■
Input value increment operation processing
In input value increment operation processing, the following processing is performed for the input value (E1).
■
Integration value calculation processing
In integrated value calculation processing, the following processing is performed for the input value increment (T1).
*1 In the case of integration stop/reset (e1 = 0), processing is performed by assuming it as integration hold clear (e2 = 0).
■ Output conversion processing
In output conversion processing, the following processing is performed for the integrated values (T2, T3).
