The implementation supports the Read Holding Registers and Write Multiple Registers commands, which will give R/W access to all motor registers at speeds up to 1 Mbit/s, though typically the PC standard rates of 9600..115200 and 230400 bits/s would be used.
The implementation uses the original V1.1 version of the MODBUS protocol for maximum compatibility. For systems requiring a 2-wire RS-485, the MAC00-P4 interface module is used. For 4-wire RS-422, the MAC00-FSx modules or one of the MAC00-Bx modules are used.
MODBUS is generally considered the most widely used serial communications protocol in the industry.
