3.3 Specifications
(g) Data number for initialization designation area (address 52 (34H))
• The registration number for the initialization data transmitted with the initialization request to the modem on
the Q series C24 side is designated. The registration number for the Q series C24 is used.
• For details on the designation using GX Configurator-SC, refer to Q Corresponding Serial Communication
Module User's Manual (Basic).
An example of designations using the program is shown in Page 144, Section 3.4.5.
(h) Data number for connection designation area (address 53 (35H))
• Designates the registration number of the data for connection used by the Q series C24 for the connection
processing to the partner device in order to perform data communication/notification. The registration
number for the Q series C24 is used.
• For details on the designation using GX Configurator-SC, refer to Q Corresponding Serial Communication
Module User's Manual (Basic).
An example of designations using the program is shown in Page 148, Section 3.4.6.
(i) GX Developer connection designation area (address 54 (36H))
• Whether to access the programmable controller from GX Developer by connecting the Q series C24 and GX
Developer using the Q series C24 modem function is designated.
• When connecting the Q series C24 and GX Developer using the Q series C24 modem function, select "PLC
side I/F = via telephone line connection (Q/A6TEL, C24)" in the "Transfer Setup" screen of GX Developer.
(When connecting direct shown in Page 79, Section 3.2.3). When this GX Developer designation is
performed, designate "1" in this area on the Q series C24 side.
(j) No-communication interval time designation area (address 55 (37H))
• Designates the wait time until the line is closed when the data communication has ceased with the
destination device after the line connection.
• The Q series C24 automatically performs the line disconnection processing when no data communication is
performed with the destination device for a designated time. The connection in progress signal (X12) and the
modem initialization completion signal (X10) turn off and the modem disconnection completion signal (X14)
turns on when the line disconnection processing is performed.
(k) RS/CS control yes/no designation area (address 56 (38H))
• Designates whether to use the RS/CS signals for controls to notify local station-side data reception capability
to the partner side during data transmission between the Q series C24 and modem/TA.
• This setting is for the interface designated by the modem connection channel indicated in Page 110, Section
3.3.6 (2) (a). The control of the other interface that does not use the modem function is performed by the
settings in the buffer memory DTR/DSR and DC control designation area (address: 93H/133H).
