JVL Industri Elektronik's latest firmware for the integrated servo motors MAC400 and MAC800 supports the MODBUS RTU protocol, using 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. 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.
