Modnet Driver Preformance

Miguel

Hello All

Please, someone can give me ideas to tuning better the Modnet Protocol.

we get some intermittent communication errors "I/O Device off-line, cannot talk".

We configured 55 IO Devices over Modnet Protocol reading about 200k Tags in the redundant system.

Thank you

  • Hi Miguel,
    It might be an idea to distribute this load across more IOServer instances. E.g. I'd recommend configuring about half the IO Devices to be on one IO Server, with the other half on a second IO Server. You can run several IO Servers on the same machine.
    You can also look at tuning [Modnet] Retry (default setting is 0) and Timeout (default setting 1000) to 1 and 2000 respectively.
