Overview
1 1.1 UTAdvanced Communication
The UTAdvanced communication supports RS-485 communication and Ethernet
communication.
Three types of RS-485 communication are provided.
Host communication: Modbus communication, PC link communication, and ladder
communication that enable centralized monitoring of the UTAdvanced by a host
computer.
Coordinated operation: A system of coordinated operation is configured with a master
controller and a number of slave controllers, all of which are UTAdvanced. The slave
controllers are set to operate in the same way as the master controller.
Peer-to-peer communication: Enables sharing of data with other UTAdvanced by reading
and writing peer-to-peer communication registers in the ladder program.
The UTAdvanced with Ethernet communication can be connected to IEEE802.3-
compliant network (10BASE-T/100BASETX). A serial gateway function can increase the
number of connected controllers.
