Risk evaluation support device, program product and method for controlling safety network risk evaluation support device

A program product for carrying out risk evaluation for a safety network, said safety network serving to cause an output device to make a controlled device operable based on a detection signal outputted from an input device when said input device detects a safety condition, said program product comprising program parts carrying out the steps of:

• obtaining configuration data of said safety network and device data on devices that form said safety network and creating a parameter setting table for risk evaluation based on said obtained configuration data of said safety network and device data, said parameter setting table correlating a danger source with said input device and said output device;
• obtaining operating data for said safety network according to conditions provided by said parameter setting table for risk evaluation;
• calculating a current risk evaluation value for said danger source based on said obtained operating data;
• and
• outputting data related to said risk evaluation value.
