For identification purposes, each appliance connected must have its own unique IP address.
Each chamber is delivered by default with the IP address 192.168.100.100. The program
“XTADMIN”, which can be found on the CD-ROM provided, can be used to change the IP ad-
dress.
Setting the IP address is described in a separate manual.
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.

For a printout, the GLP header is also printed automatically, and contains the following details:
Ź
Date of printout
Ź
Period of log
Ź
Consecutive page numbers
Ź
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.
