WebThe Modbus communication interface is built around messages. The format of these Modbus messages is independent of the type of physical interface used. On plain old RS232 are the same messages used as on Modbus/TCP over Ethernet. This gives the Modbus interface definition a very long lifetime.
Web30 mrt. 2024 · And, TCP allows for multiple clients. Where RS-485 had an electrical limitation of 32 devices, Ethernet is unlimited. Operating RAM is the only practical limitation. There is the ability for a network designer to use multiple clients if they so choose with Modbus TCP. You need to get an expensive switch involved with TCP (Ethernet).
