Data memory (056)
Measured values and events are available in 4
defined profiles for storage. Each of the 4
memory profiles can be selected individually or
together with other profiles.
Memory
In UMG96S is always an EEPROM memory in-
cluded to store the configuration data and mini-
mum and maximum values. Optionally, a data
memory (FLASH memory) is available for stor-
age of measured values and events. Both
memories do not need a battery for storage.
Data memory (Option)
Measured values and events can be stored with
date and time within the memory. If the memory
is full, the most obsolete data are overwritten.
The memory starts with address 500. Up to
32768 data blocks with 18 byte can be stored.
After net breakdown (L1, L2 and L3 fail simulta-
neously) the last 45 seconds can get lost.
Data block
1 Block consists of:
2 Byte Data number
4 Byte time stamp
10 Byte Data string
1 Byte Profile number
1 Byte Error information
Time stamp
In the time stamp, the number of seconds since
1.1.1970 up to the time of storage are counted.
Data string
In the data string, the data of one of the 4 possi-
ble profiles are deposited. A data string may
contain several measured values. In the stored
measured values, the set current and voltage
transformer ratio is not respected.
Profile number
In the profile number is the memory profile,
which is stored in the data string.
Error information
If the storage of data was interrupted by a net
breakdown (L1, L2 and L3 fail simultaneously),
it will be mentioned within the error information.
Byte = 0 The data are o.k.
Byte <> 0 The stored data are wrong.
After the net return and after the set averaging
time, the selected profiles will be stored in the
memory.
The time of storage for memory profile 1 can be
synchronized by a digital input (Option) addition-
ally. Changing the input signal from 0 to 1, the
memory profile will be stored. The time of the
next storage is determined by the averaging
time P.
