Programming

8.1

This section is intended only for XML users.

Requirement: The XML interface has been activated in WBM.

You can program the reader via the XML interface using XML commands. You can find

detailed information on this in the manual "XML programming for SIMATIC Ident

support.industry.siemens.com/cs/ww/en/view/109781631)".

8.2

This section is intended only for Modbus users.

Requirement: The Modbus interface has been activated in WBM.

Specific function blocks for programming the Modbus interface are available to you

depending on the controller used. When connected to S7-1200/1500, the reader is

programmed using the "MB_CLIENT" function block. This function block supports a wide

variety of Modbus functions. The basic functions for reading the UID and tag fields are

already implemented in the WBM of the reader and the data can easily be requested in this

way. Via the WBM, you can easily create tag fields and determine which transponder data can

be read out via the Modbus interface. You can find more information on this in the section

"The "Settings - Reader configuration" menu item (Page 43)".

You can find a detailed description of the "MB_CLIENT" function block on the Siemens

Industry Online Support (https://support.industry.siemens.com/cs/ww/en/view/62830463)

pages.

NOTICE

Access to the reader

Remember that simultaneous access to a reader using multiple Modbus clients is possible but

not recommended.

If changes are made when two Modbus clients are accessing a reader at the same time, this can

lead to errors in the configuration or to an undesired result.
