2. The Data Transfer Function
Data can be received from and sent to another Programmable Controller in the same network by using the
F145(SEND)/P145(PSEND) and F146(RECV)/P146(PRECV) instructions.
A maximum of 16 words( one word = 16 bits) can be transferred at a time.
This function can be performed between all of the stations(Max. 32) in the same network.
Notes :
[Example 1]
"Station 01" sends the data, stored in the data registers starting with DT0, to the data registers starting with DT0
of "Station 02".
[Example 2]
"Station 02" receives the data, stored in the data registers starting with DT10 of "Station 01", and stores the data
in the data registers starting with DT20 of the "Station 02".

• This function can be performed between all of the stations(Max. 32) in the same network.
• This function is available for all of the W Type(Wire) Link Units installed in a single CPU.
If other P/W Link units, such as a P Type(Optical) Link Unit, C.C.U.(Computer Communication Unit)
or a C-NET Link Unit, are installed together in one CPU, the total number of P/W Link units must not
exceed 3 units.
• Refer to page 38,"Data Transfer" for details about Data Transfer function.
