Device definition - Counters view parameters

The Counters
view in Device definition
includes these parameters.

Parameter	Description
Mode	Defines the operating mode of the counter. There are two counters. Available options are: Count/External Direction - The B input controls the direction of the counter. If the B input is low, that is 0, the counter increments on the rising edges of input A. If the B input is high, that is 1, the counter decrements on the rising edges of input A. Count/Internal Direction - The status of InvertDirectionInput determines the direction of the counter. The counter increments on the rising edge of the device’s A input when InputDirectionInput is reset, that is, equals 0. The counter decrements on the rising edge of the A input when InputDirectionInput is set to 1. Up/Down Pulses - The counter channel increments on the rising edge of pulses that are applied to input A and decrements on the rising edge of pulses that are applied to input B. Quadrature X1 - When a quadrature encoder is attached to inputs A and B, the phase relation of inputs A and B determine the count direction. If input A leads input B, the counter increments. If input B leads input A, the counter decrements. Quadrature X2 - Operates much like the X1 Quadrature Encoder except that the resolution is doubled. Quadrature X4 - Operates much like the X1 Quadrature Encoder except that the resolution is quadrupled.
Z Terminal Function	Defines the terminal function that is used with the counter mode. Available options are: Reset Reset, Store Reset, Hold Reset, Store, Hold Load Load, Store Load, Hold Load, Store, Hold Store, Hold Store Hold Not used

Parameter

Description

Mode

Defines the operating mode of the counter. There are two counters. Available options are:

Count/External Direction
- The B input controls the direction of the counter. If the B input is low, that is 0, the counter increments on the rising edges of input A. If the B input is high, that is 1, the counter decrements on the rising edges of input A.

Count/Internal Direction
- The status of InvertDirectionInput determines the direction of the counter. The counter increments on the rising edge of the device’s A input when InputDirectionInput is reset, that is, equals 0. The counter decrements on the rising edge of the A input when InputDirectionInput is set to 1.

Up/Down Pulses
- The counter channel increments on the rising edge of pulses that are applied to input A and decrements on the rising edge of pulses that are applied to input B.

Quadrature X1
- When a quadrature encoder is attached to inputs A and B, the phase relation of inputs A and B determine the count direction. If input A leads input B, the counter increments. If input B leads input A, the counter decrements.

Quadrature X2
- Operates much like the X1 Quadrature Encoder except that the resolution is doubled.

Quadrature X4
- Operates much like the X1 Quadrature Encoder except that the resolution is quadrupled.
