(3) Details of buffer memory (for the remote password function)
Each of the areas described below is valid when the Q series C24 performs the remote password check.
(a) Remote password mismatch notification count designation area (address 8204
(200CH))
• Use 0 to FFFFH to designate the count that will be the notification timing to the QCPU when a remote
password mismatch occurs during the user/external device unlock processing after the modem line has
been connected.
• It cannot confirm the accumulated number of times a remote password mismatch occurred up to the present
after the line connection.
(b) Remote password mismatch notification accumulated count designation area
(address 8205 (200DH))
• Use 0 to FFFFH to designate the accumulated count that will be the notification timing to the QCPU when a
remote password mismatch occurs during the user/external device unlock processing after the Q series C24
has been started up.
• The accumulated number of times up to the present a remote password mismatch occurred (accumulated
count value in the Q series C24) after starting up can be checked in the area where the accumulated count
of unlock process abnormal completion is stored (address 8956 (22FCH)).
(c) Storage area for accumulated count of unlock process normal completion (address
8955 (22FBH))
The accumulated number of times the remote password unlock process has been completed normally is
stored.
(d) Storage area for accumulated count of unlock process abnormal completion
(address 8956 (22FCH))
The accumulated number of times the remote password unlock process has been completed abnormally is
stored.
(e) Storage area for accumulated count of lock process based on circuit line
disconnection (address 8959 (22FFH))
The accumulated number of times the Q series C24 has automatically performed the lock process due to a
modem line disconnection is stored.
Each of the accumulated count values stored in Page 116, Section 3.3.6 (3) (c) to Page 116, Section 3.3.6 (3) (e) above are
further explained below:
● The user can clear the values using either of the following:
• Set the accumulated count to "0" using the GX Configurator-SC modem function monitor/test screen.
• Write "0" to the applicable area of the buffer memory.
● The accumulated count will be stored as 0H 1H 2H... FFFFH 0H 1H ...
