Installing the Terminating Module and the Slot Cover
Properties
● The ET 200iSP distributed I/O station is terminated with the terminating module at the right
hand end of the ET 200iSP. Unless you have inserted a terminating module, the ET 200iSP
is not ready for operation (EMC is not ensured). While the ET 200iSP will start up, removal
of an electronic module will cause a station failure.
● Removal of an electronic module causes a station failure of the ET 200iSP.
● To secure the ET 200iSP mechanically, you must screw the terminating module to the
mounting rail.
● If your ET 200iSP configuration leaves you with a gap in the last slot, you must install a
reserve module or the slot cover in this slot.
– Install a slot cover if the ET 200iSP will not be expanded in the future. The slot cover is
integrated in the terminating module.
Replacing the slot cover with an electronic module during operation will cause a station
failure of the ET 200iSP.
– Install a reserve module if you want to use the free slot for a future expansion (by means
of an electronic module).
● The terminating module accompanies terminal modules TM-IM/EM and TM-IM/IM.
