A.1 Prerequisites
The following prerequisites must be observed as regards the use of S5
modules in the S7-400:
 Check with your local Siemens office that the modules you want to use
have been approved for implementation.
 Programmable S5 modules can be linked into a STEP 7 user program
only with special standard function blocks. Should you have only standard
S5 function blocks for your S5 modules which are not expressly autho-
rized for STEP 7 implementation in the associated documentation
(Manual or Product Information), you must order new standard function
blocks for those modules.
 SIMATIC S5 and SIMATIC S7 differ from one another in their general
technical specifications, most particularly those relating to ambient condi-
tions. When installing an S5 module in an S7-400, the most stringent am-
bient conditions for either the S5 and S7 apply for the system as a whole.
The adapter casing may be installed only in the S7-400 central rack.
Note
Before installing an S5 module which has been used in an S5 configuration
in an S7 system, always call your local Siemens office for particulars. The
information provided in this chapter relates exclusively to the current ver-
sions and revision level of the S5 modules covered.
