    The TCP/IP protocol stack offers a high degree of reliability for the transmission of information. In the ETHERNET based (programmable) fieldbus couplers and controllers developed by WAGO, usually 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.
