Functional limitations based on different operating conditions!
The "DMX receive" function has been tested under certain operating conditions.
If the I/O module is operated in conditions other than those listed in this section, it
can lead to functional limitations and data loss.
Additional information on using DMX functions is listed in the "DMX_01

The application note is available for download at the
Note the process image size setting!
In "DMX receive" mode, the correct process image size must be set.
To operate the I/O module in DMX Slave mode, the 24-byte process image size
(default) must be used!
Incorrect operating parameters can lead to functional limitations and instable
operation. Operating parameters are listed below that ensure stable operation.
