16.10 How to Remove or Replace Modules
An I/O module, ROM or DIM can be replaced with another of the same type, without needing to re-program the configuration
as TPPR can copy the configuration to the new module. However, see the Warning and Cautions below before proceeding.
Note: Administrator level access is required to decommission / recommission / reconfigure modules via software, but a
qualified electrical engineer should carry out the physical work of removing or replacing the modules.
Note: Replace will only work if replacing with the same module type and only if Modification states are compatible. In
addition, mV modules will require recalibration of used channels.
16.10.1 How to Remove or Decommission an I/O Module
1. Login as an Administrator.
2. Go to System Setup.
3. Decommission the channels / modules you want to remove. (You will get a warning later on if you fail to do this
correctly.)
e) Identify whether or not the module’s channels are in a normal C&E Matrix. To do this, try to decommission the
channel and the software will tell you what outputs are associated with it (Error 49). However, no warning is
given if the channel is in a master C&E Matrix.
f) Similarly, if the channel is in a remote interaction group associated with a DIM (i.e. remote acknowledge, reset
etc.), you have to remove it from the DIM, and the quickest way is to try and decommission it as in (a) above.
4. If it is in a C&E or group, edit each output channel or DIM in turn to remove the link. To do this:
g) Note down which channel or DIM is affected as this information will be lost in decommissioning.
h) Edit each channel in turn, removing it from the C&E Matrix.
i) Return to the System Setup screen.
5. Decommission each channel.
6. Select Remove. The module will no longer appear on the Ring and can be removed when ready. (Do not manually
re-initialise the ring or you will have to remove the module again.)
7. Disconnect the field equipment cables from the faulty module.
8. Remove the faulty module from the Communication / Power Rail by pulling down the clip at the bottom and easing
the module carefully outwards before unhooking it from the top of the DIN rail.
Note: Decommissioning can be done in software with or without the module being present. If the module is present it will be
set to an un-initialised state (flashing LED). It will show as a Fault if not present.
16.10.2 How to Remove or Decommission a ROM or DIM
ROMs and DIMs are removed in the same way as I/O Modules. It is the user’s responsibility to consider any effects on the
cause and effect matrix.
Avoid static discharge when installing or replacing any module.
If the TPPR relays are switching mains voltages, hazardous live terminals may be present within the
Relay Output Modules even if the TPPR is electrically isolated.
