Function Description
By limiting the maximum channel number to 5, 21 or 45 (at a set process image
size of the I/O module of 8, 24 or 48 bytes), refresh rates of 1 ... 16 updates per
second are possible.
5.1.6.2
Receiving Data Packets in DMX Mode
DMX packets can also be received in DMX mode with firmware version 06 or
higher. In this mode, control commands can also be transmitted to a WAGO
controller in systems in which DMX control is generated, for example, from a
lighting control desk. Building lighting or other elements that have conventional
controls can be implemented.
Malfunction when process image size is set incorrectly!
In "DMX receive" mode, the process image size must be set to 24 bytes.
Process image sizes of 8 bytes and 48 bytes are not permitted!
The I/O module can receive data from successive DMX channels from any
address range of the entire DMX packet (DMX universe) and transmit to the
associated fieldbus master. The size of the address range corresponds to the set
process image size of the I/O module of 24 bytes and accordingly, allows receipt of
21 consecutive DMX channels.
The number of the first received channel (start of the address range) can be set.
You need WAGO-I/O-CHECK Version 3.10.8 or higher to set the DMX start
channel number.
Additional Information
Further information on the structure of the process data in DMX mode and the
dependency of the address range from the set process image is available in
section "Commissioning" > ... > "Mode when Receiving DMX Data".
Note settings in "DMX receive" mode!
Further information on correct settings in "DMX receive" mode is available in
section "Commissioning" > ... > "'DMX receive' Operating Parameters"!
5.2
Data Exchange Operating Mode
In the data exchange operating mode, the I/O module allows cyclic data exchange
with another 750-652 I/O module configured in the same operating mode. Process
data between different fieldbus nodes can also be exchanged when integrated in
different fieldbus systems.
