Abstract
A multiplex transmission apparatus includes a communication control circuit connected to a bus for successively receiving data from the bus, and the received data is output from an output port to a load via an output circuit. The successively received data is once stored in a receiving buffer and is then transferred to the output port. A port control circuit, which is connected to the output port, monitors the data transferred to the output port. When at least part of the data does not change in a predetermined manner in response to the data received immediately before, the port control circuit controls data outputted from the output port so that loads controlled according to the data from the output port are held in a safe state.
