Hello everyone.
I'm currently trying to establish a communication between a Superflow SF1020 bench and Labview thought a Modbus protocol and I'm meeting a few troubles...
First of all, the device can be seen by MAX properly only when i just rebooted the computer. At this moment, I can open the VISA panel and see on his attributes that "Is Port Connected" has an "Invalid Property Value" on his current value.
At this point, I tried some examples found on modbus library or on topics given by labview community and It always starts the same way : I just have to choose "Com 1" for the visa ressource name before the system detect the instrument and so I can finally choose "ASRL1::INSTR". At this moment, MAX can only see that the interface name is "unknown". As the device is "reserved" by the program, I can understand that it is not usable anymore, but as I'm not an expert, I prefer to explain all the details, in case it could help.
Among all the examples I found, most of them end the same way, with the famous visa read error -1073807298 that I've never succeed in overpassing it, even with the help of many older topics :

and I just quoted the official solutions ...
Besides, I also tried to do a Modbus I/O server to see if there was any piece of informations that was transfered by the bench and there was none. As a result, the attribute "CommFail" was on true state...
As I'm not used to Modbus protocol or serial instruments, I'm not even sure if the communication was well set or if my problems come from the SF1020 or my lack of modbus communication knowledges. In that way, if any of you know how to solve my problems or at least one of them, help will be warmly welcomed
