Introduction
The KL2692 Bus Terminal monitors a bit that is toggled by the controller during each cycle. If the toggle signal fails, the terminal switches off two potential-free relays in order to prevent damage to the machine. Failure of the toggle signal may be caused by the PLC cycle stopping, by a fault in the bus cable or connector, or by a fault in a bus device. The cycle monitoring time can be parameterized. The Bus Terminal has an enable input that enables the relay to be switched on if a correct toggle signal is detected.
