Modbus TCP Connection Down -7001
Hi,
We have one CI867 unit used with AC800M Controller PM866. We noticed that the TCP connection is up and down (Icon turning yellow and red alternately at hardware tree).
And MBTCP Connect Block, the status is showing 1 and -7001 alternately.
Do you have a solution to this issue?

This problem can also occurs, while You are not only one master reading slave device at the same time. Try to extend watchdog for it.
Another issue is that, You writing block is wrongly connected - You will only write once in Yours case. Request needs to be pulsed by logic (write only when detected rising edge on input)

There is a known bug in v6 which causes a similar error. Are you using the latest version of CI867ModbusTcpHwLib?
