Process Control Instructions
All operator request inputs are cleared to false at the end of each scan. If
ProgValueReset is true, all program request inputs are cleared to false at the end of
each scan.
Resetting the TOT Instruction
When ProgResetReq transitions to true while ProgOper is true, the following
happens:
•
OldTotal = Total
•
Total = ResetValue
•
ProgResetDone is set to true
If ProgResetReq is false and ProgResetDone is true then ProgResetDone is cleared
to false
When OperResetReq transitions to true while ProgOper is false, the following
happens:
•
OldTotal = Total
•
Total = ResetValue
Calculating the Totalization
When RunStop is true and LowInCutoffFlag is false, the following equation
performs the totalization calculation.
where TimeBase is:
Value Condition
1 TimeBase = 0 (seconds)
60 TimeBase = 1 (minutes)
3600 TimeBase = 2 (hours)
86400 TimeBase = 3 (days)
