Suspending a remote connection from Supervise

Purpose

If a remote PLC is being serviced, the operator will get communication alarms in the Alarm List. In that case, the operator may want to temporarily suspend the communication.

The DIALSUSPEND template

For that purpose, a template is included in every new IGSS configuration. The template is called DIALSUSPEND. By using this template, the operator has access to two additional commands compared to the DIALUP template: Suspend and Resume.

The template includes the following states and commands:

Create the suspend / resume object

In the following procedure, 7T recommends that you create two separate displays for this object. One for the normal commands: Connect, Disconnect and Fetch historical data and two buttons from which the operator can suspend and resume the remote connection.

Create the command field

1. In the Definition program, right-click at the diagram where you want to place the object.
2. Select New ® Command Field. The Object Browser dialog box appears.
3. Click the + sign beside the relevant area of the configuration.
4. Click the + sign beside Digital and select the DIALSUSPEND template.
5. At the bottom of the dialog box in the Create new object area, type the relevant name of the object, for example, DialNode0.

6. Click the Create button. The object properties dialog box appears.
7. On the Edit Mapping tab, do the following for both State and Command:

• Select the relevant driver and node number for the remote connection.
• In the Data Group and Word Offset fields, type the exact addresses specified on the Connection Misc tab for the node. It is recommended to set the Data Group and Word Offset to “0” to collect this type of status objects in this address range.

8. Click the Set Command Layout tab and do the following:

• In the Rows and # Cmds fields, type 3 to match the number of commands to display.
• Click the Show command and Shadow check boxes.
• Under Align, select Horizontal and click OK.

9. Place and resize the command field, the object name and state, as required.

• The operator will now be able to connect, disconnect and fetch historical data from the Supervise program.
