6-2-2 Calculation and Selection Processing of Input Data
Input Data Calculation The following types of calculations can be performed in the unit for external
analog input values.
• Scaling to desired industry unit
• Moving average processing
After processing, the data can be allocated to the Master Unit I/O.
In addition, the following types of calculations can be performed for analog
values for which the processing described above was performed.
• Peak/hold operation
• Top/valley operation
• Rate of change operation
• Cumulated count operation
The values after these calculations are called "Peak Value", "Bottom Value",
"Top Value", "Valley Value", "Rate of Change", and "Cumulated Count Value".
