■Line disconnection wait time (for PLC CPU monitor) (Un\G8206)
• When transmitting data using the programmable controller CPU monitoring function, designate the time between data
transmission from C24 and completion of data transmission from the modem on the host station side to the target device
side (wait time to disconnect the line).
• Specify the line disconnection wait time in accordance with the specifications of the modem to be used.
Details of buffer memory (for the remote password function)
Each of the areas described below is valid when C24 performs the remote password check.
■Remote password mismatch notification count designation (Un\G8204)
• Designate the count that will be the timing to notify the CPU module that a remote password mismatch occurred during the
unlock processing by the user/target device after the modem line has been connected with 0 to FFFFH.
• Confirming the accumulated number of times of occurred remote password mismatch up to the present time after the line
connection is not available.
■Remote password mismatch notification accumulated count designation (Un\G8205)
• Designate the accumulated count that will be the timing to notify the CPU module that a remote password mismatch
occurred during the unlock processing by the user/target device after C24 has been started up with 0 to FFFFH.
• The accumulated number of times remote password mismatch occurred up to the present time from C24 startup
(accumulated count value by C24) can be checked in the 'Accumulated count of unlock process abnormal completion'
(Un\G8956).
■Accumulated count of unlock process normal completion (Un\G8955)
The accumulated number of times the remote password unlock process has been completed normally is stored.
■Accumulated count of unlock process abnormal completion (Un\G8956)
The accumulated number of times the remote password unlock process has been completed abnormally is stored.
■Accumulated count of lock process by line disconnection (Un\G8959)
The accumulated number of times C24 has automatically performed the lock processing due to a modem line disconnection is
stored.
The supplemental information for each of the accumulated count stored in Un\G8955, 8956, and 8959 is
shown below:
• The value can be cleared by writing "0" to the corresponding area of the buffer memory.
• The accumulated count will be stored as 0H  1H  2H   FFFFH  0H  1H  .
