Ethernet IP Adapter to PROFINET Controller Gateway

Integration of PROFINET I/O Devices through mapping into Ethernet IP Control systems

The epGate PN implements a gateway between an EtherNet/IP scanner (e.g. a Rockwell PLC) and up to 32 PROFINET devices. While the gateway's upper RJ45 socket connects to the EtherNet/IP network as a so-called Adapter (slave), the gateway acts as a PROFINET controller (master) through its lower RJ45 socket. This allows for integration of PROFINET devices and subsystems into EtherNet/IP applications. The Communication Configuration Tool that comes with epGate PN assists in defining the PROFINET configuration and provides ready to use symbolic mapping information for the EtheNet/IP PLC's engineering software. This way the user is relieved from the error-prone task of defining data for both sides of the gateway individually.


Reliable Operation Across Networks Boundaries

  • Connection to the EtherNet/IP network via the so- called adapter (slave); (upper RJ45 socket)
  • PROFINET controller (Master) functionality (lower RJ45 socket)
  • Direct access from EtherNet/IP scanner in the PLC to PROFINET field devices
  • Access to machines with internal PROFINET network by deploying I-Device capabilities (Support of Siemens PLCs)
  • Transparent exchange of I/O data
  • EtherNet/IP side is informed about PROFINET faults and diagnostics
  • EtherNet/IP PLC can activate PROFINET outputs explicitely by a quality value
  • PROFINET outputs switch to safe state if connection to the PLC is lost

Simple Integration Through Add-On Instructions

  • Data access of PLC program to PROFINET devices without requiring detailed PROFINET knowledge
  • Mapping between the two protocols generated by provided tools
  • Use of Add-On Instructions (AOI) containing detailed PROFINET data type definitions
  • Transparent communication overcoming protocol differences

Including configuration tool and integrated web server

  • PC-based configuration software for online access to PROFINET Devices with ready to use symbolic mapping information for the EtheNet/IP PLC‘s engineering software
  • Built-In web server for monitoring of mapping as well as of exchanged data
