11.4 Real-time clock

The real-time clock can be set and read from the controller in two
ways: Unix format or standard format.
All time stamps in the event log and in the data log are also Unix
time format. Read the time with UNIXRealTimeClockHI (register
00228) and UNIXRealTimeClockLO (register 00229), or set a new
time with SetRealTimeClockHI (register 00112) and
SetRealTimeClockLO (register 00113). The new time is activated
in LC 2X1/LC 2X2 when writing the LO-order register. We
recommend writing the HI/LO registers in the same telegram.
11.4.1 Standard format
In the standard format, there are registers for specifying second,
minute, hour, day, month and year (year, offset by 2000) in a
human-readable way. With registers from 00230 to 00235 the
actual values can be read, and with registers 00114 to 00119 new
values can be set. The new values will be activated when writing
the value "1" to SetRtc (register 00120, bit 0).

11.5 Event simulation

It is possible to simulate alarm/warning events by writing
appropriate values to the following registers:
• SimulationEventCode (register 00703)
• SimulationDeviceType (register 00704)
• SimulationDeviceNo (register 00705).
Afterwards it is possible to trigger the simulated event via
SimulationActivate (register 00708, bit 0). The event recording
will take place as if the event was real, but the system operation
will not be influenced.
The SimulationActiveCode (register 00709) can be used to check
if event simulation is active. If the value is 0, there is no active
event simulation.
By clearing the SimulationActivate (register 00708, bit 0) control
bit, the simulated event is cancelled.
Event simulation procedure
• Write a valid event code, see section
block, to SimulationEventCode (register 00703).
register
• Write a device type to SimulationDeviceType (register 00704),
0: system, 6: pump.
• Write a device number to SimulationDeviceNo (register
00705). 1: pump 1, 2: pump 2.
• Activate the alarm simulation with the above settings by
writing 1 to SimulationActivate (register 00708, bit 0).
