Sigma South

I cannot see both sides of the data.  I can assume AD1024 on the Profinet side is going to be a large number between 900,000 and 20,000,000.  I can also assume AD1036 and AD1040 will be somewhere between 200.000 and 600.000.  These are safe assumptions, so I would like to try and do everything on the Modbus side to see if I can get close before I ask the OEM for further help. Thank you Bill Mobile Phone:  708-556-2929  

Thanks.  Evening hours work for me.  Call me or text me to schedule.  Do you think it would be this evening or possibly tomorrow?

Ahh.  Thank you so much.  Lol.  So, I tried converting and I am still struggling.  If you are open to working with me for 2 hours via Team Viewer I would be glad to pay you.  I really need to get this project closed and have been struggling for some time now.   708-556-2929

I am also wondering how 1.50967693E+28f is the same thing as 238.02f.  What Am I missing?

Panic Mode, Thank you.  I am so close now.  I notice in the OEM's chart above that the value for the first 3 registers are decimal and they display a value in the OEM's documentation with "L#".  Is "L#" not part of the actual value in your opinion? Thanks

iAdmin, I tried your method like this:             float vIn = 238.02f;             byte[] vTemp1 = BitConverter.GetBytes(vIn);             byte[] vTemp2 = new byte[] { 0, 0, 0, 0 };             vTemp2[0] = vTemp1[1];             vTemp2[1] = vTemp1[0];             vTemp2[2] = vTemp1[3];             vTemp2[3] = vTemp1[2];             float vOut = Convert.ToSingle(BitConverter.ToDouble(vTemp2, 0 /* Which byte position to convert */));             Console.WriteLine(vOut);             Console.ReadKey(); And I get the following error: "Destination array is not long enough to copy all the items in the collection. Check array index and length". Can you help?

Notice the first three are not floats.  They are decimals.  I'm not even sure at what register I should start at in the ModBus holding registers.  Also, what method should I use? http://easymodbustcp.net/en/modbusclient-methods

I am willing to pay someone who is knowledgeable in this are to help me remotely solve this problem.  (TeamViewer) I have a Profinet PLC with data as shown in the image below. I have a converter that translates the data into TCP/Modbus. I have tried reading the data using a few existing client applications as well as a C# library called EasyModbus that I have used on projects before. I am getting data back but I cannot make sense of it. I have only used TCP/Modbus with integers before so it was easy. I am looking for someone with extensive experience to assist.
