The remote I/O connector at the back of the DL40 connects the DL40 to the
host PLC via the remote I/O link (Catalog No. 1746-RT29).
The remote I/O link begins at the scanner module. The scanner modules and
programmable controllers impose physical and logical limitations on the link.
You must know these limitations to avoid exceeding them.
