■For user frame registration: Registration data byte count designation area (Un\G6912, 6953)
• The initialization data or data for connection can be registered in the buffer memory as well as the flash ROM of C24.
Data type
Initialization data
Data for connection
A registration number to register data for initialization or data for connection to the buffer memory is in the range of -32767 to
-32737 (8001H to 801FH) respectively, which is determined by the area to be used.
• In this area, the number of bytes for the data for initialization or data for connection (for 1 data) to be registered in the buffer
memory is designated.
• For more information on how to register data for initialization or data for connection in the buffer memory, refer to the
following sections.

Buffer memory address
■For user frame registration: User frame specification area (Un\G6913 to 6952, 6954 to 6993 )
• Designate the applicable data (for 1 data) for the above registration data byte count when registering the data for
initialization or data for connection in the buffer memory.
• For more information on how to register data for initialization or data for connection in the buffer memory, refer to the
following sections.

Buffer memory address
■Auto modem initialization designation (Un\G8199)
• Designate whether the modem on the C24 side is initialized automatically or not.
• Registration in this area is performed with Engineering tool.
The modem is initialized automatically when C24 starts up after the CPU module restarts.
■Modem initialization DR (DSR) signal enable/disable designation (Un\G8200)
Set "DR signal enabled" for this setting.
This setting is used to designate how the DR (DSR) signal is treated only when modem initialization is performed. Following
the completion of modem initialization, data is sent according to the status of the DR (DSR) signal.
■Complete signal handling for modem function designation (Un\G8201)
Set "Turn ON/OFF X13, X14" (default value) for this setting.
