Combining two 16bit modbus registers into one field

Hi,

I have two 16 bit modbus registers which together will form a 32 bit value that I need to read/record in the eWon Flexy. (Highlighted in the attached image). Is there a way to combine these within a single field within the Flexy somehow?

Thanks.

  I think I have something that might be useful for you but it will end up being in Hex. Let me know if this example helps at all

  Thanks for the file. I could really do with getting the number through in decimal if possible. Is there any way to convert back?

  I am pretty new to setting up this device, how would I implement that sort of script?

  I think if you set it up this way you should be able to do what you're trying to do

  That looks promising. [E] would be the option that I need. How do I actually combine to two addresses into one tag? Do I need to combine the addresses somehow? How do I select what R1 and R2 will be?

  It should be the first address selected and the one address following it

  This is what happens when I try to enter it. Sorry if I'm not understanding this correctly but I can't seem to get it to work.

  Can we try and take a look at this over teamviewer?

  I have tested the implementation of the combined 32bit register and looks to be working fine now.

  For reference if anyone else sees this post. We needed to add the D modifier to read the 32 bits. You enter the address of the first 16 bits and it will grab the following address for the remaining 16 bits.

  Sorry, can i have example coding for this one? (Combining two 16bit unsign int to 32bit unsign int)
