Timer Logic Commands

Overview

The custom logic editor uses the following timer commands:

TIMER_SEC
TIMER_TENTHS
TIMER_K_SEC
TIMER_K_TENTHS

NOTE: When a custom logic file is uploaded to the simulator and a timer is enabled, it will function as expected. However, once a timer has been enabled and executed, it cannot be enabled again. This is a limitation of the TIMER_SEC and TIMER_TENTHS. To enable the timer again, the custom logic file should be uploaded again. It is recommend that this limitation is considered when designing and testing the custom logic files when working with timers.

TIMER_SEC

The TIMER_SEC command:

Counts time in seconds, up to the number of counts specified by a temporary register
Calculates the end time in a second temporary register
Is enabled by, and reports its counting status to, a third temporary register

Arguments	Representation
3	`TIMER_SEC TmpReg1 TmpReg2 TmpReg3`

Input Argument	Type	Range/Bit	Description
`TmpReg1`	`UINT`	0–65,535	Timer preset value
`TmpReg3`	`UINT`	Bit0	Starts the timer on a rising edge Stops the timer on a falling edge

Output Argument	Type	Range/Bit	Description
`TmpReg2`	`UINT`	0–65,535	Calculated end time
`TmpReg3`	`UINT`	Bit1	Timer done: Bit set when timer reaches `TmpReg2` Bit reset when: `TmpReg3.Bit0` is reset Power is cycled
		Bit2	Timer execution in progress Bit reset when timer reaches `TmpReg2`
		Bit3	`TmpReg3.Bit0` history bit
		Bit4	Reserved

TIMER_TENTHS

The TIMER_TENTHS command:

Counts time in tenths of seconds, up to the number of counts specified by a temporary register
Calculates the end time in a second temporary register
Is enabled by, and reports its counting status to, a third temporary register

NOTE: The multiplication factor for the TIMER_TENTHS command is 10. For example, if the required value is 6 seconds, the input value should be multiplied by a factor of 10, meaning the input value provided should be 60 seconds.

Arguments	Representation
3	`TIMER_TENTHS TmpReg1 TmpReg2 TmpReg3`

Input Argument	Type	Range/Bit	Description
`TmpReg1`	`UINT`	0–65,535	Timer preset value
`TmpReg3`	`UINT`	Bit0	Starts the timer on a rising edge Stops the timer on a falling edge

Output Argument	Type	Range/Bit	Description
`TmpReg2`	`UINT`	0–65,535	Calculated end time
`TmpReg3`	`UINT`	Bit1	Timer done: Bit set when timer reaches `TmpReg2` Bit reset when: `TmpReg3.Bit0` is reset Power is cycled
		Bit2	Timer execution in progress Bit reset when timer reaches `TmpReg2`
		Bit3	`TmpReg3.Bit0` history bit
		Bit4	Reserved

TIMER_K_SEC

The TIMER_K_SEC command:

Counts time in seconds, up to the number of counts specified by a constant value
Calculates the end time in a temporary register
Is enabled by, and reports its counting status to, a second temporary register

Arguments	Representation
3	`TIMER_K_SEC KValue TmpReg1 TmpReg2`

Input Argument	Type	Range/Bit	Description
`KValue`	`UINT`	0–65,535	Timer preset value
`TmpReg2`	`UINT`	Bit0	Starts the timer on a rising edge Stops the timer on a falling edge

Output Argument	Type	Range/Bit	Description
`TmpReg1`	`UINT`	0–65,535	Calculated end time
`TmpReg2`	`UINT`	Bit1	Timer done: Bit set when timer reaches `TmpReg1` Bit reset when: `TmpReg2.Bit0` is reset Power is cycled
		Bit2	Timer execution in progress Bit reset when timer reaches `TmpReg1`
		Bit3	`TmpReg2.Bit0` history bit
		Bit4	Reserved

TIMER_K_TENTHS

The TIMER_K_TENTHS command:

Counts time in tenths of seconds, up to the number of counts specified by a constant value
Calculates the end time in a temporary register
Is enabled by, and reports its counting status to, a second temporary register

Arguments	Representation
3	`TIMER_K_TENTHS KValue TmpReg1 TmpReg2`

Input Argument	Type	Range/Bit	Description
`KValue`	`UINT`	0–65,535	Timer preset value
`TmpReg2`	`UINT`	Bit0	Starts the timer on a rising edge Stops the timer on a falling edge

Output Argument	Type	Range/Bit	Description
`TmpReg1`	`UINT`	0–65,535	Calculated end time
`TmpReg2`	`UINT`	Bit1	Timer done: Bit set when timer reaches `TmpReg1` Bit reset when: `TmpReg2.Bit0` is reset Power is cycled
		Bit2	Timer execution in progress Bit reset when timer reaches `TmpReg1`
		Bit3	`TmpReg2.Bit0` history bit
		Bit4	Reserved
