It's currently in the store in the development channel.

That makes considerably more sense. So, they could be four contiguous registers and just storing the values of different magnitudes.

Thanks for answering his question mdh, and welcome to the forum!

Basically, you'd multiply the normal register reads by various powers of 10000 in order to create a 5 digit offset, and then add them all together to get the larger value.

I am fairly certain you will not be able to do this with the current version of Modbus4J, but I confess I am not too familiar with mod10k (it's not in my protocol spec reference! some googling indicates it's a proprietary extension?). Some playing with our Modbus data source suggests you cannot exceed register offset 65535 in making requests, so you will not be able to request the registers at 10000^2 and 10000^3

Read all 4 registers physically with the Modbus driver (if your particular example involves 4 registers), and then put them together with the Mod10K math in a scripted point.

They typically use 4 registers (let's call them A, B, C and D) and then they stitch them together with a formula that goes a bit like this:

(A) + (B)(10000) + (C)(10000^2) + (D)*(10000^3) = Total Value

It is a pretty common way of packing large values in Modbus land.

(edit - kicked the powers of 10 on those 10K values, should be good now)
