    摘要： 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.

    摘要： A remote I/O system includes a plurality of slave stations, and a mater station. The master station includes a communication failure detector configured to assume that a communication failure occurred when the master station has not received a reply from a failed slave station among the slave stations. The master station has, as a failure operation mode, a partial communication halt mode where the master station stops communicating with the failed slave station, allows the failed slave station to maintain the communication failure by not performing a communication resuming process on the failed slave station, and continues to communicating with the rest of the slave stations except the failed slave station.

    摘要： A network system for carrying out communication between a control station and a plurality of devices connected to a network. The communication includes data communication which requires real-time attributes and message communication which does not require real-time attributes. The data communication includes a first data communication, and a second data communication. The system includes a plurality of transmission queues for temporarily storing transmission data provided in the control station, wherein one of the queues holds transmission data for the second communication. After the first data communication is carried out in accordance with a predetermined cycle time, an appropriate switching between the message communication and the second communication is carried out in the remaining time of the cycle time to complete one cycle, whereafter the cycle is repeatedly carried out.
