7.3 Diagnostics via data sets

7.3 Diagnostics via data sets
Process data consists of analog and digital values, which are obtained from a technical
process by means of sensors. Process data represents the current state of the process in
control technology. Process data is displayed to the operator and then archived, and is used
to automatically influence the process (see Process image (Page 132)).
Logbook entries
The following logbook entries are stored in the starter and can be read out via
"Motor Starter ES", Version 2007 SP2 and higher:
● Device errors DS 72 (Page 197)
● Triggering operations DS 73 (Page 198)
● Events DS 75 (Page 199)
The 3 logbooks are organized as ring buffers of 126 bytes each. The entries are made
together with the current device operating hours in each case. Six bytes are requried per
entry, so that the last 21 entries remain readable in each case.
Format of the entries:
Byte
0 ... 3
4 ... 5
Measured values (DS 94)
The current operating state of the motor can be read from the measured values. Measured
values are volatile variables.
The following data is stored in data set 94 (Page 205) of the motor starter:
● Remaining motor cooling time
● Motor heating
● Asymmetry
● Phase current I
● Phase current I
● Phase current I
● Phase current I
● Phase current I
● Phase current I
● Remaining time for tripping for thermal motor model
● Heat sink temperature (only on sDSSte/sRSSte 12 A)
● Line and output frequency (only on sDSSte and sRSSte)
