To prevent the VERSAMAX SE device from timing out due to inactivity, the following recommendation is made:
Configure the timeout on the device's COM port and SE Interface to 60 seconds.
Add the global parameter S90TCP_<DEVICE_ID>_IS_SE with a value of "Y" for each SE device.
The connection and request time out values on the TCP/IP tab of the port configuration need to be set to a value that ensures consistency in establishing and maintaining a connection. A value of 55 seconds (55000 ms) is recommended as an initial starting point. An initial value of 5 to 10 seconds may be configured for the heartbeat timer to reduce the possibility of timeout due to inactivity. It is desirable that the request timeout plus the network latency be less than the time out value configured in the SE and PLC Port configurations.
Add the global parameter S90TCP_RECONNECT_DELAY with a value of "10". This is the time by which to attempt to perform a reconnect.
Open the Triplex project in Workbench and then, from the Tools menu, select Command Prompt.
Type "idtpop device" and press Enter.
Open the device.idt file in a text editor. The device.idt file is located in the project folder (e.g. C:\Program Files\GE Fanuc\Proficy CIMPLICITY\MyTriplexProject).
For the device in question, change the dead_scan_rate from 45 to a smaller number, such as 10, and save the file.
In the Command Prompt window, type "scpop device" and press Enter.
In Workbench, from the Project menu, select Configuration Update. A message appears asking to copy the master configuration data to run-time data.
When you start the project, it should recover 20 to 30 seconds after a failover/recovery.
Where SE devices are configured on the port, the mode address must have a valid PLC address even if there are no redundant devices configured on the port.
The first time that a connection is established via the S90 Triplex in a project after loading a project later than 6.0 SP1, the memory sizes from the PLC will be read at startup regardless of the setting in the device configuration.
