Chapter 4 System Configuration
Data Logger
The WISE-4000 series supports data log functions, the I/O status can be logged in
the module and also be queried from the module.
– Time & Date / SNTP
Before you start the log function, confirm the RTC time inside the WISE module is
configured to the correct time. Standard WISE modules, not including the WISE-
4012E, come with an RTC battery. Once the RTC time has been configured, you
don't need to synchronize the time with SNTP server. The time will be kept in the
RTC with the battery. For the WISE-4012E, which doesn't have an RTC battery, you
need to synchronize the time with the SNTP server.
– Data Configuration
I/O Data
You can configure the Log Conditions to be logged by time period or by communi-
cation with WDT. If you check the By Period box, it enables periodic logging, and the
log period can be decided in following box. Note that the period is increased by 0.1
seconds, meaning that if the user configures “600” here, the status of the I/O will be
logged each minute. If you check the box By Communication WDT, it will been
enabled, once the condition of the WDT has been met, the status of the I/O will be
logged.
For the analog input channel, data can be logged by the AI Deviation Rate (Dividing
difference between present sample value and previous sample value by the total
range value). Here you can enter the percentage of deviation rate to be the criteria
for triggering logger.
All the data can be kept even if the module is powered off, however, you can clear all
data in the logger when powering up WISE module. Just check the Clear Log when
Power Up box. When the data is logged to maximum memory capacity, logger will
stop logging by default. You can check the box of the Circular Log when Memory
Full to overwrite the earliest data.
The Channel Fields tab is to decide which I/O channel's status will be logged, and if
the change of the status also need to be logged or not. Note that the log memory will
be cleared once any parameter is changed in the Channel Fields, and also in IO
Fields.
For a digital channel, check the Log Enabled box to log the status of checked chan-
nel periodically. Or check the Change of State to trigger data logged by status
change. For the universal input channel, the DI channel should be configured in AI/UI
page.
