Verify Phase
SPM Configuration
The verifying phase is similar to the learning phase. It calculates a baseline value which is then compared to the learning phase baseline value. This is done to ensure a steady process before the detection phase. The amount of acceptable deviation between the two values is set up in PLINE_Learn_Sensitivity.
Monitoring Phase
The monitoring phase starts after the learning process is complete. The algorithm compares the current values to the baseline values of the mean and standard deviation. During this phase the algorithm computes the percent change in mean and standard deviation to determine if the defined limits are violated.
SPM_Bypass_Verification
If “Yes” the verification of the baseline is turned off. If “No” the learned baseline is compared to the next current calculated value to ensure a good baseline value. The recommended value is NO.
SPM_Monitoring_Cycle
SPM_Monitoring_Cycle is the length of time the process values are taken and used in each calculation. A longer monitoring cycle may provide a more stable mean value. The default is 15 minutes.

SPM can also monitor “out” parameters from other devices. To do this, link the “out” parameter to an input parameter of a function block that resides in the device, and set up SPM to monitor the input parameter.
