Function List
The following table shows the functions of the QD63P6.
I/O numbers (X/Y) and buffer memory addresses in Description describe only for channel
1.
For I/O numbers (X/Y) and buffer memory addresses from channels 2 to 6, refer to Section
3.3.1.
* The functions can be used in combination.
However, when using the linear counter function or ring counter function, select either of them.
Table 3.3 Function list of the QD63P6
Function
Description
Reference
Linear counter function
Countable from -2147483648 to 2147483647 and
detects an overflow when the count range is overrun.
Ring counter function
Repeats count between the ring counter upper limit
value (Un\G2 and 3) and ring counter lower limit value
(Un\G0 and 1).
Coincidence detection function
Presets the coincidence detection point of an arbitrary
channel, compares the detection point to the present
counter value, and outputs the counter value
coincidence (X02).
Coincidence detection
interrupt function
Inputs the interrupt signal to the programmable controller
CPU when a coincidence is detected, and starts an
interrupt program.
Preset function
Rewrites the present counter value to an arbitrary value.
Executes the preset with the sequence program.
Periodic pulse counter function
Stores the present value A (Un\G10 and 11)/present
value B (Un\G200 and 201) in the buffer memory at
every preset period while the periodic pulse counter start
command (Y05) is input.
