● 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.
● The UNITSEL instruction is used to specify a slot number (LAN port: U100) and the
connection 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).
