Designing a Remote I/O Link

6-4Communicating with Remote I/O

Follow these steps for setting up a remote I/O system:

For this Step	See
1.configure the remote I/O adapter devices	the device’s user manual
2.layout and connect the remote I/O link cable	• page 6-4for design
	• chapter 3 for cable routing information
	• your controller’s installation information
	(For enhanced PLC-5 controllers, see publication
	1785-IN062; for Ethernet PLC-5 controllers
	publication 1785-IN063)
3.configure the scanner channel	page 6-6

Designing a remote I/O link requires applying:

•remote I/O link design guidelines

•cable design guidelines

Link Design Guidelines

		Keep these rules in mind as you design remote I/O links:
	TIP	Keep these rules in mind as you design remote I/O links:
	TIP
		• All devices connected to a remote I/O link must
		• All devices connected to a remote I/O link must
		communicate using the same communication rate,
		either 57.6, 115.2, or 230.4 kbps. Choose a rate that all
		devices support.
		• Two or more channels of the same controller operating
		in scanner mode cannot scan the same partial or full
		rack address. Assign unique partial and full racks to
		each channel used in remote I/O scanner mode.
		• You can split rack addresses between scanner channels;
		however, issues arise when performing block-data
		transfer. See page 6-15.
		• A scan list can have a maximum of 16 rack numbers or
		a maximum of 32 physical devices connected to it using
		82-Ωtermination resistors. See page 6-9for more
		information about scan lists.
