Safety condition setting support device, program product and device control method for obtaining safety condition for safety network

A computer readable program product for a safety condition setting support device for a safety network, said safety network connecting to safety devices including an output device and an input device and serving to cause said output device to stop a controlled apparatus, when said input device has detected a danger condition, based on a detection signal outputted from said input device, said safety condition setting support device serving to set safety conditions for stopping said controlled apparatus within a specified time period, said program product comprising program parts carrying out the steps of:

• obtaining at least either of transmission interval between said connected safety devices and safety distance between said input device and said controlled apparatus;
• obtaining connection data showing connection relationship between said safety devices;
• reading out and thereby obtaining internal processing times of said safety devices from an apparatus data memory that stores data related to said internal processing times;
• and
• carrying out a calculation process based on the data obtained by the aforementioned steps and thereby obtaining said safety conditions.

A method of controlling a support device for a safety network, said safety network serving to cause an output device to stop a controlled apparatus, when an input device has detected a danger condition, based on a detection signal outputted from said input device, said support device serving to set safety conditions for stopping said controlled apparatus within a specified time period, said method comprising the steps of:

• preliminarily storing in said support device apparatus data related to internal processing times of safety devices connected to said safety network including said input device and said output device;
• causing said support device to obtain connection data showing connection relationship between said safety devices and at least either of transmission interval between said connected safety devices and safety distance between said input device and said controlled apparatus;
• and
• causing said support device to obtain said safety conditions based on said connection data and said either of transmission interval and said safety distance obtained by said support device and said preliminarily stored apparatus data.
