on the DISPLAY screen with the menu display.

The Edit (Simulation Mode) and Supervision Windows (not available in this version)

The Edit (simulation mode) and Supervision windows (not available in this version) accessible via the

menu : Window are illustrated by an FBD example in the following illustration:

The table below lists the different elements:

em4 soft Online Help

Number

Description

Simulation/debugging

The simulation/debugging window is used to modify simulation rates or to simulate certain events affecting the

controller. This highlights all the transient problems, in particular upon launching the application and when power

is restored following a power failure.

The Refresh period corresponds to the frequency with which the output and parameter values are updated in

the open application windows.

The Number of cycles integer is the number of cycles executed during a refresh period.

Edit window

The edit window shows the program on a wiring sheet and is used to view the various states and numerical

values being used.

The states and values may be temporarily modified or permanently forced by double-clicking or right-clicking.

The table below lists the different elements:

Number

Description

The date and time displayed show the simulation time. They depend on the number of cycles executed for each

refresh period and on the basic cycle time( § 1.6.1.1 ).

The Set Clock button is used to advance or put back the date and time (confirm by clicking on the Write to the

controller button).

The Pause button is used to stop or restart simulation.

The Next event button is used to advance to the next Time Prog event.

This button can only be used if events have been defined using a Time Prog function.

Function Blocks Window

The Function Blocks window, accessible using the Summary Table button in the

Display/Simulation Bar/Debugging window, summarizes for each function:

The symbol

The type of function

The block number

The parameters (for the relevant functions)

Whether the Save on power failure( § 1.2.20 ) option has been selected

The current value (for relevant functions)

Whether it is possible to modify function parameters from the controller front panel

The comment entered by the user

em4 soft Online Help

It also provides access to the parameters for each function by double-clicking on the relevant line.

1.2.8 How to Monitor and Modify an Application Running on the Controller: Debugging

( § 1.2.7 )

( § 1.2.9 )

Description

To remotely monitor or modify the behavior of a program running on a controller, the user

can use the debugging function. This debugging allows the user:

To temporarily modify or permanently force:

Any of the function outputs

The majority of the function parameters

As well as all the buttons on the controller front panel

Then to display periodically the execution of the program, observing:

The values of the controller I/O and its extensions

The block outputs

The current state of the parameters and the displays of the controller front panel

when online

Switch to Controller and programming workshop debugging Mode

The programmer can only switch to this mode if the controller:

contains a program in which parameter modification is not read/write protected by a

password

contains a program in which parameter modification is read/write protected and where

the programmer knows the password

The HMI checks whether a password protects the program and parameters or the

controller parameters. If this is the case, the HMI displays the Password dialog window.

The chart in the Edit window must be consistent with the program in the controller. The

HMI starts the "Compare the controller data with the program" function. If a difference is

found, the HMI returns to edit mode.

Following these checks, simply click on the button in the toolbar to switch to

debugging mode. After this action, the following is displayed:

Either, in the controller toolbar, a set of icons that can be used to start and stop

application execution in the controller and the frequency at which output and

parameter values are updated in the open application windows.

Or in a "Simulation/Debugging" window

This shows:

The state of the controller I/O and any extensions

The program states

The I/O and parameters (including output parameters) of the FBD function blocks

The current value of each link is displayed near the function block output. Debugging

mode is independent of the "Controller On/Off" function. If the controller is off, only

modifications to the parameters and the inputs on the buttons of the controller front panel

are displayed.

Note: The Debugging mode cannot be considered as a dependable debugging

method, because on the online controller that switches to debugging mode, the basic

cycle time( § 1.6.1.1 ) is extended by the communication times between the PC and

the controller and possible permanent forcing times applied to the application. No

guarantee can be given concerning the actual duration of cycle times during this

operating mode. Moreover, during this operating mode, the WATCHDOG action( §

1.6.1.1 ) linked to the application is deactivated.

In addition, when applications without permanent forcing are executed, the application

may run on the controller for a time that is much shorter than the refresh period of the

PC debugging windows. It is not therefore possible to observe actions on the controller

that are executed at less than twice the debugging screens refresh period (Shannon

em4 soft Online Help

sampling rule).

