Replacing the F I/O Module

Replacing an F I/O module with an F I/O module of the same type is described
below.
Only replace modules when the system is in a safe state!
Modules must only be replaced when the system is in a safe state.
Replacing an F I/O module with an F I/O module of a different type is always
associated with a new project design (see Section "Commissioning" > ... >
"Programming the Safe PLC").
10.1.1

Procedure

When replacing an F I/O module, first perform the following steps:
•
Switch off the supply voltage of the fieldbus node containing the F I/O
module to be replaced.
•
Pull the F I/O module to be replaced out of the fieldbus node (see Section
"Assembly" > ... > "Inserting and Removing Devices").
•
Read the PROFIsafe address on the coding switch of the F I/O module to
be replaced and enter this setting on the replacement module.
•
Plug the replacement module into the position of the F I/O module to be
replaced in the fieldbus node.
- Switch the power to the affected fieldbus node back on.
Then perform one of the following steps based on your system configuration:
•
If the coding switch setting of the F I/O module to be replaced has a value
other than 0 and it is operated with iPar server functionality, continue
reading in Section "Service" > ... > "PROFIsafe Address Set Using the
Coding Switch."
•
If the coding switch of the F I/O module to be replaced is set to 0 and it is
operated with iPar server functionality, continue reading in Section
"Service" > ... > "PROFIsafe Address Set Using the Parameterization Tool."
•
If the coding switch of the F I/O module to be replaced is set to a value
other than 0 and it is operated without iPar server functionality, continue
reading in Section "Service" > ... > "PROFIsafe Address Set Using the
Coding Switch."
