7.2.2 Contents of Sent Data
Strings data sent by the GPSEND command are converted into ASCII text and saved in a
given data register.
 Sent data table
• Once the sent data are converted into strings data using the SSET command, the No. of
characters is saved in the header area. The sent data are saved starting with lower bytes of
the subsequent address.
Strings of the No. of bytes specified by GPSEND command
are sent, in ascending order from lower bytes.

KEY POINTS
• No start code or end code are attached to data that are sent from the FP7
CPU unit. When it is necessary to send a start code and an end code in
accordance with the protocol of an external device, save them as a part of
sent data.
• The data size that can be sent in a single transmission based on GPSEND
command from the LAN port of the FP7 CPU unit is up to 16,384 bytes.
