Sigma - Communicating with another controller, when using the service port, is not possible.

[Product_Support]

Issue

Communicating with a controller via its LAN connection, is not possible when connected to another controller's service port.

Product Line

Satchwell Sigma

Environment

Sigma all releases

Sigma all firmware versions.

Cause

The Sigma system is not complete, messages generated by the controllers cannot be sent to the Sigma server and therefore build up in the Alarm Buffers, this can prevent communications with other controllers..

Resolution

If a system is to be left without access to the backup/default Sigma server, then the following actions should be taken:

1. Do not programme any object alarms.
2. Do not configure any system logging.
3. Unless the network configuration allows access to all the appropriate controllers, do not configure globals.
4. Create an "Archive" of the controller.
5. If the time period without the Sigma server is to be less than 5 days, then it is possible to "Set Controller Mode".
6. To set the controller mode, go to System Diagnostics, then Options for the appropriate controller number, and then chose "Set Controller Mode". The following options are displayed.

Select the items you wish to inhibit, and set the time in minutes, (a maximum of 7200 can be set).
