Bit information of U area is assigned as the count I/O instruction area and can be set to
specify the count-enabled signal. If the Count Enabled Signal is OFF, the counter does
not operate.
Preset Setting
1.
This can be achieved by first specifying the preset input value and then switching
on Preset Enabled Signal.
2.
Since preset input value is a parameter value, it can be set through I/O Parameters
Write (See Figure 56) and through PUP/PUTP instruction in the scan program (See
Figure 57).
3.
Since Preset Enabled Signal is set through I/O instruction area, the setting method
of %U area address can be used. The following example is used to set the preset
value to 10000.
