Pulse_TargetValueMatch_SetTarget value match ON (pulse output)
If the elapsed value matches the target value diTargetValue of the pulse output channel specified by iChannel, the output relay specified by pYOutput immediately turns to TRUE.
Input
A rising edge activates the function; evaluate the pulse output channel control flag using PulseInfo_IsTargetValueMatchActive

Pointer result obtained by GetPointer from a global variable that supplies the channel number and output
Specify a 32-bit data value for the target value within the following range:
FP0, FP-e: -838808–+8388607
FPS, FP-X, FP0R: -2147483467–+2147483648
Output
TRUE if the combination of Channel%d and pYOuput.iOffset does not match a valid combination of channel number and output as determined by the global variable
This non-inline instruction is part of the tool instructions for pulse output. For a detailed description of the instruction(s) used internally, please refer to:F166_PulseOutput_Set
To validate the combination of channel and Y output, the compiler requires the following name pattern for global variables:%sPulse_TargetValueMatch_Channel%d_Y%d_%s
Always use this pattern for global variables in target value match control.
Channel%d must be a pulse output channel number enabled in the system registers
Y%d must be an explicit output address supported by the PLC

This global variable generates the code for channel A and output Y11F.
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.

END_VARUse PulseInfo_IsTargetValueMatchActive to evaluate the channel iChannel1 is active. If a rising edge is detected at bSet and if bIsActive is not TRUE, the instruction is executed. The combination of channel number and output contact is validated in the global variable g_bPulse_TargetValueMatch_Channel1_YA_Horn1_On. When pulse output on channel 1 reaches the target value diTargetValue0, output YA is set to TRUE.
