3.3 Specifications
(u) For user frame registration: User frame designation area (address 6913 to 6952,
6954 to 6993... (1B01H to 1B28H, 1B2AH to 1B51H...))
• When registering the initialization data or data for connection to the buffer memory, the number of
registration data bytes (for 1 data) is designated.
• The registration of data for initialization is described in Page 134, Section 3.4.3. The registration of data for
connection is described in Page 139, Section 3.4.4.
(v) Auto modem initialization designation area (Address 8199 (2007H)
• This designates whether the Q Series C24 side modem is initialized automatically or not.
• Registration of this area is done through the GX Configurator-SC. The modem is initialized automatically
when the Q Series C24 starts up after the QCPU restarts.
(w) DR (DSR) signal valid/invalid designation area during modem initialization (address
8200 (2008H))
Set this setting to "DR signal valid."
*1
*1 This setting is used to designate how the DR (DSR) signal is treated when only modem initialization is performed.
Following the completion of modem initialization, data is sent according to the status of the DR (DSR) signal.
(x) Modem function completed signal handling designation area (address 8201 (2009H))
Set this setting to "turn ON/OFF X13 to X16" (default value).
(y) Wait time of notification designation area (address 8202 (200AH))
• Designates the waiting time from the moment the present notification is executed until the next notification is
executed (Unit: s), when performing more than one notification continuously. (Unit: s)
• Designates wait time of notification after checking the time required during debugging.
(z) Circuit disconnect wait time designation area (programmable controller CPU watch
use) (address 8206 (200EH))
• When sending data using the programmable controller CPU monitoring function, designates the time it takes
to complete data transmission from the local station side modem to the external device after data
transmission from the Q series C24 (wait time until the circuit is disconnected).
• Specify the circuit disconnect wait time to match the specifications of the modem that is being used.
