euro808

[etay23]

Hi,

I want to control on Eurotherm 2216e with LV 8.2

I was told by their representive to install this driver 'euro808 '

When i use the VI's supplied I need to enter Group ID and Number ID... otherwise it doesn't work

what shoul i do?

My first problem was to read teprature. i used the PV command like that: \040011PV\0

and the respone was: \02PV22.0\03 if the Temp was 22 C. the problem was to read that temprature because somtime, after the 03\ there was more charecters.

so i install the 808 driver in order to be able to send only PV and get only the Temp.

am i being clear?

Thanks alot for your time,

etay

Hi etay,

I would like to first point out that the specific driver you mention is not NI Certified and therefore is not guaranteed to work, especially since you are using a different model than it is written for. Having said that, you could use a case statement to see if the input is PV and if so then write \040011PV\0 to the device. You could then parse the response to look for the 4 temperature digits (in this example 22.0) that come after \02PV. Regarding the Group ID and Number ID - Is it a problem to need to enter them? If entering those is the only way to get the VIs to work then there isn't really a way to get around it without modifying the driver VIs themselves. I hope this helps!

What you said was much of a help! now I'm dealing with another problem:

after sending the command in the way you said, i can read the Temprature exacly as you said: 02PV(4 digit Temp.)\03,

But, from some resone, when I'm send comman for Set Temprature (SL) the device respone is \06 and if i send read temprature command then before the 02 i have now \06\02 (only for the first time, if i try to read agin the 06 disappears).

In my program i set temprature and then i read the Temp this 06 is problem.

regards,

Hi etay,

why is it a problem?
Just skip the /06/02 by searching for 'PV' in your string and convert the number after 'PV' to temperature value...

Btw. I use just '00' for both Group and Unit, works perfectly with older EuroTherm818
