4-2.P/W PC Link
Allocating the area for P/W PC Link
• Each PC Link Area(P/W PC LINK 0 and P/W PC LINK 1) should be allocated its own areas(relay and data
link areas) as a separate send area and receive area.
• The send area addresses in each memory cell should not be overlapped in the same network.
If the send area addresses overlap each other in the same network, an error will occur.

• The data in the "Send 1" area is transferred to the "Receive 1" area in stations 02, 03 and 04.
• The data in the "Send 2" area is transferred to the "Receive 2" area in stations 01, 03 and 04.
• The data in the "Send 3" area is transferred to the "Receive 3" area in stations 01, 02 and 04.
• There is no send area in the sation number 04(UNIT NO. 04) in this network.
• Send and receive area settings must be assigned for both the link relays(L) and the link data
registers(LD).
• The send area addresses in each memory map(P/W PC LINK 0/P/W PC LINK 1) should not be over-
lapped in the same network. If the send area relative addresses overlap in the same network, an error will
occur. Be sure to allocate non-overlapping the send areas.
