Modulebus Max scan time setting is locked at 100ms what could be locking it? the available max should be 300ms.
CBM Version 5.1.0/1 Build (18.104.22.168)
We need to increase the scan time to reduce the controller load.
Looks like the help file may be wrong. My CBM says 100ms Max as well.
You can avoid IO scanning load entirely by using either Profibus or Profinet. If you have a large volume of IO, then only put signals that you need to scan at a very high rate on direct IO. Put everything else on Profibus.
