摘要：<p>A safety PLC is connected to a safety slave via a safety network so as to constitute a safety network system.The safety slave is connected to a plurality of safety devices and acquires safety input information sets from them and transmits information based on these safety input information sets in response to a request from the safety PLC.Here,two modes are available:a result notification mode to decide whether a safety condition is satisfied according to the safety input information sets and transmit the safety decision result;and a detailed information mode to report the safety input information sets directly as they are.The safety response is returned by one of the modes according to a command from the safety PLC.The result notification mode has a benefit of rapid response because of a small data amount while the detailed information mode assures details of information.</p>
