For one IM 300-5, you can connect up to three EUs to a CC or EU in
distributed arrangement (see Figures 7-5 and 7-6). The EUs are supplied with
operating voltage via the IMs. Any free connections on the IM 300-5 and the
last IM 312-5 require no terminator.
Note
The maximum permissible current over each connection of the
IM 300-5CA11 is 5 A.
You can connect up to four EUs to each IM 300-3. The last IM 312-3
requires a terminator.
You can connect up to three ERs to each IM 300-5L (-5LB11). The ERs are
supplied with operating voltage via the IMs.
Note
The maximum permissible current over each connection of the
IM 300-5LB11 is 2 A.
The connection of central controller and expansion unit to the IM 300-5LB11
is provided exclusively by the 705-0 connecting cable. It is available in two
lengths: 0.5 m and 1.5 m (refer to the ordering information for order
numbers).
When the IM 300s are used in the S5-135U/155U PLC, the input/output
modules can be addressed in the normal (P) and extended (O) areas.
You may only set module addresses in the EU which are not used in the CC.
This applies to both areas.
