What to do if Omron Control Unit shows I/O BUS ERR?
If the Omron Control Unit displays an 'I/O BUS ERR' message, it indicates a connection error within the I/O expansion unit. To resolve this, switch off the power supply and carefully inspect the connections of the expansion units to ensure they are correctly connected.
What to do if Omron Control Unit displays UNIT OVER error?
If the Omron Control Unit shows a 'UNIT OVER' error, it means that more than 3 I/O expansion units are connected. To fix this, switch off the power supply and reduce the number of connected I/O expansion units to three or less.
What to do if Omron Control Unit shows I/O VRFY ERR?
If the Omron Control Unit displays an 'I/O VRFY ERR' message, it indicates that the type of bit set in the program cannot be used by the system. The suggested solution is to change the incorrect bit type within the program.
How to fix MEMORY ERR on Omron Control Unit?
A 'MEMORY ERR' on the Omron Control Unit indicates a program error, meaning the ladder program and parameter settings have been cleared. To resolve this, write a new program in ZEN.
