7.6.3 Connecting test chambers to a network with Ethernet interface
The constant climate chamber can optionally be equipped with an Ethernet instead of a USB
interface.
LAN 1: 192.168.1.233
192.168.1.216
LAN 2: 192.168.1.215 LAN 3: 192.168.1.241

(schematic diagram)
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 programme
“ XTADMIN“, which can be found on the “Celsius“ CD-ROM, can be used to change the IP
address.
How the IP address is changed and the oven is logged on is described in the
”Celsius“ manual.
7.6.4 Log memory
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. For documentation purposes the controller
memory can be read out via the Celsius control software. Each dataset is stored with a unique
timestamp.
The internal log memory has a size of 1024 kB. This corresponds to a storage capacity for
about three months in permanent operation.
Since large amounts of data are stored during ramp mode, this can reduce the maximum
logging time.
