9.8 Operation Analysis
[Purpose]
Analyze the PLC CPU operation.
Each item in "Analysis setting" dialog box must be set in advance.
Operation Analysis can be selected from "Order check", "Count check",
"Normal/Fault pattern check", "High/Low limit value check".

condition, detects the error position (if any) as error or warning and displays the
results.
When an operation analysis name is set to each of settings, the analysis can be
executed based on the same settings by selecting the operation analysis name
without the necessity to set the condition for each time.
Multiple operation analysis dialog boxes can be simultaneously started.
