CONTROL-BUS ERR.

What does 1413 mean?

In a multiple CPU system, a CPU module incompatible with the multiple CPU system is mounted. This means an incorrect CPU type has been installed in the main base unit, preventing proper system operation. Alternatively, it could be a self-diagnostic error in the system bus or CPU module, or a mismatch in the control CPU setting for other CPUs compared to CPU No.1.

• A CPU module incompatible with the multiple CPU system is mounted.
• Self-diagnostic error in the system bus.
• Self-diagnostic error in the CPU module.
• In a multiple CPU system, the control CPU setting of other CPUs, configured in the I/O Assignment tab of the PLC Parameter dialog box, differs from that of CPU No.1.

Click steps to track your progress.

1. 1

   Remove the CPU module incompatible with the multiple CPU system from the main base unit, or replace the CPU module with a CPU module compatible with the multiple CPU system.

2. 2

   Reset the CPU module and RUN it again. If the same error is displayed again, the intelligent function module, CPU module or base unit is faulty.

3. 3

   Reconfigure the control CPU setting of other CPUs so that it can be the same as that of CPU No.1.
