Completed Screens for Example (Guided Setup screens)

Ethernet

ENET1

This Ethernet Port can connect 100 Mbs between the controller and external devices.

Ethernet communication supports NTCIP and ECPIP protocols. Settings for these two protocols are

under System Protocol in the center of this screen. You configure Ethernet UDP Port for NTCIP in

System Protocol, NTCIP. The UDP port for ECPIP is fixed at 2101.

Note: Contact your Internet Protocol (IP) specialist to determine the correct setting for each of

the programmable parameters defined below.

Parameter Description

Address (0-255)

A unique address used by the Ethernet interface. The format follows the

Transmission Control Protocol/internet Protocol (TCP/IP) standard dot notation.

When used, the address must be assigned from the same subnet as the other

network devices with which it may communicate, such as a system controller or

File Transfer Protocol (FTP) server. If the controller is connected to an IP router,

the address must be valid for that router.

Net Mask (0-255)

The Net Mask must be the same as the other devices on the IP subnet to which

the controller is attached (when an Ethernet interface is being used).

This configures the ethernet port ENET2.

Parameter Description

Address (0-255)

A unique address used by the Ethernet interface. The format follows the

Transmission Control Protocol/internet Protocol (TCP/IP) standard dot notation.

When used, the address must be assigned from the same subnet as the other

network devices with which it may communicate, such as a system controller or

File Transfer Protocol (FTP) server. If the controller is connected to an IP router,

the address must be valid for that router.

Gateway (0-255)

The default IP address must be that of the Ethernet interface which is on

the same subnet as this controller. This gateway address will be used for

transmitting IP messages to end systems, which are not on the same subnet as

this controller.

This configures the ethernet port ENET2..

FTP Server

This address is optional, and is only required when the IP-based file download

options are to be used. The address must be that of the system where the FTP

server resides. This field is only used for local downloads from an FTP server

host on the local area network.

Database

This screen gives access to Consistency and Warning Checks and has a Database Copy Utility.

What is a Warning Check?

In the Cobalt controller, following a database download or object data alteration via key board,

the controller runs Consistency Checks to look for critical errors. If it detects errors, they must be

corrected or all database changes are discarded.

After you program the controller, it may appear that a certain feature does not operate correctly, but it

may be because of incorrect programming. To call attention to a possible incorrect programmed entry,

the controller generates a Warning. The controller generates a Warning if, in the opinion of Econolite,

you override the programmed parameter setting from a database with an unusual selection, or select

a combination of programmed values that may not give you the operation you probably expect.

Warning Checks are intelligent diagnostics designed to tell you of data entries that, by themselves or

in combination with other entries, may result in unexpected operation.

Important: One thing to keep in mind: a warning is not an error.

Occasionally, it could be that programming results in incorrect operation, but is acceptable to you

because it provides a benefit to you that compensates for an occasional operational anomaly. For

example, some users routinely program Walk and Pedestrian Clearance times that exceed phase

split times in coordinated operation because there are very few pedestrian calls and the user does

not mind the occasional coordinator resynchronization that follows the service of a pedestrian call.

Because we cannot possibly anticipate what you have in mind, it is left to you to decide what action, if

any, to take to correct the situation that caused a Warning message.

Cobalt by Econolite

* Cobalt Programming Manual - LIMITED DISTRIBUTION *

25/11/2013

Initially, the software framework and a limited set of diagnostics will be available. Warning Checks are

viewed as a long-term work-in-progress. These checks will be expanded as users and developers

find situations that cause an unexpected controller operation.

Select the condition for your application:

Database Hardware CRC Lock (Yes, No)

Request Database Download (Yes, No)

Automatic Backup to Datakey (Yes, No)

Enable VIOT Capture (Yes, No, Y + C)

Note: When you program Cobalt, you select Commit as necessary to enable the change to the

database. For an explanation of Transaction Mode (that runs when you make a critical change to

programming), refer to the Help for Home > Phase Order > Phase Order.

• Select Vehicle, Pedestrian or Overlap indication (Walk, Pedestrian Clear, and Don’t Walk) as the

source of each load switch and MMU channel.

