MBconnect Function Block Communication Error: code -19
I have 2 Modbus RTU networks with 16 slaves. Each Modbus network connected to a channel from CI853.
After a Download action, these networks have exhibited communication problems.
The MBconnect Function Blocks return -19 error code (I didn't find anything on the Control Builder M help).
However, I have one slave that it doesn't exhibit any communication problem (only one slave).
The main message present in the controller log is:
E 2015-09-23 10:18:14.010 VarClient, connection object in wrong state, Channel: 8.1.0, state:3
I attached a print screen file showed the controller log messages and connections from MBconnect Function Block.
Appreciate your help.Regards.