Front Panel Window

This window allows you to click with the mouse on any key on the controller front panel

which is depicted in the window. The keys in the Front Panel window can be used like

keys on the actual controller front panel. Any function which can be accessed from the

front panel of an actual controller can be applied to the actual controller with a single

mouse click. The result of these actions is then displayed in the copy on the LCD screen.

Debugging Control

The commands that can be used to control debugging are:

The Stop button on the controller bar

The On button

The time between 2 displays of controller data on the screen (modifiable value)

The refresh frequency of the Debugging bar corresponds to the frequency at which the

output and parameter values are updated in the application windows that are open

during debugging mode: decreasing this frequency, and consequently the refresh period,

reduces the workload of the programming workshop that monopolizes the PC to the

detriment of other system or user programs.

Note: Modification of the refresh frequency is essential in order to limit the time allotted

to the programming workshop by the Windows system. This is because in older

Windows systems or small PC configurations, the load used by the programming

workshop in debugging mode significantly slows down open applications running in

parallel or system operations.

1.2.16 How to Check an Application Using the Programming Workshop

( § 1.2.15 )

( § 1.2.17 )

Overview

The check command launches program compilation.

Two types of check can be used for an application:

The first checks consistency of the diagrams

The second checks the performance of the user application, i.e. the compatibility of:

The memory usage

The user application cycle times

The memory capacities

em4 soft Online Help

The controller execution speed

Diagram Consistency Check

Compilation is carried out automatically in the following cases:

Switching from Edit mode to Simulation/Debugging mode

Transferring the program to the controller

Consistency of FBDs: This only concerns SFC network wiring errors. FBD networks

always behave consistently: inconsistent wiring is impossible, and if an input is not

hard-wired it is set to a constant value that does not affect execution of the function or

makes it passive. See the online help for each function.

User Application Performance Check

This appears in the Compilation Result window in the following cases:

Activation of the menu/Controller/Check the program

Switching from Edit mode to Simulation/Debugging mode

Transferring the program to the controller

These performance checks are useful on a simulator as they can be used to obtain a

controller that meets the requirements of the proposed application, once the application

has been created and simulation-tested.

Note: When optional, the window is only displayed when the controller capacities

(memory space and execution speed) are too low in relation to the user program

being checked.

Note: The compilation time for programs that use more than 128 FBDs or SFCs and

numerous loops, may exceed several minutes.

User Application Memory Size Check

The program compiler calculates the volumes used in the different controller memory

zones:

Parameters.

Bit data (block outputs):

Other data (function block outputs).

Program zone: the number of bytes corresponding to all program function blocks

displayed in FBD, and all functions that can be programmed on the selected

controller type (independently of the programming workshop).

In the event of capacity overflow, the window is still displayed and the overflow zones

are shown in red.

The zones shown in blue alert the user to the fact that the size of the application

memory zone concerned is very close to the maximum capacity of the corresponding

memory zone on the selected controller.

User Application Estimated Duration Check

The compiler also calculates the estimated duration of the program by adding together

the individual cycle times of each function used.

The user application runs periodically and its execution period is defined by the user in

the basic cycle( § 1.6.1.1 ) time.

This time corresponds to the minimum sampling period of the controller inputs

(exception: High-speed counter function) and the minimum time for modifying the

output values. The application response time is therefore twice the duration of this

period.

Note: (Take account of the fact that the compiler arranges the functions of an FBD

diagram from inputs to outputs, cutting the loops as close as possible to the outputs

and SFC diagrams from each INIT STEP or RESET INIT, to the downstream steps. )

Not all automation applications need blocking on overrun of the target application

execution period. Indeed, in some cases such blocking is dangerous.

Consequently, the user may decide whether or not to use a WATCHDOG( § 1.6.1.1 )

that will generate an alarm or error if the application is in ON mode on the controller,

when the application cycle time, added to the duration of the processing specific to

em4 soft Online Help

operation of the controller and any extensions, exceeds the duration of the selected

period.

