Communication


What you will find in this section:

  1. Modbus/RTU via RS-485 
  2. PROFINET and/or EtherNet/IP™

 

All devices are equipped with an Ethernet interface with an RJ45 socket.

Other communication interfaces can also be available optionally.

  • RS-485
  • PROFINET
  • EtherNet/IP™

Write and read access

All devices are equipped with an integrated Ethernet interface (X1) with an RJ45 socket.

The device configuration is performed via this Ethernet interface.

Other communication interfaces can also be available optionally.

Modbus/RTU

Write and read access

 

The device configuration can be implemented via the Modbus/RTU interface (RS-485) or via the integrated Ethernet interface.

 

PROFINET and/or EtherNet/IP™

Read access

X3

PROFINET and/or EtherNet/IP™

Read access

 

The interfaces (X2 and X3) do not offer any options for device configuration and can therefore not be reached via the display or the web server.

The interfaces only offer a read function for the data via the dual ports (2xRJ45).

The associated IP addresses are assigned accordingly via the controller.

You can use one or two communication protocols with only one cable. To do so, bridge interfaces X1 and X3. Via the interface X2, both protocols (Modbus/TCP and PROFINET, or Modbus/TCP and EtherNet/IP™) can now be used in parallel.
