Operand Description
(U) GP.BUFRCV Start I/O number (first three digits in four-digit
hexadecimal representation) of own station or own
node
ZP.BUFRCV Start I/O number (first three digits in four-digit
hexadecimal representation) of own station or own
node
(s1) Connection No.
(s2) Start device of the own station where control data is
stored
(d1) Own station start device for storing the receive data
(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.
