Correction
- Switch the supply voltage of the I/O-IPC off.
- Connect an I/O module for process data
to the I/O-IPC.
- Connect the end module as the last to the
I/O-IPC.
If no error argument is given by the I/O-LED,
the I/O-IPC interface is defective and the I/O-
IPC must be replaced.
- Switch the supply voltage of the I/O-IPC off.
- Replace the (n+1)th
process data module.
- Switch the supply voltage on again.
I/O modules that do not provide any data are not
considered (e.g., power supply module without
diagnostics).
- Switch the supply voltage of the I/O-IPC off.
- Replace the (n+1)th
process data module.
- Switch the supply voltage on again.
I/O modules that do not provide any data are not
considered (e.g., power supply module without
diagnostics).
- Switch the supply voltage of the
I/O-IPC off and reduce the number
of I/O modules.
- Switch the supply voltage on again.
