 Using MEMOBUS (MODBUS) Communications
Serial communication is available with VS-606V7 using programmable
controller (MEMOCON series) and MEMOBUS (MODBUS). Refer to
MEMOBUS Instruction Manual (Manual No.: TOEZ-C736-70.1) for
details of communications.
 MEMOBUS (MODBUS) Communications
MEMOBUS system is composed of a single master (PLC) and slaves (1
to 31 VS-606V7 units).
Communication between master and slave (serial communication) is
controlled according to the master program with the master initiating
communication and the slave responding.
The master sends a signal to one slave at a time. Each slave has a pre-
registered address No., and the master specifies the number and conduct
signal communications. The slave receives the communications to
carry out designated functions and reply to the master.
