Basics of Configuring Hardware with STEP 7
The following table provides information on each individual slave family:
DP Slave Type Exchangeable Conditions for Exchange
DP slaves whose properties
are specified by GSD files
(additional information...)
No -
DP-As-i Link No -
DP/PA Link Yes Maximum configuration of the DP master cannot be
exceeded (I/O address space, number of slots)
A redundantly operated DP/PA link can only be
exchanged for a DP/PA link that can be operated
redundantly.
ET 200L SC and IM SC Yes You must be able to put all inserted modules into the
new DP slave.
ET 200M (IM 153-x) Yes Cannot be exchanged if:
• For the old ET 200M, the function "Change
Modules during Operation" was activated and the
new ET 200M does not support the function
• CPs/FMs with their own MPI address (for example,
FM 353)
• Modules are inserted in the old ET 200M which
cannot be inserted in the new ET 200M
• The old ET 200M was operated redundantly and
the new ET 200M cannot be operated redundantly
ET 200S (IM 151-1) Yes Cannot be exchanged with IM 151/CPU
ET 200S (IM 151/CPU) Yes Cannot be exchanged with IM 151-1
ET 200X
Yes You must be able to put all inserted modules into the
(X-BM 141.., X-BM 142..)
new DP slave.
An X-BM 143/DESINA cannot be exchanged for other
ET 200X basic modules and vice versa
Cannot be exchanged with X-BM 147/CPU
ET 200X BM 147/CPU Yes Cannot be exchanged with X-BM 141..., X-BM 142...
and X-BM 143...
Which DP Slaves Are Specified by GSD files?
DP slaves whose properties are specified by GSD files (device database files) are
located in the Hardware Catalog in the "Other Field Devices" folder or also in the
"CP 342-5 as DP-Master" folder, for example. Those DP Slaves (also called
"Standard Slaves") can be identified by specifying the GSD file or type file in the
"Order no." row or in the "DP Slave properties" dialog, "General" tab.
