Using a PLC-5/40L, -5/60L

Programmable Controller

as an Extended-Local I/O

Use the extended-local I/O link when you need I/O updates more quickly than is possible from remote I/O link. An extended-local I/O link provides faster scan and update time than a remote I/O link. The extended-local I/O link is limited to 30.5 cable-m (100 cable-ft). If an I/O chassis is located more than 30.5m from the controller, you must use a remote I/O link.

PLC-5/60L

A PLC-5/40L or -5/60L controller (channel 2) and an extended-local I/O adapter module (1771-ALX) form an extended-local I/O link.

The extended-local I/O link is a parallel link that enables a PLC-5/40L or -5/60L controller to scan a maximum of 16 extended-local I/O chassis.

Due to the cabling design, you can remove an adapter module from a chassis on the extended-local I/O link without disrupting communication to other chassis on the extended-local I/O link.

Important: The PLC-5/40L and -5/60L controllers cannot be used as extended-local I/O adapters.
