The WATCH-DOG Module is used to monitor the ISYGLT subnet. An application case is switching to an emergency operating level when errors are detected in the BUS or the Power Supply. Short-circuits and interruptions of the BUS line or a failed Master Module can be detected with the module. This module can be used to switch redundant BUS segments to a second Master Module, for example, or to control corresponding emergency operation relays in sub-distribution boxes in the event of failure/emergency. The time until the output is activated when an error is detected can be adjusted via parameter setting. A test function is also available in BUS operation.

8-pole DIP switch for setting the ISYGLT BUS address (0-127) is located under the cover of the module.
| DIP-1 | Setting |
|---|---|
| OFF | BUS operation |
| ON | No function, but adjustable by parameter |
| LED | Designation | State | Meaning |
|---|---|---|---|
| red | Power | Off | No operating voltage |
| On | Operating voltage, no error | ||
| yellow | BUS | Off / On | Error BUS |
| blinking | Interference-free data transmission via the BUS line | ||
| 4x green | BUS failure | blinking | LEDs signal a BUS failure by chaser animation, LED 1 is on during BUS operation |
In the ISYGLT ProgramDesigner there are various parameterisation possibilities:
| =Ub | Operating voltage |
| 0V | 0V Operating voltage |
| A | BUS A (subnet RS-485) |
| B | BUS B (subnet RS-485) |
| CE | Common potential for E1-E4 (e.g. 0V) |
| E1 | Input 1 |
