ICPCON i-7540D command list to communicate over RS485

TejaskumarPatel · ‎07-18-2013

Hello All,

I am trying to communicate icpcon i-7043D (RS485, DO- digital output 16 ch) via icpcon (i-7540D Ethernet).

I can communicate with other COMports availabe (Using VxCOMM) e.g. COM1(RS232) COM3 (CAN). BUt I can´t connect COM2 (RS485).

Do anyone know how can I send command to this IcpCon 7-7043D ?

Regard´s,

Tejas

Hi Tejas,

first, I have to say i haven't heard of this manufacturer before, so all i can do is to give you some general advice.

I found these LV-drivers on their Homepage, normaly it should get the job done:

I havent tried them (since I don't own the hardware), but normaly you can just drag and drop them on your block diagramm, and it should work.

If you still experience issues with that, post some screenshots!

Thank you Oliver,

For oyur time and reply.

When I use this driver I get response from hardware. But there are some more commands (http://www.icpdas.com/products/Remote_IO/i-7000/i-7043d.htm), which I cant use with this driver.

From my understanding its only possible via TCP Open & Write funtion but it didnt work.

Hi Tejas,

can you give me an example of a command that you cant use? All I could find behind the link was a list of specifications of the device.

If a command is not included in the driver, you can call a dll with the call library function:

If you understand german, or want to use a translator, you can find an in-depth-tutorial here:

the dll can be found on the same download page:

If that doesn't answer you question, please explain how you used the open&write func, and how it did fail.
