What is ETHERLINE
®
GUARD?
ETHERLINE
®
GUARD is a stationary monitoring device that evaluates the current status of a data line
and indicates it as a percentage. This is based on data determined from the physical properties of the
data transmission.
What exactly is the determined "cable condition"?
The real-time display of the cable condition makes it possible to recognise the wear limit of a cable and to
plan the optimal replacement time in advance.
It is a value for the performance condition of the cable
determined from several measured variables. This is indicated in 100% to 20%; below 20%, reliable
conclusions about the functionality of the cable are no longer possible.
How does the measurement of the condition of the pipe work?
The output of the "cable status" is based on an algorithm which collects, converts and continuously
evaluates measured values from various physical transmission parameters as raw values. The raw
values consist, for example, of protocol-related transmission parameters and/or a quality indicator, which
can be calculated from a statistic of the level values.
The "user data" (data transmission) are neither influenced nor evaluated. If a teach-in is carried out, the
line is calibrated, and limit values are set according to the parameters. If these limit values are violated
during operation, correction values flow into the algorithm.
It is important that the algorithm includes historical values. This leads to the following consequence: If a
line is subjected to such mechanical stress (far above the specifications) that it cannot physically "age",
the "prediction" may be delayed. Example: if the data cable is cut with a side cutter, the cable "ages"
abruptly; logically, no "prediction" can take place in advance.
What exactly does the "cable status" say?
The "cable status" is a quality value of the transmission properties of the data line on the GUARD DATA
socket including the connectors. The classification of the areas is based on the model of a traffic light:
Green area = cable / transmission properties are OK. Yellow area = maintenance/replacement required.
Red area = line defective.
How do customers benefit from using ETHERLINE
®
GUARD?
In highly dynamic, demanding movements with high speeds and strong torsion, it is advantageous and
cost-saving if the connection systems are monitored to avoid unforeseen downtimes and thus an
impairment of productivity. ETHERLINE
®
GUARD determines the condition of a data line and indicates
the performance in percent. If the performance falls below a certain value, the device sounds an alarm
and the line must be checked or replaced if necessary.
What can ETHERLINE
®
GUARD do?
ETHERLINE
®
GUARD determines the current performance of a data line from various measured
variables and indicates this as a percentage.
The scope of analysis of ETHERLINE
®
GUARD is
deliberately reduced and monitors a data line and indicates its functionality. This makes it possible to
better plan maintenance work.
For which industry is ETHERLINE
®
GUARD suitable?
ETHERLINE
®
GUARD can be used wherever data cables are used. Especially in moving applications
with high speeds and strong torsion. Such applications are often found in (intra-)logistics, the automotive
sector and medical technology. In principle, however, it is suitable for a wide range of industries.
