Connect Terminal to
Modbus Network
Before running your application, you need to connect the PanelView
Plus/PanelView Plus CE terminal to a Modbus network using either:
• Modbus serial cables or
• Modbus Ethernet cables
Modbus Serial Cables
The serial port on a PanelView Plus/PanelView Plus CE terminal is
different than a desktop computer. Typically, you just need to add a
null modem adapter to a cable that works with a desktop computer.
To create a cable specifically for the PanelView Plus/PanelView Plus
CE, use the cable descriptions in this section for Modbus Serial
KEPServer drivers (RTU Serial, Unsolicited Serial, ASCII Serial).
