  • Entry
  • Associated product(s)
This application example shows, how to configure a communication between SIMATIC PLC and a M-Bus network with a gateway.

Gateways enable the communication between two networks that use different communication protocols. M-Bus (Meter-Bus) is a network protocol used in transfering data from consumption meters.
The task is to create a communication connection between a SIMATIC PLC via PROFINET interface using a M-Bus gateway. The objective of this document is to discuss the gateway suitable for this task and how the configuration between SIMATIC PLC and the gateway is realized.

The application presented here offers the following advantages:
  • The application example can simply be adjusted to other controller families.
  • The application example can be simply adjusted for plant expansions.
  • The tools for configuring and commissioning for the gateway are onboard (Webserver).
