3.1

Installation of the CM35

3.1.1

Mounting the CM35

Before physical installation is begun, the appropriate safety precautions must
be taken and the following points complied with or clarified.

S

Was the module still in its original packaging?

S

Check the delivery for transportation damages.

S

Check the delivery for completeness.

If you discover damages or deficiencies, please contact
your SIEMENS representative.

The S7 interface of the CM35 corresponds to the serial I/O bus (P bus) of
the SIMATIC S7-300.

All slots on the SIMATIC S7 which can be assigned to signal modules (SM)

are available to the CM35.

For additional information, see the manual of the SIMATIC S7--300.

The maximum number of CM35 modules which can be installed on SIMA-
TIC programmable controllers depends on the following factors.

S

Maximum number of modules in the central rack/expansion unit or the
modular ET 200M I/O device

S

Memory requirements of the S5/S7/C7 CPU

S

Maximum permissible current consumption (5 V) from the S7 backplane
bus

For information on possible physical setups and how to configure, see
manual /70/.

Horizontal installation is recommended. When vertical installation is used,
remember that environmental temperatures are restricted (max. of 40

°

C).
