Xml Interface; Functionality Of The Xml Interface - Siemens SIMATIC RF650R Configuration Manual

XML interface

This section is intended only for XML users (RF650R/RF680R/RF685R).
This section describes the use of the XML interface of the RF650R, RF680R and RF685R
readers. When using the XML interface, you can operate the readers via Ethernet. You can
do the following:
● Read out and write transponder data via the reader
● Read out reader information
● Read out reader configuration
● Receive tag events
● Receive messages
● Receive RSSI events
● Process IO

Functionality of the XML interface

The XML interface is based on command/reply frames and the reader can also send
asynchronous reports. Each command that you send is replied to by the reader with a reply
frame regardless of whether the command was executed successfully or not. If errors occur
during communication, the reply frame contains an error description.
To ensure unique assignment of the commands and replies, each command must include a
unique ID. This ID is repeated in the corresponding reply frame.
Normally, the reader replies to a command within 5 seconds. We recommend that you
program your application so that if this time is exceeded, the application starts appropriate
error handling.
Some commands (e.g. "setConfiguration" or "readTagIds") can take longer than 5 seconds.
These commands already include information to this effect.
Note
Saving and working through the commands
It is also possible to send several commands without waiting for the replies. The reader
works through the commands in the precise order in which they were received. Note that the
reader discards newly arriving commands if internally there are already approximately 100
commands waiting for execution.
