Periodic Printout and Printout Using the TLOG Timer (/M1 Option)
App
Special Cases
This section explains the operation of the periodic printout report (statistical calculation)
and the TLOG computation for special cases. In the explanation below, statistical
calculation represents computation in periodic printout report mode or TLOG
computation.
Operation during Power Failures
If a power failure occurs in the middle of statistical calculation, the operation is as follows
when the power recovers.
The statistical calculation resumes when the power recovers. The exact operation will
vary depending on whether the power is restored before or after the printout time.
Time of Recovery Statistical Calculation Operation
After the printout time Statistical calculation data is created immediately after power is
restored. The measured/computed data up to the time of the power
failure is used. At the next printout time, data after the power recovery
is used to create the statistical calculation data.
Before the printout time The data is created at the printout time after the power recovers. The
measured/computed data excluding the power failure period is used.
Procedure of Handling “Over” Values during Periodic Printout
When an “over” value * is input for sum or average computation, that value is not used in
the computation.
* An “over” value on a measurement channel refers to +Over or –Over. See section 12.4. An
“over” value on a computation channel refers to a value that is less than or equal to
–100000000 or greater than or equal to 100000000 excluding the decimal.
