Counter Logic Commands

Overview

The custom logic editor uses the following counter logic commands:

COUNTER
COUNTER_NV

COUNTER

The COUNTER command:

Increments or decrements a count value
Provides a method for setting the count value to a preset value
Indicates when the count value equals 0
Indicates the relationship between the count value and the preset value - equal to, greater than or less than
Saves the increment, decrement and set status from the previous scan

Arguments	Representation
3	`COUNTER TmpReg1 KValue TmpReg2`

Input Argument	Type	Range/Bit	Description
`KValue`	`UINT`	0–65,535	Counter preset value
`TmpReg2`	`UINT`	Bit4	Increments the counter current value on a rising edge. Counter current value shall roll over from 0 to 65,535.
		Bit5	Decrements the counter current value on a falling edge. Counter current value shall roll over from 65,535 to 0.
		Bit6	Sets the current counter value to the preset value on a rising edge

Output Argument	Type	Range/Bit	Description
`TmpReg1`	`UINT`	0–65,535	Counter current value
`TmpReg2`	`UINT`	Bit0	The counter current value is 0: `TmpReg1=0`
		Bit1	The counter current value is lower than the preset value: `TmpReg1<KValue`
		Bit2	The counter current value is equal to the preset value: `TmpReg1=KValue`
		Bit3	The counter current value is greater than the preset value: `TmpReg1>KValue`
		Bit7	`TmpReg2.Bit4` history bit
		Bit8	`TmpReg2.Bit5` history bit
		Bit9	`TmpReg2.Bit6` history bit

COUNTER_NV

The COUNTER_NV command:

Increments or decrements a count value
Provides a method for setting the count value to a preset value
Indicates when the count value equals 0
Indicates the relationship between the count value and the preset value - equal to, greater than or less than
Saves the increment, decrement and set status from the previous scan

Use the COUNTER_NV command, instead of the COUNTER command, to retain the count during a power cycle.

Arguments	Representation
3	`COUNTER NVReg1 KValue NVReg2`

Input Argument	Type	Range/Bit	Description
`KValue`	`UINT`	0–65,535	Counter preset value
`NVReg2`	`UINT`	Bit4	Increments the counter current value on a rising edge. Counter current value shall roll over from 0 to 65,535.
		Bit5	Decrements the counter current value on a falling edge. Counter current value shall roll over from 65,535 to 0.
		Bit6	Sets the current counter value to the preset value on a rising edge

Output Argument	Type	Range/Bit	Description
`NVReg1`	`UINT`	0–65,535	Counter current value
`NVReg2`	`UINT`	Bit0	The counter current value is 0: `NVReg1=0`
		Bit1	The counter current value is lower than the preset value: `NVReg1<KValue`
		Bit2	The counter current value is equal to the preset value: `NVReg1=KValue`
		Bit3	The counter current value is greater than the preset value: `NVReg1>KValue`
		Bit7	`NVReg2.Bit4` history bit
		Bit8	`NVReg2.Bit5` history bit
		Bit9	`NVReg2.Bit6` history bit
