A.14.18. Trend and Time Monitoring
TITNA-SVX has a trend monitoring feature which enables monitoring the history
of the power or temperature.
Trend monitoring is useful in detecting any slow creeps or steady increase and
decrease in the system performance. For example, power usage trend is
monitored and a slow steady rise in the power usage for the same repetitive
motion is detected. No fault or sudden change in power or current usage is
detected, but the slow rise in the power usage which may indicate a slow
degradation in the motion system.
The trend processing and monitoring is done inside the TITAN controller and is
available for monitoring by the master controller such as a industrial PC or PLC.
There are 2 types of trend data that can be collected:
1. Power
2. Temperature
There are 4 types of trend storage arrays
1. 60 second data
2. 60 minute data
3. 24 hour data
4. 30 day data
Every data is collected at 100msec interval.
Each second data is calculated by summing the collected ten 100msec data and
dividing by 10.
Every minute data is calculated by summing the previous sixty sets of second
data and dividing by 60.
Every hour data is calculated by summing the previous sixty sets of minute data
and dividing by 60.
Every day data is calculated by summing the previous twenty four hour data and
dividing by 24.
In addition to trend data monitoring, TITAN-SVX has time counter to keep track
of system time, motor run time, and fault trigger time.
All time values are in seconds.
System time starts counting from 0 at initial power on state of the controller.
