■

Signal modules from the SIMATIC S7-400 range can be used in 

the SIMATIC PCS 7 automation system if necessary. These are 

primarily an alternative to use of distributed I/Os in the case of 

small applications or systems with a small distributed configura-

tion.
For SIMATIC PCS 7, the I/O modules listed in the Ordering data 

have been selected from the range of S7-400 signal modules.

Apart from these selected modules it is also possible to use - 

with limitations in functions - all other I/O modules from the cur-

rent range of S7-400 signal modules.
All process data from the I/O are available for PCS 7 engineering 

in the CFC, and can be graphically interconnected to the signal 

name in the signal list. Diagnostics information is generated au-

tomatically when using the I/O modules listed here.
When using other I/O modules, integration in SIMATIC PCS 7 

is limited to the process data, i.e. the full scope of diagnostics 

functions is not automatically available. These modules can 

therefore only be used meaningfully in SIMATIC PCS 7 if the 

diagnostics capability can be omitted.
Online modifications and redundancy are not supported by the 

central I/O.

trollers / SIMATIC S7"
