摘要： Control information from a plurality of applications 1000 is written into a shared memory 101 as needed. A communication part 105 transmits the control information written in the shared memory 101 to a DHM 200 in each transmission cycle which is constant. In a management table, a plurality of allowable delay times is defined, the allowable delay time being a delay time allowable at an urgent transmission of the control information. A transmission timing notification part 106 divides a transmission cycle into time slots each of which is equal to or shorter than the shortest allowable delay time defined in the management table. The communication part 105 transmits the control information in the shared memory 101 to the DHM 200 before arrival of the transmission cycle, in a unit of time slot.

摘要： A communication unit receives from a BCM output data which is data to I/O devices from the BCM. A shared memory stores the output data received by the communication unit. An anomaly detection communication processing unit and the communication unit generate a communication frame for anomaly detection to request sending the output data held in the BCM. The communication unit sends the communication frame for the anomaly detection to the BCM, and receives the output data held in the BCM from the BCM as a response to the communication frame for the anomaly detection. The anomaly detection checking unit compares the output data received from the BCM with the output data stored in the shared memory.
