Frequently Asked Questions
Why can’t I see the Use Cache check box in
Device Manager
?
(or another control in the Windows dialog at the bottom of a screen, such as the
progress bar during manual data collection)
The required minimum monitor resolution for Device Manager is 1600 x 900.
How many sensors can the network have?
SKF recommends a maximum of 50 sensors for each gateway for performance
reasons. Because the P+F gateway’s web page user interface slows considerably after
60 to 70 sensors have joined the network,
SKF considers any installation of 50 sensors
or more to be a large system installation.
Note
: Adding gateways will decrease the
number of sensors per gateway and improve the user interface response and network
communication speed.
Can I replace the sensor’s battery?
No. If the battery life is low, contact CSG to return the sensor to SKF for replacing the
battery.
How long will the sensor’s battery last?
The battery should last for several years, but battery life cannot be precisely predicted
and will vary based on the following factors:
•
How often data is taken
•
Leaf node vs. full routing mode
•
External temperature and environmental conditions
•
P1 or P2 profile setting, when available
I get the message “License Key Expired” even though it is not expired.
Either the file has moved – that is, the software was moved to a different computer - or
the software is running a different database.
Can I monitor mobile equipment, such as a crane or forklift, with a CMWA 8800 sensor?
No. The wirelessHART mesh network does not adapt quickly to changing conditions
and therefore does not effectively monitor mobile equipment. When the CMWA 8800 is
