One of the machines i reprogrammed a while ago started giving me communication error 14 on hmi. Sadly i could find about the error is the station number of plc is exceeding the limit.
Anyone experienced such problem or any ideas what exactly exceeds what limit, data,memory,communication etc?
It was a working machine so i doubt it is program based. The error isnt constant, it only occurs when i start 2 of the 5 motors which are driven by Vfd. Analog outputs are used for frequency setting and analog inputs are used to monitor currents of motors.
When the error pops up screen freezes and cant do anything until i stop the monitors with emergency stop.
