This section describes instructions used to define and handle timers and
counters.
Refresh Methods for Timer/Counter PV
■ Overview
The refresh method for present values timer and counter instructions can be
set to either BCD or binary for CP-series CPU Units.
Using binary data instead of BCD allows the SV range for timers and counter
to be increased from 0 to 9999 to 0 to 65535. It also enables using binary data
calculated with other instructions directly as a timer/counter SV. The refresh
method is valid even when setting an SV indirectly (i.e., using the contents of
memory word). (That is, the contents of the addressed word is taken as either
BCD or binary data according to the refresh method that is set.)
Refer to the CP Series CP1H Operation Manual for details on refresh meth-
ods.
