    Can't ping Bentley Nevada although the values are visible!

    So we have changed the old network switches from which I could ping Bentley Nevada and RX3i but with the new ones I cant ping them alyhough I can see their values on the HMI.How can I resolve the problem?

    Can two gas turbines working in droop mode be connected to the same grid?

    So my quesstion is simple.Let's suppose to have two gas turbines working in droop mode.At this moment they are operating at the same frequency(same rpm) and they are connected to the same grid.What if I decide to give a command to one of the gas turbines to change it's active load and...

    Is there any difference between P and Y I/O packs in the MarkVIe Control System?

    Basically the title,it seems like every I/O pack that is connected to the MarkVies Control System is the same as the one connected to the MarkVIe Control System except the reliability of the I/O pack.So what is unclear to me is there any difference on what they do?of course if I have connected...

    Do all I/O Net Ethernet cable transmit information?

    So,let's suppose we have a Mark VIe in a TMR Configuration,when the Mark Vie is sending information to the I/O packs,because it wants to deliver an output,is the information through all 3 I/O Net Ethernet(R,S,T) cables? And another question,when the controllers are sending an output and that...

    How do we change the power of an electric generator without changing the frequency?

    Let's suppose we have a gas turbine which is connected to an electric generator.Now it says that we can increase the power of the electric generator,but to increase that power we would need to increase the rotation of the gas turbine,but increasing the rotation we would change the frequence of...

    How do devices archieve floating voltage?

    What I mean by this is that how can the difference between two points can remain at the same voltage,for example always having a difference of 24v between two points,even although one of them is touching the ground.So let there be two points A and B. One of them (A) has a voltage difference of...
