1) Instructs the master module to read data from the buffer memory specified in (S1)+2 and (S1)+3 of the
station specified in (S1)+1.
2) The master module monitors the remote input (RX) specified in (S2)+1.
3) When the remote input (RX) specified in (S2)+1 turns ON from OFF, the master module reads data from the
buffer memory of the specified station.
Read data are stored in the receive buffer of the master module.
4) The master module turns the remote output (RY) specified in (S2)+0 ON.
When the remote input specified in (S)+1 turns OFF from ON, the remote output specified in (S2)+0 turns OFF.
5) Data read out from the specified station are stored in the device specified in (D1) and subsequent devices,
and a device specified in D2 turns ON.
(b) The G(P).RIRCV instruction can be executed to multiple intelligent device stations
simultaneously.
Note that concurrent execution of multiple instructions including other dedicated instruction(s) (refer to
Page 191, Section 9.1) is not allowed to the same local station or intelligent device station.
Create a program in which a flag remains on until the instruction is completed.
