RISK EVALUATION SUPPORT DEVICE, PROGRAM PRODUCT, AND METHOD FOR CONTROLLING SAFETY NETWORK RISK EVALUATION SUPPORT DEVICE

摘要

A risk evaluation parameter-setting table, where a danger source, input/output devices, and a PLC are related is generated by an MPU (25) based on network configuration information obtained via a communication interface unit (21) and device information on the devices, which form the safety network, obtained from a device information database (29). Operating information on the safety network is obtained via a communication interface unit according to the conditions prescribed in the risk evaluation parameter-setting table. The MPU uses an arithmetic expression to calculate the risk evaluation value of the current danger source based on the obtained operating information and displays the results on a display unit (23).
