1-3. Main Functions of the W Type(Wire)
Link System
The W Type(Wire) Link System provides three kinds of communication functions between FP3s and FP5s as
follows :
A P/W PC Link function(optional function)
A Data Transfer function
A Remote Programming function

1. The P/W PC Link Function

Data can be shared among FP3s and FP5s in a network by using 1,024 link relays(L) and 128 link data
registers(LD).
This function can be performed between W Type(Wire) Link Units set in PC Link Mode.
(In the same network, both of FP3s and FP5s can be installed.)
Notes :
• A maximum of 16 stations in a single network can be set in PC Link Mode.
• A maximum of 2 W type(Wire) Link Units installed on a single CPU can be set in PC Link Mode .
If other units with a P/W PC Link function, such as a P Type(Optical) Link Unit, are installed together,
the total number of units with a P/W PC Link function must not exceed 2 units for each CPU.
•Refer to page 27, "P/W PC Link" for details about the P/W PC Link functions.

The figure above shows an example of a P/W PC Link under the following conditions :
• The operating status in the "Station 01" will change according to the ON/OFF state of the link relay L0 in the
CPU controlling "Station 02".
• When data stored in WX1 is written to link data register LD1 at "Station 02", "Station 01" reads the data stored in
LD1 and writes it in WY1 of its CPU.
Thus data transfer from WX1 in "Station 02" to WY1 in "Station 01" can be easily performed by using link data
register LD1.
