Target value match OFF (pulse output)
If the elapsed value matches the target value of the pulse output channel, the specified output immediately turns to FALSE.
Input
Pulse output channel: 0–3
specify a 32-bit data value for the target value within the following range: -2147483467 to +2147483648
Output
output which turns to FALSE when the elapsed value matches the target value: Y0–Y1F
Pulse output characteristics
Target value: -200
Elapsed value of pulse output
Execution condition
"Output control active" flag
PLC output
The PLC output turns to FALSE when the elapsed value matches the target value.In addition, the "Output control active" flag turns to FALSE and the instruction is deactivated.If an output is specified that has not been implemented, only the internal memory of the corresponding WY address is set or reset.
Interrupt operation
The interrupt program will be executed when the elapsed value matches the target value. Any interrupt that has been entered into the Tasks list is automatically enabled.A special interrupt program number is assigned to each channel number.

Set "Pulse output" for the desired channel in the system registers.
When this instruction is executed, the "Output control active" flag (e.g. sys_bIsPulseChannel0ControlActive) for the channel used turns to TRUE. No other high-speed counter instruction with output control (F166_PulseOutput_Set or F167_PulseOutput_Reset) using the same channel can be executed as long as this flag is TRUE.
This instruction is available for all pulse output instructions except F173_PulseOutput_PWM and can be executed before or after execution of a pulse output instruction.
The duplicate use of an output in other instructions (OUT, SET, RST, KEEP and other F instructions) is not verified by FPWIN Pro and will not be detected.
To cancel execution of a pulse output instruction, set bit 2 of the data register storing the pulse output control code (sys_wHscOrPulseControlCode) to TRUE. The pulse output control flag will then change to FALSE. To reenable execution of the instruction, reset bit 2 to FALSE.
If both the main program and the interrupt program contain code for the same channel, make sure both are not executed simultaneously.
We strongly recommend that you incorporate aforced stop option in your positioning program.
The status of the high-speed counter control flag or pulse output control flag may change while a scan is being carried out. For example, if the number of received bytes is read more than once different statuses may exist within one scan.
In the global variable list you define variables that can be accessed by all POUs in the project.
All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.
