Doing a test to get CS to talk to a Totalflox XFC G4 via Modbus TCP and running into some strange issues. The driver logs and IO logs don't seem to say anything obvious.

Issue: ClearSCADA says the Outstation is a Healthy Multidrop when NONE of the points are enabled, but as soon as I enable a even a single point tied to the Outstation, the Outstation Status immediately changes to Failed. Strangely enough, the time stamp and value of the point are updating, but the event log for the Outstation shows the outstation going from Healthy Multidrop, immediately to Failed every single poll. I have also noticed that the Totalflow will show the connected host when no points are enabled indicating the good connection with CS, but will not show any host when a point is enabled.

Currently using cellular communications, channel baud rate set to the max, and attempted 9600k also, 5 Comms Retries, 2 Transaction Attempts, 1000ms Standard Reply Delay, 250ms Inter Message Delay, 15s Reestablishment Interval, and 20s Idle Poll Interval. (Single Channel, Direct Outstation)

Totalflow is set to Modbus TCP port of 502, 32 bit Register Format (also set in CS), 60000ms Timeout, 20ms Response delay.

I found a work around. We set the TotalFlow to Modbus RTU over TCP and changed the CS Channel to RTU instead of TCP and and everything is working fine.
