Appendix 1 Periodic Printout and Printout Using the TLOG Timer (/M1 Option)

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.
