Replacement of a communication module

This section describes the failure and replacement of communication modules for
PROFIBUS and Industrial Ethernet.
The failure and replacement of communication modules for PROFIBUS DP is detailed in
Replacement of a PROFIBUS DP master (Page 234).

Replacement of failed components during redundant operation
What to do?
Disconnect the module from its peripheral
power supply, if necessary.
Disconnect the front connector and wiring.
Remove the failed module (in RUN mode).
Insert the new module.
Plug the front connector into the new mod-
ule.
13.1 Replacement of central components
How does the system react?
If the affected module can generate
•
diagnostic interrupts and if diagnostic in-
terrupts are enabled as per configura-
tion, a diagnostic interrupt is generated.
Call OB 122 if you are accessing the
•
module by direct access
Call OB 85 if you are accessing the
•
module using the process image
Both CPUs generate a remove/insert
•
interrupt and enter the event in the di-
agnostic buffer and the system status
list.
Both CPUs generate a remove/insert
•
interrupt and enter the event in the di-

Parameters are assigned automatically
•
to the module by the CPU concerned
and the module is addressed again.
