WinCC VBScript Example

Dim temp

temp = HMIRuntime.Tags("Tank_Temperature").Read

If temp > 90 Then
    HMIRuntime.Tags("HighTemp_Alarm").Write 1
Else
    HMIRuntime.Tags("HighTemp_Alarm").Write 0
End If

Simple VBScript that checks a tag value and triggers an alarm if out of range.

C Script Example in WinCC

#include "apdefap.h"

void ToggleOutput()
{
    float level;
    GetTagFloat("Tank_Level", &level);

    if(level > 75.0)
    {
        SetTagBit("Pump_On", 1);
    }
    else
    {
        SetTagBit("Pump_On", 0);
    }
}

Internal C script in WinCC that toggles a digital output based on tag state.