• This selection applies only to TS2 operation with a TS2 MMU. It provides the selection of and

correlation between the indication and MMU channel to make sure that the load switch output

sensed by the MMU corresponds to the BIU command.

• This selection also allows the controller to redundantly check and verify the load switch outputs

indications as sensed by the MMU are as it commanded.

Assignment - 0 thru 16 for Vehicle and Pedestrian phases; A thru P for Overlaps (Green/Walk,

Yellow/Ped Clear and Red/Don’t Walk)

1. Select a number (with the scrubber) or letter (from the selection boxes) for the assignment

2. Select Commit at the top of the screen (or Rollback if you want to undo your selection)

Assignments are for each load switch and MMU channel.

0 (zero): deselects any control for that load switch.

This assignment applies only to TS2 operation with a TS2 MMU. It provides the assignment of

and correlation between the indication and MMU channel for verifying that the load switch output

sensed by the MMU corresponds to the BIU command.

Note: For TS2 operation, unused load switch/MMU Channels should be cleared of all Type and

Transaction Mode

IMPORTANT: To program an ASC/3 or an ATC 2070 Controller with ASC/3-2070 or ASC/3-

ATC software, it is necessary for you to understand Transaction Mode. Before you

proceed, read and understand this section about Transaction Mode.

Introduction

A Cobalt Controller contains a wide variety of Traffic features designed to give you maximum flexibility

in configuring an intersection. This broad base of applications requires database functions which, in

many cases, depend on other data entries to work properly. To ensure that critical data is entered

properly, the controller must run consistency checks on the database. These tests make sure

interrelated database functions are compatible with each other.

The consistency checks are done in what is called Transaction Mode.

Some data is relatively independent, such as timing entries. Other data, like the selection of controller

startup phases, depends on the phases and compatibilities of programmed sequence. These data

must be done within the Transaction Mode. Another type of data that triggers Transaction Mode is

one that has 2 or more functions — examples include HH:MM or 10.70.10.51.

Controller data may be modified manually via the keypad or remotely using SNMP/STMP messages.

In either case, critical data must be protected from incorrect or inconsistent changes.

Changing Data with the Keypad

If you attempt to modify a critical piece of data with the keypad (for example, controller start-up

phases), the controller automatically goes to Transaction Mode. A warning message will appear

on the display and the top line of the screen will flash. At this point, all changed data is stored in a

temporary buffer until you exit Transaction Mode.

When the Cobalt is in Transaction Mode, the controller gives you audio-visual indications as

explained below:

• Over the Database icon in the Status Bar, there is a rotating circular symbol and the selection of

Rollback (do not make a database change) or Commit (add the change to the database)

• As a reminder, if there is no key activity for 30 seconds, the controller will produce a continuous

beep sound and a pop-up reminder message will be displayed. This reminder is the same as the

message seen when you first triggered transaction mode and serves as a reminder to users who

Cobalt by Econolite

* Cobalt Programming Manual - LIMITED DISTRIBUTION *

25/11/2013

might not remember how to exit transaction mode. Any key activity will stop the buzzer but se-

lecting Rollback clears the transaction mode message.

• The front-panel LED will blink Fast Yellow

To exit Transaction Mode without saving the data, select Rollback.

To initiate the VERIFY state, once you have completed all of the changes, select

Commit.

During the verify state, the controller runs its consistency checks on the newly entered data. If

the data passes, then the changes are copied to the active database and Transaction Mode is

terminated. If the Consistency Checks find an error (for example, incompatible Startup Phases), then

the controller displays a description of the problem and gives you the option to disregard/throw away

all changes or to go back into Transaction Mode to correct the data.

Although the controller’s display will show your changes, it is important to note that those changes

will NOT take effect in the controller’s operation until Transaction Mode has exited. Also, if you cycle

power during Transaction Mode, then upon start-up all modified data will be lost. This is because the

modified data was only stored in the temporary buffer and never officially copied to the database.

Please note that not all data changes force the controller to Transaction Mode. Timing parameters

such as Minimum Green and Yellow Clearance may be modified as soon as you enter the data.

These changes take effect immediately.

