I have the same problem as you, too. I'm trying to control a VTS 7060-5 via RS232 and the ASCII-2 protocol. It's even no problem to set nominal values of the temperature or the humidity, but I'm even not able to control the digital ports (especially I want to controll the "Start" signal too).
I have read a lot of posts so far and still got no clue what's wrong.
I tried to change the control mode on the touch panel, but in every mode I was able to change nominal values via LabVIEW, but still not the digital ports.
Does anybody here found a cause or a way to handle it just with the ASCII-2?
And thank you for all the informations so far!
The "Start" signal indicates if a cycle is running and can't be set directly with a specific command.
with xx = address of the chamber and yyyy = number of the cycle
According to the protocol, there is no command to set the digital outputs. You have to configure them when editing the cycle (with S!MPATI).
I suggest you to contact Vötsch for further details.
In the manual mode via Touchpanel I can set the digital channel "Start". Then the clima chamber starts heating or cooling according to the nominal value.
The string to set nomial values refering to the ASCII-2 protocol looks like this:
So why should/can I send the state of the digital channels in the Edit-String, when I can't change them there?
That makes no sense for me.
I already contacted Vötsch with that question.
Thanks for your reply.
I don't know why, but now my system works.
I contacted Vötsch and the Service gave me the clue to look up what my system is able to do by sending the string $xx?<CR>.
The systems output were examples for E- and I-Strings. I used the example of the E-String and it worked.
Afterwards I sent the string I was using before and it works too.
So I don't know what was wrong, but I works.
May I please ask you to share your library with me?
I am trying to control VCL 4010, VT37006 and VTV 4060 using ASCII-2 protocol.
But apprently the device does not want to respond to me.
I have the same problem, too.
My climatic chamber VT4021 didn't work with this string.
$01E 0050.0 0000.0 0000.0 0000.0 0000.0 0000.0 01000000000000000000000000000000 <CR>
After I set the Value for setting Fan speed to 100%, it will be work.
