Configuration
4.10.5 SPM configuration
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.
SPM_Active
SPM_Active parameter that starts the SPM when “Enabled”. “Disabled” turns the diagnostic monitoring
off. It must be set to “Disabled” for configuration, and only set to “Enabled” after fully configuring the
SPM.