Changing Data with SNMP/STMP

You may also change the Cobalt database with an SNMP or STMP SET message from Central. In

this case, it is Central’s responsibility to force the controller into Transaction Mode if critical data is to

be modified. Before SETs will be accepted on any P2 (or critical) objects, Central must send a SET to

dbCreateTransaction.0, changing it to a value of 2- transaction. At this point, Central may send any

number of SETs to database objects. These values are stored in a temporary buffer, the same as with

the manual keypad entry.

Once Central has completed its SNMP/STMP SETS and is ready to commit the new data to

the database, Central must send a 3-Verify to dbCreateTransaction.0. Cobalt will run the same

Consistency Checks as for the Keypad entry. Once completed, the controller internally sets the

transaction state to 6-DONE. If no errors were found, the new data is automatically copied to the

active database. Otherwise, the data is held in the temporary buffer until the discrepancies have been

corrected. (Central can see the error messages by doing a GET on the object, dbVerifyError.0.)

Summary

The Cobalt contains many database elements which are dependent on other entries. To ensure

proper controller operations, these dependencies must be checked before data is committed to the

active database.

Two methods exist to modify the controller’s database- keypad and NTCIP communications. Both

require Cobalt to enter a Transaction Mode state to allow Consistency Checks to run on the modified

data. If you cycle power BEFORE these checks can be run, then the modified data will be lost.

Also note that while the changes may appear on the controller’s screens, those values will NOT be

implemented in the controller’s operation until Transaction Mode is complete. That is, the Consistency

Check must be done before the new data is officially copied to the database.

these parameters whose functions are described below:

Protected

The Protected Overlap is a movement having a protected green arrow (no conflicting phases timing).

Note: When a phase has protected overlap phase assignments, Modifier, Lead, and Trailing

assignments are ignored (inhibited).

Select the phases for this type of overlap.

Ped Protected

The Pedestrian Protect option provides for the specification of phase pedestrian movements that

cannot be serviced while the overlap is active. If a pedestrian call is present on a pedestrian protected

phase when that phase becomes the phase next selection, the overlap is terminated while the ring

transitions from the timing phase to the phase with the protected pedestrian service. If a pedestrian

call is not present when the pedestrian protected phase becomes the phase next selection, the

overlap remains active if an included phase is timing or a phase next selection. Should a pedestrian

call be input while the ring is in yellow change or red clear on the way to the pedestrian protected

phase, the overlap is not terminated until the pedestrian protected phase starts and then only if there

is enough time to terminate the overlap and time the pedestrian movement before the phase will max

out.

Select the phases for this type of overlap.

Not Overlap

The Not Overlap option is provided to inhibit the activation of an overlap when selected phases are

timing. If an overlap is active when a call is placed on a not overlap phase, the phase is not allowed to

time until the overlap is terminated. If the order of rotation would normally allow the not overlap phase

to time, overlap termination will be initiated even if an overlap included phase is timing or a phase

next selection.

Select the phases for this type of overlap.

Lag X Phase

The Lag (Trailing) Overlap Phases option identifies which phases are to time programmed trailing

green, yellow, and red. If Trailing phases are defined, only those phases will time trailing green,

yellow, and red when they advance to yellow change and no other included phase is timing or a

phase next selection. If no Trailing phases are defined, then trailing green, yellow, and red are

disabled.

Select the phases for this type of overlap.

Cobalt by Econolite

* Cobalt Programming Manual - LIMITED DISTRIBUTION *

25/11/2013

Lag 2 Phase

For Lead Overlap Phases, when the overlap is active, the last timing overlap included phase is

advancing to yellow, no included phase is a phase next selection, and a Lead phase (that is not an

included phase) is next, trailing green, yellow, and red will be timed. This operation may be thought of

as timing a lagging overlap when proceeding to a particular phase.

When the overlap is not active and a Lead phase that is an included phase is a phase next selection,

overlap advance green will be displayed. Overlap advance green output starts, defined by the ADV

GRN time, when the phase of the ring that is transitioning to the included Lead phase begins its

yellow service.

Note: The Adv Grn time takes effect only if the lagging Yellow time is non-zero.

Select the phases for this type of overlap.

