Verify Phase

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#_Block_Tag

Enter the Block Tag of the function block that contains the parameter to be monitored. Block tag must be entered, there is no pull-down menu to select the tag. The tag must be a valid “Block Tag” that is in the device. The default block tags from the factory are:

AI 1400	ARITH 1900
AI 1500	INTEG 2000
AI 2100	AO2700
AI 2200	AO2800
PID 1600	OSPL2600
ISEL 1700	CSEL2500
ISEL 2400	Mass Flow 2900
CHAR 1800

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.

SPM#_Block Type

Enter the Block Type of the function block that contains the parameter to be monitored.

SPM#_Parameter Index

Enter the Parameter Index of the parameter to be monitored.
