Terminal Connections Chapter 12

Making Remote I/O Connections

To connect a PanelView terminal to a remote I/O scanner, use cable

Catalog No. 1770-CD (equivalent to Belden 9463). The maximum

cable length (link distance) is determined by the communication rate.

• 2,800 m (10,000 ft) for 57.6K baud

• 1,400 m (5,000 ft) for 115.2K baud

• 700 m (2,500 ft) for 230.4K baud

See Programmable Controller Wiring and Grounding Guidelines,

publication 1770-4.1. The user manual for the I/O scanner module

also provides cabling information.

TIP

The polarity of the remote I/O connector on the PanelView

terminal is reversed from the PLC Scanner connector. However,

the polarity is the same as the scanner card connection to the

SLC controller.

TIP

If the terminal is the last device on the link, connect a 1/2 watt

terminating resistor across terminals 1 and 2. The value of the

resistor depends on the remote I/O communication rate:

• for 57.6 kilobaud and 115.2 kilobaud, use a 150-ohm resistor

• for 230 kilobaud, use an 82-ohm resistor
