How I can show my feeder off time in hole day. I can use CB trip Tag ‘T1’ and CB close Tag 'T2" . Can any one help me ?

Split from WinCC and Sicam SCC don't send requests to PLC.

Hello indronilroy,
I don't understand what do you want to do, therefore I asked CoPilot ang get following. Maybe it is somthing for you:
To show the feeder off time for the whole day in WinCC, using the CB trip tag T1 and CB close tag T2, you can calculate the total duration when the feeder was off by tracking the time difference between these two events throughout the day.

Here's a general approach:1. Understand the Tags

• T1 (CB Trip): This tag becomes TRUE when the circuit breaker trips (feeder goes OFF).
• T2 (CB Close): This tag becomes TRUE when the circuit breaker closes (feeder goes ON).

2. Create a Script or Logic to Track Off Time

You need to:

• Detect when T1 becomes TRUE (start of OFF period).
• Detect when T2 becomes TRUE (end of OFF period).
• Calculate the time difference between these two events.
• Accumulate this time over the day.

3. Implementation Options

Depending on your WinCC version (e.g., WinCC Professional, WinCC Unified), you can use:

• C scripts or VB scripts in WinCC Runtime.
• Structured Text (ST) in WinCC Unified.
• Tag Logging and Scripts to calculate and store durations.

4. Example Logic (Pseudocode)

' Variables
Dim feederOffStartTime As Date
Dim feederOffDuration As TimeSpan
Dim totalOffTimeToday As TimeSpan


' On T1 (Trip) rising edge
If T1 = TRUE And previousT1 = FALSE Then
    feederOffStartTime = Now
End If


' On T2 (Close) rising edge
If T2 = TRUE And previousT2 = FALSE Then
    feederOffDuration = Now - feederOffStartTime
    totalOffTimeToday = totalOffTimeToday + feederOffDuration
End If

You can display totalOffTimeToday in an HMI tag or log it for reporting.
