15.2 GPTRNS / pGPSEND /GPSEND (General-Purpose Communication
● The maximum volume of data that can be sent in a single instance with GPTRNS,
pGPSEND, and GPSEND instructions is 16,384 bytes.
■
Sample program (in the case of SCU)
● This program checks that the general-purpose communication mode is on (X8:ON) and that
general-purpose sending is not in progress in the same port (Y8:OFF), and then starts up the
sending program.
● Using the SSET instruction, convert any given message into an ASCII string. Set the number
of sent characters to the data register DT100, and the sent message to the data register
DT101.
● Using the UNITSEL instruction, specify the slot number (U0) and the COM. port number
(U1).
● In the GPTRNS / pGPSEND / GPSEND instruction, specify and execute the start of the table
that stores the message to be sent (DT101) and the number of characters in the data
(DT100).
