Properties
The reserve module (standby module) is characterized by the following properties:
• Is suitable for all terminal modules on which you can insert an electronic module.
• Reserves a slot for any electronic module. Plug the reserve module into the reserved slot of
the ET 200iSP con󹪝guration.
• If a gap (of an electronic module) occurs due to the ET 200iSP con󹪝guration, the following
rules apply:
– The gap is located at the last slot of the ET 200iSP: Insert a reserve module or the slot cover
into the gap.
– The gap is at a di󹪜erent slot (for electronic modules): Plug a reserve module into this gap
(see section Diagnostics for incorrect con󹪝guration states of the ET 200iSP with PROFIBUS
(Page 220)).
• As of product version 3, the reserve module can also be inserted onto the terminal module
TM-RM/RM.
Procedure with CiR
See function manual "Modifying the system during operation via CiR (
https://
support.automation.siemens.com/WW/view/en/14044916)".
Pin assignment
The reserve module has no connection to the terminals of the terminal module. This means that
you can wire the terminal module completely and prepare it for the future application.