A WATCHDOG warning may be returned to an FBD program to enable activation of a

retrieval sequence in the application. This is done using the controller status( §

1.4.2.6.11 ) function.

Note: All functions have a defined maximum cycle time, with one exception in FBD:

The cycle time of the TIME PROG function may vary from 1 to 51 depending on the

number of events used.

To determine the duration of the program execution period, programmers must:

Take into account the estimated duration in the compilation results table.

Carefully read and apply the recommendations written in the online help file:

available duration for the program.

To guarantee a constant program cycle time, you must also carry out appropriate tests

on the controller to verify that alarm or error 505 does not appear.

Duration of Processing Specific to Operation of the Controller and any Extensions

In addition to the processing time for the function blocks contained in the application

program, there are a number of additional processing operations during an execution

period which can easily be defined (as long as fixed) and are therefore taken into

account when calculating the time available for executing the application on each

period (compilation result).

But there are others, which can be either occasional or hard to quantify or account for.

Episodic processes:

Clock management: switch between summer and winter time.

Compensation for clock drift once a week, every Sunday at 1 o'clock in the morning.

The WATCHDOG is always ineffective while one of these operations takes place.

Note: If the application presents no danger to people or equipment in the event of an

increase in the cycle time, simply disable the WATCHDOG( § 1.6.1.1 ). Otherwise,

you must check the maximum execution period.

Note: Modifying parameters using other commands (PARAMETERS, etc.) increases

the application execution period by a variable time. The WATCHDOG is always

ineffective in this controller operating mode (Controller status( § 1.4.2.6.11 )).

Note: In the same way, the display of various data (text, data, hour, date) by active

functions, on the controller LCD display increases the application cycle time by a

variable duration. This duration depends on the type of data to be displayed and, for

the FBD, on the number of DISPLAYS simultaneously active.

Note: In Debugging mode, the cycle times are increased by the communication times

between the PC and the controller. No guarantee can be given concerning the actual

cycle times during this operating mode. The WATCHDOG is always ineffective in this

controller operating mode (Controller status( § 1.4.2.6.11 )).

Maximum Application Execution Period on the Controller Check

Given the problems of accurately estimating the user application cycle time and that of

certain processing operations specific to controller operation, in which increasing the

application execution period may present a danger to people or equipment, you must

perform the relevant tests on the controller to make sure that alarm 505 (cycle overflow)

does not appear, in order to guarantee the maximum cycle time of your program. See

WATCHDOG( § 1.6.1.1 ).

1.2.20 How the Controller Behaves in the Event of Power Failure

( § 1.2.19 )

( § 1.2.21 )

Power Failure

A power failure causes the following behavior:

The application is blocked, the controller LCD display freezes, and the buttons stop

working and all controller outputs are deactivated..

em4 soft Online Help

The programming software displays the following message: The target peripheral is

not reacting. Check the connection.

All communication stops

The date and time continue to increment during the power failure on controllers

equipped with a clock (battery powered).

Restart Following a Power Failure

The controller checks all its extensions are operating normally, then returns the data

saved on the power failure, and restarts the application execution with a specific

initialization sequence for power return.

This sequence initializes all function inputs and outputs, except the outputs of the

functions protected by a checked Save on power failure parameter.

In this case, these outputs are not reset, and therefore retain the value they had at the

time of the power failure.

To find out which function outputs are protected on power failure, consult the function

em4 soft Online Help

The quartz that controls the controller's real-time clock has a variable monthly drift

depending on the environmental conditions in which the controller is used.

The maximum value for this drift is approximately one minute per month.

To estimate this drift, observe the drift on the controller clock compared to a standard

reference clock for a few weeks or more.

Example:

If you wish to compensate this drift, you can, for example, make a -15 second

correction per week to compensate for a + 60 second drift per month. This

contains.

This function bar is divided into four parts:

 All the manufacturer tabs that contain all the application-specific functions and the standard

functions available with the workshop. These tabs are situated to the left of the function bar.

 the SPE function tab that contains all the application-specific functions for a given user.

