Operand Description Range Data type Data type (label)
(U) GP.BUFRCV Start I/O number (first three digits in four-digit
hexadecimal representation) of own station or own
node 00H to FEH 16-bit unsigned binary ANY16
ZP.BUFRCV Start I/O number (first three digits in four-digit
hexadecimal representation) of own station or own
node 00H to FEH String ANY16_OR_STRING_
SINGLE
(s1) Connection No. 1 to 16 16-bit unsigned binary ANY16
(s2) Start device of the own station where control data is
stored Refer to the control data. Device name ANY16
*1
(d1) Own station start device for storing the receive data

Device name ANY16
*1
(d2) Device of the own station, which turns on for one
scan upon completion of the instruction.
When the instruction completes with an error, (d2)+1
also turns on.  Bit ANYBIT_ARRAY
