PLC plc system using wireless communication

摘要

The present invention is not limited to the case where the data cable passing through the process enclosure is removed so that the wiring is simplified and the installation work is facilitated and when the communication device includes a plurality of communication modules but the main communication module does not operate normally, It is possible to increase the safety and reliability of the data communication and to determine whether the communication device operates normally or whether the auxiliary communication module operates by a simple design change, The present invention relates to a PLC system using wireless communication that can maximize the process rate because it does not need to release the internal processing environment.;
