Modbus TCP is a simple bus protocol. It is recommended to read or write about 100 words at a time. The communication cycle for a single read or write is about 70 ms. When possible, choose instead real-time Ethernet protocols, such as PROFINET and Ethernet/IP, Siemens Snap7 (corresponding to Mech-Vision Siemens PLC Client in the Standard Interface communication), or Mitsubishi MELSEC (the MC protocol). |
