In the present invention a control device and a safety device establish a connection in accordance with a result of a comparison of connection setting information stored in the control device and setting identification information stored in the safety device. A support device is provided with a processor for executing a support program for assisting in setting the control device. A support program includes a first command for acquiring the setting identification information from the safety device and a second command for setting, in the connection setting information corresponding to the safety device, the setting identification information acquired in response to execution of the first command. Thus, the required identification information can easily be set even when a plurality of safety devices are connected to the same network.

Support device, non-transitory computer-readable recording medium recording support program, and setting method

An information processing device collects information on an operating state of a communication system formed of a master device that manages communication over a network and at least one slave device connected to the network and capable of performing communication as instructed by the master device. The master device and the slave device record communication log entries regarding time information and a communication state in accordance with communication processing. The information processing device includes an acquiring section that acquires communication log entries from at least one of the master device and the slave device, a log entry rearranging section that rearranges the acquired communication log entries based on the time information, and a log entry extracting section that extracts, out of the rearranged communication log entries, any communication log entry recorded within a predetermined period of time from occurrence of a communication log entry including communication abnormality information.

Information processing device, information processing device control method and control program

A safety master configured to communicate with a plurality of safety slaves over a safety field network or with a plurality of safety local I/O units connected by a safety back plane bus of the safety master, wherein each of the plurality of safety slaves and safety local I/O units allow connection to safety I/O devices in a plurality of cell equipment, and wherein the safety master receives a status signal indicating a 'safe state' or an 'unsafe state' related to cell equipment from each of the corresponding plurality of safety slaves or safety local I/O units, and controls operation/stop of cell equipment by executing an interlock operation program with the received status signal as an input to output an operation instruction signal.
