• Easy wiring
The FP3/FP5 W Type(Wire) Link Units are connected with a twisted pair cable, which makes the initial wiring
and wiring maintenance easy. Data communication is easily performed between Programmable Controllers.
• High speed, long distance transmission
Data can be transmitted at the speed of 500k bps between stations which can be a maximum of 800 m /
2,624.672 ft. apart.
• A maximum of 3 W Type(Wire) Link Units can be installed on a singleMaster Backplane.
Each CPU can control a maximum of 3 P/W Link units*. If you install other types of P/W Link units*, such as a
P Type(Optical) Link Unit, a C.C.U.(Computer Communication Unit) or a C-NET Link Unit, the total number of
P/W Link units must be 3 or less.
• In the W Type(Wire) Link System, the following 3 useful functions are available :
<P/W PC Link function>
A P/W PC Link is formally called a "P Type(Optical)/W Type(Wire) Programmable Controller Link".
In the P/W PC Link, data are easily exchanged between Programmable Controllers using link relays(L) and
link data registers(LD).
A maximum of 16 stations in a network can be set in PC Link Mode to be included in the P/W Link System.
A maximum of 2 W Type(Wire) Link Units can be used as stations in PC Link Mode in a single CPU.
If you install units with a P/W PC Link function, such as a P Type(Optical) Link Unit, the total number of
units in PC Link Mode must not be more than 2 units in one CPU.
<Data Transfer function>
Data can be transferred between Programmable Controllers using F145(SEND) / P145(PSEND) and
F146(RECV) / P146(PRECV) instructions. This function is available to all of the stations (Max. 32 stations)
in a network.
<Remote Programming function>
Programming, system register setting and data read out of remotely located Programmable Controller can be
controlled from any Programmable Controller located close to you. This function is available to all of the sta-
tions(Max. 32 stations) in a network.
