Controller
The PanelView terminal is connected to a PLC in one of three ways:
•
Remote I/O link—The PanelView terminal is connected to a
single controller. The controller sends process information to the
terminal, such as messages, numeric data, or alarms. It also
solicits the PanelView terminal for operator input.
•
Data Highway Plus—The PanelView terminal is connected to a
peer-to-peer DH+ network that includes multiple controllers and
other devices. The terminal can control and monitor addresses in
these devices on the network.
•
ControlNet — The PanelView terminal is connected to a
peer-to-peer ControlNet network. The terminal can control and
monitor addresses in these devices on the network.
The PanelView terminal can optionally be connected as a device to a
Modbus network. For more information about using PanelView
terminals with Modbus, see the PanelBuilder 1400e Modbus User
Manual, Publication Number 2711E-6.12.
