Controlling and usage of the data logger
The “data logger’ is controlled / configured by OMC-Programmer. Through this program, you can control
the OMC-045-II if it is working and read the actual values of the sensors. You need an USB connection
between the OMC-045-II and the PC for this.
You can perform the following tasks:
Configure
Updating
Firmware
Check the GSM signal strength
Check the GPS location
Check the actual values
Communicating with the serial port, if necessary

Help with using OMC-programmer, can be found in the Manual and in the help files (via function key
[F1]).
6.1 The data logger
The OMC-045-II uses a scheduler to plan all his tasks and run the
tasks in a periodical time. These tasks are controlled by the task
manager. The task manager keeps track of every status of all tasks.
The task manager knows when a certain task has to be executed, by
means of a task timer. Furthermore the task manager knows how
many times a task preformed a timeout and which “power switch” they
use.
6.1.1 Power Delay
As soon as the task timer of an input task gets in its power delay
time, the used “power switch” of that input task is activated. A
power delay is a period between the activation of a sensor and
when the data is trustworthy enough to be read. This can be
warming up time for analog sensor. There is a power delay for
every switched Voltage output.
