P/W Pc Link; Pc Link Area - Panasonic FP3 Technical Manual

4-2.P/W PC Link

The P/W PC Link is one of the functions available with a W Type(Wire) Link System.
In a P/W PC Link, data is shared between Programmable Controllers by writing or reading data in memory areas
called link relays(L) and link data registers(LD) which exist in each Programming Contoller.
Since no special instructions for data communication are required when using the P/W PC Link function, you can
create programs without needing complicated procedures.
Notes :
• A maximum of 16 stations in a single network can be in the PC Link Mode.
• A maximum of 2 W Type(Wire) Link Units on a single CPU can be set in PC Link Mode.
If other units with P/W PC Link function, such as a P Type(Optical) Link Unit, are installed together
on the CPU, the total number of units with a P/W PC Link function must not be more than 2 units.

1. PC Link Area

Each CPU has 2 PC Link Areas(P/W PC LINK 0 and P/W PC LINK1) and each PC Link Area is composed of 2
types of areas(relay link area and data link area).
In the P/W PC Link for the FP3/FP5 Programmable Controllers, the PC Link Areas available are as follows:
For "P/W PC LINK 0" : Max. 1,024 points relay link[link relays(L) : L0 to L63F]
For "P/W PC LINK 1" : Max. 1,024 points relay link[link relays(L) : L640 ot L127F]
[P/W PC Link Communication Examples]
[EXAMPLE 1]
• Turning ON the external output relay Y30 in the FP5 at station number 15 (UNIT NO.15) when the
external input relay X0 in the FP3 at station number 01(UNIT NO. 01) is turned ON.
