Siemens S7-200/S7-300 PLC 187.5K Communication Speed Manual
The document provides instructions for configuring the MPI 187.5 kbit/s communication speed on Siemens S7‑200 and S7‑300 PLC series. It lists compatible modules such as MT8100iV2, MT8070iH2, MT6070iH2, MT6100iV2 and MT6050iV2, and shows the required settings in the PLC software.
Only one HMI can be connected to a Siemens 187.5 kbit/s device at a time, and communication is limited to either COM1 or COM3 using RS‑485 (2‑wire). The MT6050iV2 module supports only COM1 RS‑485, while other modules allow both COM1 and COM3. Pin‑out details for the RS‑485 connector are also provided. This manual is written in Japanese.
