1.1 Features

The

Series 505



High Speed Counter (HSC) module (PPX:505-7002)

provides two independent high-speed counter channels.

Each channel has the following features.



Four counter modes:



Pulse counter



Quadrature counter modes: 1X, 2X, 4X



A 10 kHz count rate with a minimum pulse width of 25

s.



Four inputs:



two count inputs

reset

inhibit

T

wo field outputs, each controlled by a separate programmable preset.



LED indicators display the status of the A and B count inputs, and of

Y1 and Y2 outputs.

All inputs may be sinking or sourcing (with external 24 VDC power

supply).

The HSC module operates asynchronously from the controller scan. Y

ou

can program the controller to monitor the HSC and/or to provide high-level

control of the HSC’

s operation. T

o support these functions, the HSC

provides reset, inhibit, output and counter status to the controller and

accepts reset and inhibit commands, and preset values from the controller

.

! The

HSC module controls its four outputs. If the controller switches from the Run

mode to the Program mode, the HSC continues to function as programmed, and

outputs may be activated by the HSC. This means that if you switch the controller

to Program mode, any devices controlled by the four outputs of the HSC will

continue to operate as programmed.

1.2 Inputs

The

HSC module has two independent channels. Each channel has four

inputs.



Reset



Inhibit

T

wo counter inputs

Each input may be used as either sinking or sourcing (with external 5–24

VDC power supply). The input signals are connected to the field wiring

terminal block on the front bezel.

Counter Inputsą

Each channel has two counter inputs — Input A and

Input B.

Reset

Current flow through the reset input sets the channel’

s counter to

zero. The counter will be held at zero until the reset input becomes

inactive.

Inhibitą

Current flow through the inhibit input inhibits the channel from

counting. The counter holds at the last value and does not change until the

inhibit input becomes inactive.

NOTE:

When in the pulse counter mode, if the A or B input is in a

different state at the beginning and end of an inhibit signal, the count will

change according to the normal counting logic. If both A and B inputs are

in different states, the change may be as much as two counts.

NOTE:

There are also software reset and inhibit functions. See Section 3.

1.5 Counting Modes

1.5.1

Pulse

Counter

Each channel has two inputs, A and B. In the pulse counter mode, counting

Mode

occurs on the rising or falling edge of the incoming pulses. The relationship

of the states of these two inputs determines the direction of the count. See

ypical devices for counting are high-speed static switches or

Quadrature

Mode

For quadrature mode, each channel counts according to rising and/or



falling edges. T

ypical devices for quadrature inputs are optical encoders.

Different quadrature modes are selected based on the resolution required

by the application and the encoder used.

The module counts on the edges of the A input pulses.



When input A leads input B, the HSC counts up on each rising edge of

input A.



When input B leads input A, the HSC counts down on the falling edge

of input A.

the probability of damage to these devices when you are handling a

Both the module and the person handling the module should be at the

In some installations when both the HSC and TI505-49XX series of relay

modules are used, false counts may be induced when switching high

voltage in the relay module, (voltage > 40 V

internal arcing of the relay contacts.

If you encounter this problem, place a snubber consisting of a 47 ohm 1/4

watt resistor and a 0.022

on the terminal block. Snubbers were not included in the relay modules in



Module outputs will turn on during this procedure.

1.

Using a programming device, force all presets to 0.

2.

Reset both counters through the reset signals from your application.

Using the default configuration, the outputs should turn on.

3.

Using your programming device, force the presets to any number

greater than 0.

The outputs should turn off.



Before resuming normal operation, clear any words that you have

forced. Otherwise, these words remain forced during operation and could

yield unexpected results.

If you used the setup word to configure the module, then the output follows

your configuration.

5.1 Sprayer Example

5.1.1

Description A

reversible DC motor drives a paint sprayer up and down a vertical

assembly

. A quadrature encoder on the drive shaft senses the direction and

relative position of the sprayer

. Channel 1 of the HSC will be used to

enable the sprayer during a pre-defined section of travel. (See Figure 5-1.)

The encoder resolution is 500 cycles per revolution. One shaft revolution

equals 1 inch of sprayer travel. When encoder signal A leads, the direction

of travel is up.

5.2 Flow Rate Example

5.2.1

Description A

flow meter outputs 200 pulses per gallon. The program requires

calculation of flow rate in gallons per minute (GPM).

5.2.2

Solution

Configure the HSC as WX9–WX1

1, WY12–WY16. Attach channel 1 to the

flow meter

. The HSC accumulates flow meter pulses for the duration of a

1-second fast timer

. In the controller

, accumulated pulses are scaled to

GPM by the following calculation (using the controller memory locations).

Equation: GPM = Pulses per Sec 60 ?200

Program Locations: (V23,V24) = (WX10) (V20) ?(V19)

Following each calculation, reset the HSC, restart the T

imer

, and perform

a new calculation 1 second later

5.3 Tank Filling Example

5.3.1

Description The

HSC module measures the volume of liquid and control the filling

valve. (See Figure 5-6.) A flow meter

, generating 200 pulses per gallon, is

connected to the HSC channel 2, input A. Output 2 controls the filling

valve. In this example, the HSC operates in the pulse counter mode.



Solution

A count of 100,000 pulses is required to fill the tank to 500 gallons. As this

would overflow the HSC, the following RLL is used to count 10 sets of

10,000 pulses before closing the filling valve. In this program, output 1 is

used to indicate 10,000 pulses. Since the HSC runs asynchronous to the

PLC, the program accumulates overcounts for each loop and adjusts the

final loop to reach the exact count. The program utilizes the fact that the

HSC WX’

s are read before the WY’

s are written in an I/O cycle.

Several V memory locations are used in the program, their initial values

are:

V200 = 10,000 =

channel 2, preset 1

V201 = 30,000 =

channel 2, preset 2 initial value

V100 = 0

(overcounts will be accumulated here)
