● 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 (Y8, Y9, YA, YB) 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 (Y0, Y1, Y2, Y3).
