Hello,
I start with my device "VACCU SELECT" to communicate with LabVIEW. To do this I use RS 232 Serial port with VISA.In the catalog I have all the necessary instructions to control and acquire continuously the pressure data.The connection is well made and the instrument responds very well, until the moment I have some questions to use these instructions.
1- do I have to send the commands instruction by instruction? and if I send a list of instructions in concatenated chain, does it work or not? I tried it, it responds and sends back all the answers but it is long.
the device answers a little long sometimes, and it is marked on the manual that it is necessary to put a wait of 100 ms between two successive instructions.
so my question is :
2- how can I send two successive instructions to the VISA with a wait of 100 ms.
Is the response of the device of the order of a few seconds (4s) tolerable, because it occupies of the regulation which is its principal mission. the problem here with what the moment or it makes the regulation it sends more answer as long as it is not finished the process?
I've been stuck for a week in my project as I work alone, I've searched everywhere but I haven't found answers to my questions nor detailed pdf courses for the control instrument part with visa and SCPI commands.
Someone could clarify things for me, I will put the user manual
