Panasonic FP0R - Time Constant Processing; Input Time Constant Setting Function and Applicable Models

10-6
10.3 Time Constant Processing
The input time constants for 16 points of the CPU input X0 to XF can be set by the system registers 430
to 433.
If this setting is specified, an operation like the equivalent circuit below will be performed.
By the setting, the noises or chattering of input will be removed.
CXn = Input signal of Xn contact
Xn = Image memory of input Xn
Note:
-
-
If the partial update instruction is executed for the input in the time constant processing, the time
constant processing will be invalid, and the input status at the time will be read out and set.
The input signal of X contact is retrieved at the timing of the normal I/O update.
- The time constant processing can be performed for the input other than X0 to XF (add-on cassettes or
expansion units) by the F182 (FILTR) instruction.
- The timer instruction is not used for the timer processing in this equivalent circuit.
- The time constant processing is invalid when the high-speed counter, pulse catch or interrupt has been
specified.
