● For the GPSEND instruction, it is necessary to turn ON the execution condition until the end of
data sending, and turn OFF the execution condition at a scan in which the end of data sending
is confirmed.

● Data are sent in ascending order from low bytes of [S+1] in the table specified by the
GPTRNS / pGPSEND / GPSEND instruction.
● During sending, the general-purpose communication sending flags that correspond to the
connection (Y80 to Y8F) are turned ON. They turn OFF when sending is completed.
● The sending result (0: normal completion; 1: abnormal completion) is stored in the general-
purpose communication sent flags (Y70 to Y7F).
