WAGO-I/O-SYSTEM 750
753-647 DALI Multi-Master
In the "Full mode", acyclic data transfer with the PLC is implemented using a
mailbox interface via acyclic transmission channels (see section "Process
Image" >... > "Full Mode").
As mentioned above, an "Easy mode" is also available which enables lighting
control using simple binary signals without any complicated PLC programming
(see section "Process Image" > ... > "Easy Mode").
The "Easy mode" is the standard state for the DALI Multi-Master Module.
The "Full mode" can be activated via PLC modules.
The behavior in the event of a local bus failure or lack of communication with the
higher-level controller can be monitored by enabling a watchdog (see section
"Process Image" > ... > "Watchdog").
8 colored LEDs on the I/O module enclosure signal active and inactive operating
modes, data transfer via DALI and the data bus, application of DALI bus power
and internal statuses or errors of the I/O module. The LEDs also signal the
identification function with FW version 20 or higher (see section "Display
Elements").
The I/O module 753-647 can be used with fieldbus couplers and fieldbus
controllers of the WAGO-I/O-SYSTEM 750.
