I am getting intermittent #COM with on a particular Port which communicates to DNP devices. In the syslog I can see a "General Error" and DNPR and Driver Error 00065544 (0x00010008)


This is likely to be an Application Layer timeout. You can view this in the Kernel >> Driver >> DNPR (Press V for verbose). Bottom left hand corner you will see "Appl Timeouts" and "Appl Fails". You can take a look at these and confirm if the values are increasing.

A likely cause is that the DNPR port is too busy to respond to requests. You should increase [DNPR]EventPollPeriodDefault
