Can ClearScada.Client.dll be used from PowerShell Core?

[_Experimentalist_]

Hi

I have a script that allows me to query the Geo SCADA Expert database from Windows Powershell 5.1 and it works fine. When I use the same script with in PowerShell Core 7.4.1 the ClearScada.Client.ServerNode Connect method throws a ClearScada.Client.CommunicationsException when the request timeout expires. I have shortened this request timeout to 15 seconds in the code sample to help speed up the investigation. The exception thrown is not giving me much to go on but I have a sneaking suspicion it is to do with NLog in Geo SCADA Expert.

Here is a short script that will replicate the error:

Import-Module 'C:\Program Files (x86)\Schneider Electric\ClearSCADA\ClearScada.Client.dll'

Clear-Host

$hostName = "127.0.0.1"
$system = "Local"
$clientName = "PS-Client"
# Get username from user, enter accepts default offered which is the logged on user name
if (($username = Read-Host -Prompt "Username [$env:USERNAME]") -eq "") {$username= "$env:USERNAME"} 
$password = Read-Host -AsSecureString -Prompt $("Enter Password for {0}" -f $system)

try
{
    try
    {
        $node = [ClearScada.Client.ServerNode]::new([ClearScada.Client.ConnectionType]::Standard, $hostName, 5481)
        $node.RequestTimeout=150000000 # 15 Seconds
        # Version 6.84
        $serverInterface = $node.Connect($clientName, $false) #  Returns [ClearScada.Client.Advanced.IServer]

        if($password.Length -Eq 0)
        {
            "No password was entered"
        }
        else
        {
            try
            {
                "Logging on . . ."
                $serverInterface.LogOn($username, $password)
                
                if($serverInterface.IsLoggedOn)
                {
                    "Logged in successfully, logging off . . ."
                    $serverInterface.LogOff()
                    "Logged off, disposing . . ."
                    $serverInterface.Dispose()
                    "Disposed, finished"
                }
                else
                {
                    "Login failed"
                }
            }
            catch
            {
                throw
            }
        }	
    }
    catch
    {
        "`r`n{0}:" -f $_.FullyQualifiedErrorId
        $_.Exception | Where-Object {$_.MemberType -ne 'Method'} | Format-List
    }
}
catch
{
    Write-Host "An unhandled exception occurred:"
    $msg = "`t{0}" -f $_.Exception.Message
    Write-Host $msg
    Write-Host ''
}

PowerShell ISE and Windows PowerShell are a dying breed and PowerShell Core is where it's all going so I would love to resolve this.

Anyone have any idea how to fix it?

Looks like PowerShell Core 7.4 is using .NET 8, the ClearSCADA.Client.DLL needs .NET 4.8. Some more discussion at https://community.se.com/t5/EcoStruxure-Geo-SCADA-Expert/FYI-Applications-built-on-Net-Core-worked-w... I've not heard of any recent changes to the supported .NET versions

Hi Adam, thanks for that, not what i really wanted to hear but thanks all the same. That link didn't work but hopefully this one will:

FYI Applications built on Net Core worked with Geo SCADA 2019

If I use the ClearScada.Client.dll from Geo SCADA Expert 6.86.8863.1 in my Import-Module statement I can successfully logon and query from my  6.84.8218.1 database.

Ooh, that's good to know, maybe they have updated the supported frameworks in Geo SCADA 2023

This bug (CSUP-13435) has been fixed in the March 2024 releases of GSE 2022 (6.85.8853) and GSE 2023 (6.86.8863) onward, but was mistakenly missed from the release notes. The fix was tested with .NET Framework 4.8 and .NET 7.

Officially only .NET Framework 4.8 is supported by Geo SCADA 2023 (and earlier versions).
