Command And Acknowledgement Frames; General Structure Of The Adapted Commend Frame - Siemens SIMATIC RF650R Configuration Manual

A.3

Command and acknowledgement frames

This section is intended for both S7 and Rockwell users.
The communications principle of the Ident blocks described in this manual is based on the
"Proxy Ident Function Block" specification. If you want to program your own blocks for
configuring your RF680R/RF685R readers, make sure that they are created so that they
conform to this specification.
You can obtain the specification of the "Proxy Ident Function Block" from the PROFIBUS
User Organization. You will also find further information in the manual "Ident Profile and
Ident Blocks, Standard Function for RFID systems".
NOTICE
Deviations from the specification
Some of the command frames of the specification were adapted and differ from those listed
in the specification. These adapted command frames as well as the unchanged command
frames used are described in the following sections.
