Numerical Calculation
Specific substitution function
When a specific substitution is specified, the numerical calculations are only executed
when there is a specific start signal for the parallel or serial signal. "ER" is displayed if
an error occurs during calculation or if the value of a checker that has not be set is
specified.
Example:
CA01 ! GE01011
CA02 = CA01 – GE02011
If numerical calculations are set as shown above, then as can
be seen from the timing chart below, the CA02 calculation is
not executed when there is no ACK signal input from the
parallel input.
When the specific substitution flag is off, the calculation is not
executed and the previous value is retained.
READY output: /READY
START input: /START
/ACK
Specific substitution
Whether or not the specific substitution calculation is
executed is determined by whether or not the ACK signal
remains ON from before the START signal is received until the
READY signal goes OFF.
Setup is possible when setting numerical calculation
programmes regardless of whether the ACK signal is ON or
OFF.
Specific substitution can also be executed from the serial
interface with the %P command.
Note
Even when the specific substitution is executed, it is not written
to the F−ROM.
