How can I set up an MPI network in a Siemens S7-1200 PLC?

For setting up an MPI (Message Passing Interface)) network in a Siemens S7-1200 PLC, start by using the PLC’s MPI (Multi Point Interface) port, which allows communication with other Siemens devices such as HMIs, other PLCs, and programming devices.

Here’s a step-by-step procedures:

Step-1: Physical Connection: Utilizing a compatible MPI cable, connect the PLC’s MPI port to the MPI port of the other Siemens device.

Step-2: Software Setup: Start the TIA Portal software and create a new project for the S7-1200 PLC.

Step-3: Device Configuration: Go to the “Devices & Networks” section of the TIA Portal.

Step-4: Device Addition: Click “Add New Device” & choose your S7-1200 PLC from the set of available devices.

Step-5: MPI Configuration: To configure the MPI settings for the PLC, right-click on it in the project view, pick “Properties,” and then go to the “General” tab to enter the MPI address.

Step-6: Network Configuration: To configure the MPI network, right-click on “Networks” in the project view & select “Add new device”. Select “MPI” as the network type & enter the MPI address of the PLC.

Step-7: Device Integration: Add the other Siemens device to the MPI network’s settings in the TIA Portal.

Step-8: Project Download: Transfer the specified project to the PLC & test MPI connection between devices.

Following these steps will allow you to configure an MPI network in a Siemens S7-1200 PLC, allowing for seamless communication with the other Siemens devices via the MPI port.
