Example 2:
If it is required that when the front door or back door of the rack is open, the alarm lamp turns on. Suppose that the
DI1 and DI2 ports of the RDU-A G2 are respectively connected with the door status sensors on the front and back
door, and the alarm lamp is mounted on the DO1 port. You can achieve the alarm linkage function through the
following configuration:
Expression: [RDU-A DI1 Alarm] OR [RDU-A DI2 Alarm] = [RDU-A DO1] [Close]
The configuration method is shown in Figure 3-45. When the alarm signal of RDU-A G2 DI1 Open or RDU-A G2 DI2
Open generates an alarm, RDU-A G2 DO1 will close, thus the alarm lamp turns on.
