Hello!
I have a problem with NI Modbus Library.
When I was testing the modbus Ethernet examples from the NI MB llb I discovered one funny case...
It is working with ordinary Ethernet cable, but does not work properly if I use only 4 wires of the cable (1,2,3 and 6 wires).
I guess it should be enough to use 4 wires.
So, the problem: I use one Slave and several Masters and the ethernet cable category 7. If I use 4 wires of the cable then I can use only one Master.
But when I try to connect another one Master then the Slave buzz and does not answer. I can not understand it...
If somebody knows the problem, answer me, plz
