    MODBUS/TCP works according to the master/slave principle. The master is a superimposed control unit, i.e. a PC or a PLC device. The ETHERNET TCP/IP couplers of the WAGO-I/O-SYSTEM are slave devices. The master makes a query for communication. Through adressing, this query can be sent to a specific node.

    The TCP/IP protocol stack offers a high degree of reliability for the transmission of information. In the ETHERNET TCP/IP fieldbus coupler developed by WAGO, various application protocols have been implemented on the basis of the TCP/IP stack. These protocols allow the user to create applications (master applications) with standardized interfaces and transmit process data via an ETHERNET interface.
