ProData II
Clock
The internal device clock is recorded in UTC (Universal
Time Coordinated) format with a resolution of 1 second
and converted into the local time via a possible
configuration of the time zone and the switch between
daylight saving time and standard time.
The time can be read and set via a Modbus address.
The GridVis software can be used as a user-friendly way
to set the clock.
A minute or hour synchronisation of the time takes place
via digital input 9.
Example:
When synchronising the time via Ethernet (NTP),
the external clock is only set and is read during a restart.
The NTP service can receive broadcasts (passive) or
send queries to an NTP server (active). In active mode,
an NTP server with the IP address must be set. A name
resolution is not possible.

Timer
In the ProData 2, 64 independent weekly timers can be
set; here, the resolution is 1 minute. The weekly timer
defines an active period within a day; the active day
must be released within a week.
Example of an active period:
From 9:25 to 11:45 am Sunday, Monday and Friday
The weekly timers can be configured as tariff converters
(1..8), setting digital outputs 1-3, but also as "inoperable".
The status can always be queried via the Modbus.
The states of the timer are linked via an OR operator to
the digital output.
The weekly timer must be set using the GridVis software.
