Error Code 4: Physical Error in the Internal Data Bus
-
Internal data bus
communication error or
interruption of the internal
data bus at the I/O-IPC
- 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.
n*
Interruption of the internal
data bus behind the nth
process data module.
- 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).
Error Code 5: Internal Data Bus Initialization Error
n* Register
communication
error during internal data
bus initialization
- 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).
Error Code 6: Design Error in the Node Configuration
5
Maximum size of the
process image exceeded
- Switch the supply voltage of the
I/O-IPC off and reduce the number
of I/O modules.
- Switch the supply voltage on again.
