SIMATIC S7-1500, CM PTP RS422/485 BA communication module for serial connection RS422, RS485 Freeport, 3964 (R), USS, 19200 kBit/s, 15-pin Sub-D socket. SIMATIC ET 200MP is a modular, scalable, and universally applicable peripheral system in IP20 and offers the same system advantages as the S7-1500. It allows for the shortest bus cycle times and fastest response times even with large quantities of data. The decentralized peripheral system is particularly easy to install, wire, and commission. With its scalable design, you can precisely tailor the peripheral station to the specific needs on-site. Communication modules enhance the communication capabilities of the ET 200MP with additional interfaces.
