Copley Modbus TCP/IP Introduction: Function Code, Read/Write, IP, DHCP

What are Modbus-TCP Function Codes 3 and 16 and how to read/write two 16 bit words as most Copley parameters are 32 bits. How Ethernet TCP-IP provides CRC (error checking). What is IP (Internet Protocol) Address and how to set it in the drive. Example: "g r0x11F x" IP Address 0x17020a0a = 10.10.2.23 What is DHCP (Dynamic Host Configuration Protocol) and how to turn it on/off. "s r0x121 0x201" Network Configuration bit 9 Ethernet bit 0 DHCP
