Integration Via Communication Modules; Control With Ident Profile - Siemens SIMATIC MV550 S Operating Instructions Manual

Process interfacing via an automation system (PLC, PC)

9.2 Integration via communication modules

Configuration with FB 79 or the Ident profile
Depending on the function block you are using, you must select the required function block
in the properties of the reader in the tab "General" > Parameter group "Mode".
9.2 Integration via communication modules
The optical reader supports a subset of communication module parameters.
Via the RS422 interface, the optical reader can be integrated in a control system using a
communication module (CM). Integration via a communication module is described in the
respective operating instructions of the relevant CM.
When configuring the communication module in conjunction with the optical reader, you can
set the following parameters in the hardware configuration:

Control with Ident profile

This section explains a process connection using the Ident profile. The use of the FB 45 via
a communication module is still possible, but is no longer recommended. With the FB 45,
systems that are already operated with the FB 45 today can continue to be operated
compatibly with MV500. You can find information on operation with FB 45 in the manuals
"SIMATIC MV420 / SIMATIC MV440
(https://support.industry.siemens.com/cs/ww/en/view/84553392)" and "FB 45 for MOBY U,
MOBY D, RF200, RF300 (https://support.industry.siemens.com/cs/ww/en/view/21738808)".
You can find an overview of the compatible communication modules in the section "Process
connection via an automation system (PLC, PC) (Page 103)".