Lag Green, Yellow, Red

For Lag (Trailing) Green, Yellow and Red times, normally, if an included phase is terminating and no

other included phase is timing or a phase next selection, the terminating included phase’s yellow and

red are also output to the overlap. Trailing Green, Yellow, and Red provide a means of extending the

overlap’s green and then timing a specified yellow and red. When the last timing overlap included

phase begins its yellow change, the overlap’s green interval is extended by the specified Trailing

Green time. After Trailing Green has timed, Trailing Yellow and Trailing Red times are used to time the

overlap’s yellow change and red clearance intervals.

Note: Lagging times take effect only if the if the Green and Yellow entries are both non-zero.

Range is 0 to 25.5 seconds.

Adv Grn

Advance Green specifies the minimum amount of overlap advance green to be displayed before a

phase next selected included lead phase is started. If the amount of advance green is less than the

yellow change time and red clear timed by a ring before its phase next included lead phase can be

started, the overlap advance green is extended. If the amount of advance green is greater than the

yellow change and red clear timed by the ring before the overlap lead phase next selection would

normally start, the terminating ring phase’s red clearance is extended until the advance green time is

satisfied.

Overlap advance green output starts when the phase of the ring that is transitioning to the included

Lead phase begins its yellow service.

Range is 0 to 25.5 seconds.

Flash Green

Flash Overlap Green is specified for each included phase of an overlap and defines the rate at which

the overlap green interval is to flash when the included phase is timing.

For each phase, select a flash rate:

NF = no flash or phase is not an included phase for the overlap

F1 = flash at 1 pps.

F2 = flash at 2.5 pps.

F5 = flash at 5 pps.

The flash is extended across the transition from one included phase to another included phase if their

flash rates are the same.

Overlap green will be solid when transitioning between included phases that have different flash

rates.

state is used to derive the state of the overlap. In general terms, when any included phase is tim-

ing its green interval or the controller is advancing from one included phase to another included

phase, the overlap will be green. If no included phase is green, then the overlap will be yellow

when any included phase is yellow. If no included phase is green or yellow, the overlap will be

red. The usual derivation of the overlap state can be altered by more programming in the Details

tab.

To program a Minus Green Yellow type of overlap, in the Type drop-down menu, select –Green/

Yellow:

Top of the Screen (for both the Overlaps and Details tab)

The settings listed at the top of the screen show:

1. The Type of Overlap you are programming: -Green/Yellow

2. The overlap you are programming (A thru P)

3. The Guaranteed Overlap Green time, in seconds. You set this value in Home > Timing Plans

> Guaranteed.

Procedure to program a Minus Green Yellow Overlap

Note: Throughout this procedure, select Commit as necessary to enable the change to the

database. For an explanation of Transaction Mode (that runs when you make a critical change to

programming), refer to the Help for Home > Phase Order > Phase Order.

1. Select [Create Overlap].

2. A new overlap field (A, B, C, etc.) is shown in the overlap bar at the top. You can create up to 16

overlaps (A thru P).

3. Select a phase to Include in the overlap. The Included Phases specify the phases whose timing

state is used to derive the state of the overlap. In general terms, when any included phase is tim-

ing its green interval or the controller is advancing from one included phase to another included

phase, the overlap will be green. If no included phase is green, then the overlap will be yellow

when any included phase is yellow. If no included phase is green or yellow, the overlap will be

red. The usual derivation of the overlap state can be altered by more programming in the Details

tab.

4. Repeat Step 3 as necessary.

5. In the Included list on the left of the screen, each Minus Yellow Green overlap is listed with the

phases included in that overlap.

Note: To delete an overlap, select the overlap and then select [Remove Selected].

6. Select the Details tab and program the parameters as described in the table below.

Minus Green

Yellow Overlap

Parameter

Description Range

Modifier Phases

Select the Modifier Phase(s).

These Modifier Phases are used when the overlap type is Minus Green Yellow to

provide an overlap that will terminate to red during a modifier phase green and

yellow.

Note: When Modifier phases are assigned, only it and the Included Phases

option are used to decide the state of the overlap. All other overlap programming

options are ignored.
