(Note 1) Each contact is used for reading the operation state. Do not write over it with a user program.
(Note 2) In the case of the GPTRNS and pGPSEND instructions, the sending flag and send results flag are
updated after the scan is complete.
(Note 3) In the case of the GPSEND instruction, the sending flag and send results flag are updated after
sending is completed when the next GPSEND instruction is executed. If sending time is shorter than
scan time, the general-purpose communication sending flags (Y8, Y9, YA, YB) are turned OFF when
the GPSEND instruction is executed in the subsequent scan following completion of data sending. The
flags remain ON for at least one scan time.
