Dali-1 Compatibility - WAGO 750 Series Manual

WAGO-I/O-SYSTEM 750
753-647 DALI Multi-Master
For operation with 2 DALI Multi-Master Modules (753-647) in one DALI line, the
"Network Polling after Power On" parameter must be disabled for one of the two
753-647s. The same applies to the "Enable Internal Power Supply" parameter.
You disable these using the WAGO DALI configurator by unchecking the box
next to the respective parameter.
To avoid collisions between data packets, you should also set the "Control gear
polling interval [s]" with enabled cyclic control gear polling for both DALI Multi-
Master Modules (753-647)!
Change from HW03 / FW20
This restriction is no longer mandatory for the current hardware/firmware version
or higher. 2 DALI Multi-Master Modules start now even if the parameter is
enabled in both.

DALI-1 Compatibility

Because the DALI-1 standard was not subject to certification tests, electronic
control gear (ECG) has hit the market that did not comply with the timing
requirements of EN 62386. While the WAGO DALI-1 module was still allowed to
make allowances for timing ranges beyond the defined limits in terms of firmware,
and thus could be very tolerant for communication, this is no longer permitted in
accordance with the new DALI-2 standard. With the introduction of the DALI-2
standard, the limits for permissible timing are now also being checked.
If you are using DALI ECGs with faulty timing behavior in your system, the new
753-647 module (distinguishable by the word "DALI-2" and the DALI-2 logo) can
go into DALI-1 compatibility mode by downgrading the firmware when replacing
the DALI Multi-Master Module (753-647). This firmware is available from WAGO
Support on request.
Please note that in such case, the DALI-2 certification expires and must also be
rendered unrecognizable on the I/O module (lettering and logo must be crossed
out). In addition, it should be noted that the extended functionalities of DALI-2
controllers and control gear (e.g., extended fade times and manufacturer-specific
operating modes) are no longer supported when downgrading.
