Replacing the F I/O Module

The process of 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.
The process of replacing an F I/O module with an F I/O module of a different type
is always associated with a new project configuration (see Section
"Commissioning" > ... > "Programming the Safe PLC").
9.1.1

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 use this setting for the replacement module.
• Plug the replacement module into the fieldbus node in the position of the
F I/O module to be replaced.
• Switch the power to the fieldbus node in question back on.
Then perform the one of the following steps, depending 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 this F I/O module is operated with iPar server functionality,
read section "Service" > "Replacing the F I/O Module" > "F I/O Module with
iPar Server Functionality" > "PROFIsafe Address Set Using the Coding
Switch."
• If the coding switch setting of the F I/O module to be replaced has a value
of 0, and this F I/O module is operated with iPar server functionality, read
section "Service" > "Replacing the F I/O Module" > "F I/O Module with iPar
Server Functionality" > "PROFIsafe Address Set Using the
Parameterization Tool."
