Hello  
I am not able to find an example of c# application to understand:

- how to connect to a simulator instance (127.0.0.1)
- how to read a variable  
with PVI 4.11

Is there someone that has an example or a snippet?  
Thank you very much in advance

Marco Sartori

Hi, all official sample you can find in PVI installation folder. Default path is C:\BrAutomation\PVI\V4.11\Samples

Yes, but there is no example where ArSim is used…

Question is: which properties should be set on connection?

Hi,

adapting the code to your needs requires looking at the generated documentation.

Going from the [CPU object](https://help.br-automation.com/#/en/6/automationnet%2Fpviservices%2Fclassreference%2Ft_br_an_pviservices_cpu.htm) to the type of its’ [Connection object](https://help.br-automation.com/#/en/6/automationnet/pviservices/classreference/t_br_an_pviservices_connection.htm) and looking at [DeviceType](https://help.br-automation.com/#/en/6/automationnet/pviservices/classreference/t_br_an_pviservices_devicetype.htm):

The example would get you something like this (I didn’t bother to change the style to that older line-by-line one):

```auto
cpu = new Cpu(service, "Cpu") {
	Connection = {
		DeviceType = DeviceType.ANSLTcp,
		ANSLTcp = {
			DestinationIpAddress = "127.0.0.1"
		},
		ResponseTimeout = 5
	}
};

```

Ahahah.  
Many thanks @michael_w  
Sorry for the late reply. I had the chance only to test the connection and it worked perfectly.  
Hope this help someone else that has basic knowledges on c# like me 😂

Thanks again
