3. F146(RECV)/P146(PRECV) Instruction
Link data receive
[F146(RECV, steps : 9), P146(PRECV, steps : 9) ]
Outlines
The F146(RECV) instruction receives data from another Programmable Controller in the network
whenever the trigger is turned ON.
The P146(PRECV) instruction receivesdata from another Programmable Controller in the network
only when the leading edge of the trigger is detected.

Description
R9030
0 : When data cannot be transferred.
(including the time while data are being transferred.)
1 : When data can be transferred.
R9031
0 : When the transfer operation has completed without error.
1 : When a transfer error occurs.

R9007
Turns ON and stays the ON,
• when the data specified in “S1 +1” and/or “S1” is out of range.
• when the unit cannot be found.
• when the ending memory area address(Source/Destination) specified using “S1 + 1”,
“S1”, “D” and “N” is beyond the limits of the specified memory area.
(The error program address is stored in DT9017.)
R9008
Turns ON for an instant,
• when data specified in “S1 +1” and/or “S1” is out of range.
• when the unit cannot be found.
• when the ending memory area address(Source/Destination) specified using “S1 + 1”,
“S1”, “D” and “N” is beyond the limits of the specified memory area.
(The error program address is stored in DT9018.)
S1
Memory area address for setting the conditions for this instruction.
(addresses S1 + 1 & S1 are used)
S2
Source memory area type in another station.
(always specified as "0")
N
