Important point
1) Write of a constant to a timer/counter:
Even if "0" is written to the current value or set value of a timer/counter, the output contact in
the PLC is not reset. (Though the current value or set value becomes 0, the output contact
does not become OFF.)
To reset a timer/counter, execute an RST instruction in the sequence program or reset the
timer/counter using a bit function.
2) Constant write condition
"
$
" indicates that write of constant is enabled.
