ENT
Creates a 0.1-s decrementing timer that starts from the
set value (SV: 0.1 to 25.0 s) when the execution
condition turns ON. Not all timer/counter instruction
require input of the SV. Here it is adjusted with a
manual adjustment on the PC.

SV
Creates a high-speed incrementing counter. The
present value (PV) will be incremented by one
whenever CP goes from OFF to ON as long as the
start input (SI) is ON and the reset input (R) is OFF.
The Completion Flag, CNT 13, is turned ON when the
PV reaches the SV and will remain ON for one scan
only. The PV is automatically reset to zero when the
SV is reached. The SV can be between 0000 and
9999; setting 0000 creates an SV of 10,000.

RD
Creates a decrementing timer that starts from the set
value determined by the #1 analog timer adjustment on
the front of the CPU. If RD=0000, the SV ranges from
1 to 250 s. If RD=0001, the SV ranges from 0.1 to
25.0 s. If RD=0002, the SV ranges from 0.01 to 2.50 s.
The SV can be input only via the hardware adjustment.
