Hi Phong,

To answer your question, I used async method for send to enable a send timeout ability. As for receive, I used sync method because I already know the receive method will not block as I check for available data (via poll) before I attempt to read.

Hi Phong, The timeout in the send function is based on the ability of the underlying Socket, not so much what it is being used for so this should not matter. The receive however does. In this case, what I've done in the past is to peek if there is data available before I use the ReceiveAll function....

Hi Phong, The answer to this question was actually buried in the Modbus Client class I sent you ( http://ixtalk.beijerelectronics.com/viewtopic.php?f=5&t=2289&sid=bad94095cd38d095f0f2a072c489fe97 ). When a TCP connection is half-dropped the underlying Socket.Connected property still returns true as ...

Hi ajack, I've pulled the core part of this out of one of my script modules (Comms). This uses the Created event to start the thread and timer. Sadly, iX does not have a Destroyed event so what I've done is use the class destructor to clean up the threading. //---------------------------------------...

Hi ajack, 1. Given the option, I typically use Asynchronous socket connections (as was in my sample script). 2. How acquainted are you with multi threading? What I typically use to drive a cyclic process is a System.Threading.Timer. Script modules have a "Created" event that fires during startup whe...

I don't work for Beijer so you'd have to contact customer support to get exact answer, but as far as I know there is no raw communication driver. What I could send you as a scripting module would only be a direct copy of what I attached in my prior response. The code was more for example of how you ...

Hi ajack, You can do that by creating a custom script module and using a Socket. For example, below I have included the source code for a ModbusTCP client I created to read holding registers. you will need to add the following using's to the head of your script module: using System.Net; using System...

Hi ajack,

TCP IP just indicates the connection is over Ethernet. What is the underlying communication protocol? Based on your mention of hyperterminal I'm assuming it's ascii-based like telnet.

Mishra, What customization are you trying to do with this dialog? In my last response I indicated how to create custom dialogs in general. You can access user information through the Globals.Security object. For example, the following code checks if logged in user is in a specific group: public bool...

There is a way to set an object's text to a text ID via script. To do this you need 3 things: the ID of the text you want, its default value, and the following code. public string GetTextID(uint textId, string defaultValue) { Neo.ApplicationFramework.Tools.MultiLanguage.MultiLanguageResourceManager ...
