The network I/O relay modules can also be connected to a network door controller, AXIS A1001 or AXIS A1601 (with firmware 1.41 or higher), to support elevator access control. The communication between the two devices is controlled by the door controller, which is the master device, and the I/O relay module is the slave.
Once the I/O relay module is connected to the door controller, the client can easily discover, monitor and control the output ports on the I/O relay module, just as if the output ports were located on the door controller. The whole access control logic is located on the door controller, no extra or special configuration is needed, the elevator floor level is simpy interpreted as a door in the door controller's system.
