vb code for an analogue value of 4-20ma which means 0-100°C and when temperature is more than 50°C an output "alarm" will flash with 1hz
antwort:
Here is an example of how you could write VB code to display an analogue value of 4-20mA, representing a temperature range of 0-100°C, and to flash the word "alarm" at a frequency of 1Hz when the temperature is above 50°C:
Code:
' Declare a variable to store the temperature value
Dim temperature As Single
' Declare a flag to track whether the alarm is flashing
Dim alarmFlashing As Boolean
' Declare a timer to control the flashing of the alarm
Dim alarmTimer As New Timer
' Set the interval of the timer to 500ms (half a second)
alarmTimer.Interval = 500
' Add an event handler for the timer's tick event
AddHandler alarmTimer.Tick, AddressOf AlarmTimer_Tick
' Read the analogue input value from a 4-20mA transmitter
temperature = ReadAnalogueInput()
' Convert the input value to a temperature in degrees Celsius
temperature = (temperature - 4) * (100 / 16)
' If the temperature is above 50°C, start flashing the alarm
If temperature > 50 Then
alarmFlashing = True
alarmTimer.Start()
Else
' Otherwise, stop the timer and hide the alarm label
alarmTimer.Stop()
lblAlarm.Visible = False
End If
' Update the temperature label with the current temperature value
lblTemperature.Text = temperature & "°C"
' Event handler for the alarm timer's tick event
Private Sub AlarmTimer_Tick(sender As Object, e As EventArgs)
' Toggle the visibility of the alarm label
lblAlarm.Visible = Not lblAlarm.Visible
End Sub
This code declares a variable to store the temperature value, and a flag to track whether the alarm is flashing. It also creates a timer with an interval of 500ms (half a second) and adds an event handler for the timer's tick event. The event handler toggles the visibility of the "alarm" label. If the temperature is above 50°C, the code starts the timer and sets the alarmFlashing flag to True, causing the "alarm" label to flash at a frequency of 1Hz. If the temperature is below 50°C, the code stops the timer and hides the "alarm" label.

2. Antwort (gleiche Aufgabe):
Here is an example of how you can create a Visual Basic program that displays an analogue value in the range of 4-20mA, representing a temperature range of 0-100°C, and flashes an "alarm" message when the temperature exceeds 50°C:
Code:
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
' Set the minimum and maximum values for the analogue value
ProgressBar1.Minimum = 4
ProgressBar1.Maximum = 20
' Set the initial temperature to 0°C
Dim temperature As Integer = 0
' Set the timer interval to 1000 milliseconds (1 second)
Timer1.Interval = 1000
' Start the timer
Timer1.Start()
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
' Increment the temperature by 1°C every second
temperature += 1
' Calculate the analogue value based on the temperature
Dim analogueValue As Integer = (temperature * 16) / 100 + 4
' Update the progress bar to display the analogue value
ProgressBar1.Value = analogueValue
' If the temperature exceeds 50°C, flash the alarm message
If temperature > 50 Then
If Label1.Visible Then
Label1.Visible = False
Else
Label1.Visible = True
End If
Else
' If the temperature is below 50°C, make sure the alarm message is not visible
Label1.Visible = False
End If
End Sub
End Class
This code creates a form with a progress bar and a label, and then uses a timer to update the progress bar and display the "alarm" message at a 1Hz frequency when the temperature exceeds 50°C. The progress bar is used to display the analogue value in the range of 4-20mA, and the label is used to display the "alarm" message. The timer is set to trigger an event every second, which updates the temperature, calculates the analogue value based on the temperature, and updates the progress bar and label accordingly.

3. Lösung:
Here is an example of how you can write a Visual Basic (VB) program to read an analogue value in the range of 4-20mA and display the corresponding temperature in degrees Celsius, as well as flashing an "alarm" message if the temperature exceeds 50°C:
Code:
Public Class Form1
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
' Read the analogue value
Dim analogueValue As Double = ReadAnalogueValue()
' Convert the analogue value to a temperature in degrees Celsius
Dim temperature As Double = (analogueValue - 4) * (100 / 16)
' Update the temperature label
lblTemperature.Text = temperature & "°C"
' Flash the alarm message if the temperature is above 50°C
If temperature > 50 Then
lblAlarm.Visible = Not lblAlarm.Visible
Else
lblAlarm.Visible = False
End If
End Sub
End Class
This code assumes that you have a timer control on your form that is set to tick at 1Hz, and that you have a label control on the form to display the temperature and another label control to display the alarm message. The ReadAnalogueValue function in the code is a placeholder for the code that reads the actual analogue value. You will need to replace this with code to read the value from your specific hardware setup.
When the timer ticks, the event handler function is called and reads the analogue value. It then converts the value to a temperature in degrees Celsius using the formula provided, and updates the temperature label with the new value. If the temperature is above 50°C, the event handler function toggles the visibility of the alarm label, causing it to flash on and off at 1Hz. If the temperature is below 50°C, the alarm label is kept hidden.
ich denke man muss etwas genau schreiben was man will. gerade das mit dem blinken hat es nicht 100% verstanden.
zb so:
aufgabe:
vb code for an analogue value of 4-20ma ,
scale it to 0-100°C.
Temperature more than 50°C set a 1hz blinking digital output "alarm".
when temperature below 50°C output is off
Lösung 4:
Here is an example of how you can write a Visual Basic (VB) program to read an analogue value in the range of 4-20mA, scale it to a temperature in the range of 0-100°C, and set a flashing digital output to "alarm" if the temperature exceeds 50°C, while keeping the output off when the temperature is below 50°C:
Code:
Public Class Form1
Private isAlarmOn As Boolean = False
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
' Read the analogue value
Dim analogueValue As Double = ReadAnalogueValue()
' Convert the analogue value to a temperature in degrees Celsius
Dim temperature As Double = (analogueValue - 4) * (100 / 16)
' Update the temperature label
lblTemperature.Text = temperature & "°C"
' Set the digital output to "alarm" if the temperature is above 50°C
If temperature > 50 Then
isAlarmOn = Not isAlarmOn
If isAlarmOn Then
SetDigitalOutput("alarm")
Else
ClearDigitalOutput("alarm")
End If
Else
isAlarmOn = False
ClearDigitalOutput("alarm")
End If
End Sub
End Class
This code assumes that you have a timer control on your form that is set to tick at 1Hz, and that you have a label control on the form to display the temperature. The ReadAnalogueValue function in the code is a placeholder for the code that reads the actual analogue value. You will need to replace this with code to read the value from your specific hardware setup. The SetDigitalOutput and ClearDigitalOutput functions are placeholders for the code that sets and clears the digital output, respectively. You will need to replace these with code to control the digital output on your specific hardware setup.
