 Handling Unit Errors
When an error occurs in the built-in analog I/O system, analog input data will be set to 0000 and the
analog output will be set to 0 V or 0 mA.
If a CPU error occurs, the analog output will be set to is set to 0 V or 0 mA even if the output range is
1 to 5 V or 4 to 20 mA. For any other fatal errors in the CPU Unit, 1 V or 4 mA will be output if the
output range is 1 to 5 V or 4 to 20 mA.
