Script error snap7.dll

[Doebe]

Hello

i want to send data from homeseer to a siemens PLC but get some errors when trying to create a script.

I am trying to call a DLL but i get some error messages :

Error

Compiling script C:\Program Files (x86)\HomeSeer HS3\scripts\TX_PLC.vb: Type 'Snap7.S7Client' is not defined.

Error

Compiling script C:\Program Files (x86)\HomeSeer HS3\scripts\TX_PLC.vb: Namespace or type specified in the Imports 'Snap7' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

Error

Compiling script C:\Program Files (x86)\HomeSeer HS3\scripts\TX_PLC.vb: Namespace or type specified in the Imports 'System.Core' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

The DLL is referenced in the settings.ini :

ScriptingReferences=DDay.iCal;DDay.iCal.dll,DDay.Collections ;DDay.Collections.dll,antlr.runtime;antlr.runtime.dll;snap7. net;Snap7.net.dll

also the filles are copied in : C:\Program Files (x86)\HomeSeer HS3\

But i got 2 filles : Snap7.dll and Snap7.net.dll

i tried both of them, also i checked if i used the correct file x86 vs x64,

according to http://snap7.sourceforge.net/
VB

Unluckily for you, you cannot use directly snap7.net.cs in your program because it’s a c# source class library.
To be used, the wrapper must be compiled into a compiled class library, i.e. an “universal” .net library that can be loaded by any .net language.
You need of : snap7.net.dll
In spite of its extension, snap7.net.dll is not a windows DLL (like snap7.dll) but a class library. Thank Microsoft for the enlightening name
So, in order to use the snap7 classes, you need to import snap7.net.dll referencing it into the project properties, otherwise the compiler does not know how to find them.

so should i reference snap7.dll or snap7.net.dll ?


some code i use :

Imports Snap7

Sub Main(ByVal Parms As Object)
'==========================================================
'Modify these to fit your system
dim PLC_IP = "192.168.0.199"
Dim UDTLength = 100
'==========================================================
Dim Buffer() As Byte ' Buffer
Dim Client As Snap7.S7Client ' Client Object

Thx. Doebe

My guess is the object definition is incorrect. I'd recommend that you check the tenScripting application. It's very instructive and a powerful way to tackle scripting in HomeSeer.

Thank you i will have a look

ScriptingReferences=DDay.iCal;DDay.iCal.dll,DDay.Collections ;DDay.Collections.dll,antlr.runtime;antlr.runtime.dll;snap7. net;Snap7.net.dll

Should there be a space here? snap7. net

I've typically provided the full path for libraries like that:

ScriptingReferences=System.Data.SQLite;C:\Program Files (x86)\HomeSeer HS3\Bin\System.Data.SQLite.dll,System.Management;System.Management.dll,System.Web;System.web.dll,System.Windows.Forms;System.Windows.Forms.dll,System.Drawing;System.Drawing.dll,Newtonsoft.Json;C:\Program Files (x86)\HomeSeer HS3\Bin\homeseer\Newtonsoft.Json.dll,System.Web.Extensions;System.Web.Extensions.dll

May be worth trying. I would move the dll files into a sub-directory under the Bin folder, rather than in the HS root folder.

Should there be a space here? snap7. net

Probably a forum issue as it sometimes inserts spaces like that when you paste text into a post.

Space is indeed coming from copy/paste.
i also tried full path, nog changes here.

if i have time i will try tenscripting option to see if there is some problem.
