Vötsch VCL 7010 - ASCII-2 interface protocol

[Nicku]

Hi,

Do you still have that library?

Can you send it to me please?

I have similar problems in controlling the temp chamber using ASCII-2 protocol.

Thanks,

Nicolae

Hi Nicolae,

Hi Christoph,

Thank you very much!

I found also this solution from another post:

Hi!

I am currently working on Vötsch VT4010-ASCII-Interface protocol. It will be of great use if you attach me the library file you have mentioned.

Thanks and Regards

Hello,

I have a Votsch VT7004 climate chamber, I am trying to control it through RS232 with a C# program I've made. I've managed to set the nominal temperature values using ASCII-2 protocol but I am not able to start the oven. If you have any suggestions it would be very useful.

Thank you!

Hi!

Try to send a query to the chamber to know about the nominal parameters of your chamber ($xx?). And also check if your chamber reads all the strings written. post a screenshot if it is possible.

Hi Vlad,

You should take care about the number of groups used to send the command.

This number is different from one chamber to another. If you will use the right number and will put the digital bits after then it should work.

Hello, thank you for the reply, I'm running out of ideas with this chamber.

I have tried a lot of commands but none of them seemed to work, except for the interrogation($xxI<CR>), not really sure the string I have to send to start the oven and heat up to the requested temperature. I have consulted the chamber's manual but the command given there isn't working. I'm not sure if I need to configure the touch screen in order to be able to command it from the PC. Is it possible that ASCII-2 can be used for interrogation and starting the oven or I have to use ASCII-1? And if so, I'm not sure about the ASCII-1 command I have to send.

Below I've attached a screenshot

Hello Vlad,

I saw your program screenshot. I dont have much idea on writing the commands in C. I controlled the chamber with Labview. Basically, the concept should be same. So I will tell you some stuffs which I observed from your code.

There are some strings missing. CV02-Humidity and MV01, MV02, MV03, MV04 (which should be entered even if you dont connect any external sensors) and please correct with the digital pins. It should have 32 pins in total.

P.S: For E-strings, it always differs from chamber to chamber. So that why I asked you to send a query to the chamber to know about the nominal values to be written. And it is possible with ASCII-2 protocol to start the chamber and heat up to the requested temperature. But you should be careful with sending strings.

Regards,

Kalpana

Please check this description. Sorry but it takes too long for details.

The idea is to find the right number of required groups in your command, then to use the same number in all your sent commands, of course where is necessary the real parameters should be set in each group.