 The MACRO function tab that contains all the Macros archived by the workshop user.

 All the customizable tabs that contain, by type defined by the user, the standard functions, the

application-specific functions and the archived macros.These tabs are situated to the right of the

function bar.

The standard or application-specific functions and Macros that are incompatible with the controller's

choice are shown with dark grey shading.

Filtered Discrete-Type Input

A filter can be selected from the Parameters window. Behind the Discrete input, a

filter is added to reduce or even eliminate disturbances.

A Discrete input is filtered using a constant level detection algorithm (1 or 0) on the

"sensor" signal, measured over a certain time frame. If the signal is stable throughout

the entire detection period, the output of the symbol from the filtered Discrete input

takes the value of the measured signal. Otherwise it remains unchanged.

The filtered Discrete inputs can be arranged at any controller input.

The value of the parameter (between 1 and 255) entered in the Parameters window

may be used to define the minimum time during which the signal must be stable. This

value is a multiple of the duration of the basic cycle( § 1.6.1.1 ) of the controller.

Etat de l'entrée

It is also possible to change the input state:

NO: normally open

NC: normally closed

Simulation and Debugging Modes

In Simulation or Debugging modes it is possible to force the digital inputs. In this case,

the input symbol is displayed as shown in the above table.

1.4.2.1.2 Analog voltage Input

( § 1.4.2.1.1

)

( § 1.4.2.1.3 )

Overview

The Voltage analog type input is available on all types of controller supplied with a DC

voltage.

The Voltage analog input voltage is converted into a numerical integer value by a 12-

bit analog to digital converter. The integer value of the output is between 0 and 4095.

Analog inputs can only be arranged on the inputs between I5 and IG.

Access

The Voltage analog input function is accessible from the IN/OUT window.

Parameter

By default, this voltage varies between 0 and 10V DC.

The type of electrical connection at the input can be configured in the Parameters

window:

0 - 10 V

0 - 30 V or potentiometer, selected if the input is connected to a potentiometric

device with a power supply between 0 Volts and the controller supply voltage

Types of Analog Input

Filtered Analog Input

A filter can be selected from the Parameters window.

Behind the analog input, a low pass filter is added. This function is available on all the

types of controllers supplied with a DC voltage.

The Analog input voltage is converted into a digital integer value by a 12-bit

analog/digital converter. The whole output value is between 0 and 4095.

The Analog inputs can only be placed on the inputs numbered from I5 to IG.

A low pass filter restores the entire input signal (frequency, amplitude and phase-

shift), whose frequency is considerable lower, to a typical filter frequency, called a cut-

off frequency. When the frequency of the input signal nears the cut-off frequency,

the output signal, of the same frequency, becomes increasingly lower and phase-

shifted. When the frequency of the input signal is equal to the cut-off frequency, the

output signal is lowered by around 30%, and phase-shifted by 45º. For a frequency

above and rising from the cut-off frequency, the reduction becomes greater (until it

reaches total elimination) and the phase-shifting approaches 90º.

The Parameters window is used to define:

The input voltage. By default, this voltage varies between 0 and 10Vdc. The

potentiometer is chosen if the input is connected to a potentiometer device

powered between 0 volts and the voltage of the controller power supply.

The cut-off frequency of the low pass filter (between 0.06 and 88.25 Hz)

em4 soft Online Help

CAUTION

The potentiometer option is selected if the input is connected to a

potentiometric device supplied between 0 Volts and the tester

supply voltage.

Whenever a modification is made to the basic cycle time, you must check

or modify the cut-off frequency

Failure to follow these instructions can result in injury or

equipment damage.

Scaling

A scale can be selected from the Parameters window.

For example here with a sensor from -20°C to + 60°C in 1/10ths of a °C.

Simulation and Debugging Modes

In Simulation or Debugging modes it is possible to force (between 0 and 4095 ) the

output of the analog inputs.

Delay in Availability of Measurements

The availability of analog input measurements is delayed by a few ms in the following

situations:

Power return following a power cut

Variation between 0 and full scale
