Communication with S7-CPU via M-Bus 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.
An S7-1200 CPU is used in place of all SIMATIC PLCs. The layout diagram below shows the most important components of the solution for the communication between an S7-1200 CPU and the “UGW//micro PROFINET MBUS” gateway by MBS GmbH.
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).
