Remote I/O
These PLCs can
be set up in scan-
ner mode. In this
way, 2706-DL40
displays may be
connected directly
to the processor.
No external scan-
ner is needed.
The PLC 5/11, -5/15, -5/20, -5/25, -5/30, -5/40, -5/60, and -5/80 have built-in
Remote I/O scanners.
Like all scanners, built-in scanners have both physical and logical
specifications. See Table 10.D on page 10-7.
