COMMUNICATION FUNCTIONS
1.1
General
• This instrument provides a communication function through RS-485 interface, which allows data transmit to
or receive from the host computer and other devices.
• The communication system is comprised of a master station and slave stations. Up to 31 of slave station
(present instrument) can be connected per master station (host computer, programmable controller, graphic
display panel, etc.) through RS-485 interface.
• Because the master station can communicate with only one slave station at a time, the destination can be
identified by the "Station No" set for each slave station.
• In order that the master station and the slave station can communicate, the format of the transmit/receive data
must coincide. In this instrument, the format of the communication data is determined by the MODBUS
protocol.
