Using MODBUS for Process Control and Automation

paper will focus on MODBUS RTU basics and application considerations. MODBUS/TCP is simply MODBUS over Ethernet. Instead of using device addresses to communicate with slave devices, IP addresses are used. With MODBUS/TCP, the MODBUS data is simply encapsulated inside a TCP/IP packet. Hence, any Ethernet network that supports TCP/
