Modbus Interface problem - i/o timeout in tags

hello

 

We are working with a Modbus interface "PI ModbusE 4.0.7.86" which has 6 nodes (IP 's). The problem is that at a certain point, for some reason, the interface stops receiving data.

After that, the interface tries to obtain data only once and then not try again. As a result, the tag returns "i/o timeout".

 

To remedy this, we set in the configuration file parameters "/cn" to increase the number of attempts at reading and "/to" to increase the timeout to retry reading . Both configurations do not provide us any solution.

 

if anyone can help I would appreciate.

Finally, there is some way that the interface will automatically reboot in this situation?

 

Thank you!.
