echolink one2PROFINET

Intelligent Protocol Converter for Integrating Serial Devices into PROFINET Networks

The intelligent echolink one2PROFINET coupler connects various devices and automation components to PROFINET networks via their RS232, RS485 and RS422 serial interfaces. The WINGATE configuration tool with graphical user interface is available for parameterizing the communication between the serial port and the fieldbus. Common protocols such as Modbus ASCII or Modbus RTU (master or slave) are also supported.

echolink one2PROFINET is supplied as a narrow DIN rail module according to IP20 and can be used flexibly or exchanged without additional effort. A suitable GSDML file is available in the download area.
