■ Transferring the current counter value to data memory (DM)
Coding
Description
In step
a)
, the C010 current value is transferred via the internal register and stored
into DM0000, throughout the operation.
■ Transferring the contents of data memory as a setting value for a timer
Coding
Description
•
In step
a)
, contents of DM0010 is transferred to T002 via the internal register for
use as the T002 preset value, when 0002 is ON.
•
In step
b)
, contents of DM0011 is transferred to T002 via the internal register for
use as the T002 preset value, when 0002 is OFF.
•
Although the preset value of T002 is #00010 in the above example, any value
except #00000 can be given because the preset value is changed to the speci-
fied value by turning ON/OFF 0002. Once the counter value has been changed,
the changed value will be stored until it is changed again.
•
The setting values of timers and counters are reset to the original setting values
after the power is turned OFF once and then ON again.
Note 1: If an STA instruction is executed when the current value is larger than the
preset value, the current value will be changed to the preset value.
Note 2: Do not change the setting value of T002 to "#00000".
The C010 current value is transferred to DM0000.
