4-2.P/W PC Link
When Connecting a P/W PC LINK 0 station to a P/W PC LINK 1 station
When the P/W PC Link function is used, it is possible to connect a W Type(Wire) Link Unit which is assigned
as P/W PC LINK 0 to a W Type(Wire) Link Unit which is assigned as P/W PC LINK 1.
In this case, special attention is required when allocating the PC Link Area since the addresses for P/W PC LINK
0 and P/W PC LINK 1 are not in same absolute address range. When allocating the PC Link Area, the relative
addresses should be carefully considered.
