DMX Application Example

8.3.6.1

Operation with Deactivated Continuous Send

In this mode, the I/O module only transmits the data for a limited number of DMX
channels according to the set size of the process image (see table "Process data in
the DMX operating mode without continuous send"). Higher refresh rates are then
possible.

Not in use. In this mode, no data is received.
The transmission method is described in the chapter "Transmission of the
Character String 'Hello World!'"
8.3.6.2

Operation with Activated Continuous Send

In this mode, the output buffer filled with the DMX start byte (always 0) and then
with data for DMX channel 1 to 254.
The transmission method is described in the chapter "Continuous Send".
Observe settings!
To ensure continuous transmission, the "Continuous Send" setting must be
activated!
