2.2 Product description
rack, but provide a lower throughput rate. The module variant you choose depends on your
application requirements.
Note
The 32-byte interface is only supported by the serial interface modules with Article No.
6ES7 138-4DF01-0AB0!
The serial interface modules with Article No. 6ES7 138-4DF00-0AB0 only support 4-byte and
8-byte interfaces!
Function blocks are required to manage communication. The function blocks for the
SIMOTION system are described in this manual; these function blocks are handled differently
than the function blocks for SIMATIC S7.
Functionality of the ET 200S 1SI serial interface module
The functionality of the function blocks and the ET 200S 1SI serial interface module in a
SIMOTION system is the same as that in SIMATIC S7.
The following ET 200S 1SI serial interface modules are not supported by the function blocks:
● 1SI Modbus Master (4, 8, 32 bytes)
● 1SI USS Master (4, 8, 32 bytes)
Possible applications
You can use the ET 200S 1SI serial interface module without restrictions in a SIMOTION
system. For this to be possible, the module must be operated as a distributed module via an
ET 200S I/O system and a PROFIBUS connection to the SIMOTION system.
You can operate multiple ET 200S 1SI serial interface modules on one SIMOTION device.
The following figure illustrates how to connect an ET 200S distributed I/O system with an IM
151-1 and two serial interface modules on a SIMOTION device (e.g. SIMOTION C2xx).
