SPM_Bypass_Verification
“Yes” means that the verification of the baseline is turned off while “No” indicates 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 with the default
set at 15 minutes.
SPM#_Block_Tag
Enter the Block Tag of the function block containing the parameter to be monitored. Block tag
must be entered, since there is no pull-down menu to select the tag. The tag must be a valid
“Block Tag” in the device. The default block tags from the factory are:
 AI 1400
 AI 1500
 PID 1600
 ISEL 1700
 CHAR 1800
 ARITH 1900
SPM can also monitor “out” parameters from other devices. Link the “out” parameter to an
input parameter of a function block residing in the device, and set up SPM to monitor the input
parameter.
SPM#_Block Type
Enter the Block Type of the function block containing the parameter to be monitored.
SPM#_Parameter Index
Enter the Parameter Index of the parameter to be monitored.
SPM#_Thresholds
The SPM#_Thresholds allow alerts to be sent when the values are beyond the threshold values
that set for each parameter.
Mean limit
Alert Limit value in percent change of the Mean compared with the baseline mean value.
High variation
Alert Limit value in percent change of the Stdev compared with the baseline Stdev value.
Low dynamics
Alert Limit value in percent change of the Stdev compared with the baseline Stdev value.
