PRECAUTIONS FOR
USE OF AnS SERIES
MODULE
(7) Clock setting
If the year exceeds 2100 after the clock setting of the C Controller module, the C
Controller module can be used with the clock data of 2100 or later until it is restarted.
When the C Controller module is restarted, the year will be re-set to 2000 - 2099.
(8) When operation status is changed from RUN to STOP/PAUSE
When the operation status of the C Controller module changes from RUN to STOP/
PAUSE, the user program task does not stop.
Use the QBF_ReadStatusEx function when dividing the user program processings
according to the operation status of the C Controller module.
(9) Application of user watchdog timer
Use the user watchdog timer to check the hardware and user program for runaway
and processing overtime when accessing or controlling each module using the user
program.
(10)When user watchdog timer cannot be reset
A user watchdog timer error will occur if the user watchdog timer cannot be reset due
to user program runaway.
(11)User watchdog timer setting range
Set the user watchdog timer within the range 100ms to 10000ms (10ms units).
(12)Relationships between Tornado, system watchdog timer and user
watchdog timer
When using Browser's Spy Chart function or Wind Power tool (e.g. WindView) in
Tornado environment, set a longer time for the system watchdog timer and user
watchdog timer.
When Browser's Spy Chart function or Wind Power tool (e.g. WindView) is used, a
system watchdog timer error and user watchdog timer error are likely to occur since
the task of high CPU utilization operates.
(13)IP address setting
The IP address of the C Controller module cannot be set from the user program.
Set it on the <<Online operation>> tab of the C Controller setting utility.
