S7-1200 MODBUS TCP Communication Multi-Request Handling Rules to be followed for individual client connections: 1. Each “MB_CLIENT” connection needs to use a different background data block; 2. Each “MB_CLIENT” connection must specify a server IP address; 3. Each “MB_CLIENT” connection must specify a unique connection ID; 4. Whether a unique IP port number is required … Read more
Recently, I used the S7-1200 to collect data from a certain flow sensor via Modbus-RTU. The Siemens side chose the CM1241 (RS422/485) (order number 6ES7 241-1CH32-0XB0, firmware version V2.2), and the CPU is 1214C with firmware version V4.2. I thought the debugging would be simple, but it took a lot of time, and I consulted … Read more
