Advanced functions
7.8 Log memory
(only for models with communication or premium modules)
The controller continually logs all relevant measured values, settings and error messages at
1-minute intervals.
The internal log memory is listed as a ring memory, i. e. the oldest log data are always over-
written automatically with new data.
The logging function cannot be switched off, but is always active. The measured data are
stored in the controller, safe from manipulation. Each dataset is stored with a unique times-
tamp.
The internal log memory has a size of 1024 kB. This corresponds to a storage capacity for
about three months in permanent operation.
If the power supply is interrupted, the time of the power cut and the return of voltage are
stored in the controller.
Reading in the log memory to the PC via USB interface
For documentation purposes, log data can be read out via an interface.
The log memory of the controller is not modified or deleted by the reading out.
Printing out log memory
(see also Chapter “ Printer “ on page 45 )
For a printout, the GLP header is also printed automatically, and contains the following details:
► Date of printout
► Period of log
► Consecutive page numbers
► Serial numbers and appliance name
If the printer is not ready (e. g. ink cartridge or paper tray empty), no log data will be
lost. Multiple printouts can also be made, since the log memory is not deleted after print-
ing.
