Overview

11.1 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.

1.2 RS-485 Communication (for UTAdvanced with RS-485 Communication)

Four protocols are supported on the RS-485 interface: PC link communication protocol, Modbus/RTU communication protocol, Modbus/ASCII communication protocol, and ladder communication protocol.RS-485 communication allows data to be collected from the UTAdvanced and data to be set on the UTAdvanced easily from a host computer.

Overview

11.3 Ethernet Communication (for UTAdvanced with Ethernet Communication)

The UT55A/UT35A with Ethernet communication can be connected to an IEEE802.3-compliant network (10BASE-T/100BASE-TX) and are capable of exchanging data with host computers, such as personal computers or PLCs (sequencers), using the MODBUS/TCP protocol.The UT55A/UT35A also has an RS-485 communication interface and the Ethernet-serial gateway function that relays the communication data received via network to the serial communication terminals. With this function, other serial communication devices not equipped with a network function can be connected to a network.

NoteIf you want to connect the UT75A/UT55A/UT35A/UP55A/UP35A to a network, you need to ensure consistency with the baud rate, connector, and the like. For details, consult with the administrator of the network to which to connect the UT75A/UT55A/UT35A/UP55A/UP35A.
