4.1.3 Handling machine data
Handling methods
S Display
S Input via keys and V24 interface
S Making backup copies and reading in/reading out data via the V24 interface
These back–up copies contain
– machine data
– line check sums and
– machine data numbers.
Aborting when loading MD
If incorrect machine data files are read into the control system, an alarm is output.
At the end of reading, an alarm with the number of errors is displayed.
4.1.4 Data saving
Saving data internally
The data in the memory backed up for a limited period can be saved internally in the perma-
nent memory of the control system.
An internal data backup should be carried out if the control system has been switched off for
more than 50 hours (at least 10 min/day with controller ON).
It is recommended to carry out internal data saving whenever important data changes have
been made.
