3-3 LR Area Division Tables
The PC Link Unit has the ability to transfer from 2 to 32 words (32 to 512
bits) of data between PCs. The LR area is divided according to the number of
PC Link Units and the number of Subsystems in the System. Refer to the
appropriate table for your System. Any unused portion of the LR area may be
used as work bits. The number of LR bits transferred per Unit and Single-le-
vel/Multilevel designation are made on switches on the PC Link Units.
