I have a PLC with 3x DX200 controllers. I'm reading and writing registers via Modbus TCP to update the PLC as to where the robot is in it's cycle, getting cycle times, etc etc.
Unfortunately in South Africa we are plagued by Electricity supply problems due to poor management at our power utility.
Occasionally, the communication between the PLC and DX200 will be interrupted by a PLC reset or something. When this happens, I'm unable to re-establish the connections to the DX200's without resetting the controllers. The connection doesn't seem to timeout or reset on the controllers to allow a new connection to be established.
Is there a way to set a Modbus TCP communications timeout or manually reset the connection?
