unexpected problem happening when connecting said panel to a CJ2M-CPU35 via Ethernet (was replacement of broken NT21 via NT Link). The machine software, running on a thin pc, hangs for minutes frequently, then starts suddenly to work. I have already installed several NB5 with same configuration but this is the first time it gives me problem. I suspect the problem is due to hubs where all pc and plc connects, there are two installed and one is gigabit speed while the other is 100Mbit speed maximum. Other suggestions as to where to look?
