Need the following Read holding register 1620 - 1623 Preform math integer math function as follows from values in these registers (Value of 162310000^3)+(Value of 162210000^2)+(Value of 1621*10000)+(Value of 1620) Concerned if we do an individual read the math will not work as one output value …

Why have you started a new thread? What's different to this one... [image] Very Large Numbers Modulo 10k General Here is how modulo 10k is described. 64-bit unsigned value returned in four consecutive 16-bit registers, where R4 is the last register and R1 is the first r…

Node Red Forum would not let me attach or send lager captures. Decided to make clear what I was trying to do. With a typical modbus block read I should be able to separate the output rather than getting a string such as 571,6584,16.0 Each one of these is a value that we need to conduct Modulo 10k…

You should read four registers in one go and pass it to the buffer parser node to convert.

Solution already posted in OPs other thread

Have been using Modbus reads for decades. While reading four registers the out put of the block (node) would typically produce four output links. the modbustcp node I am using allows to configure for a block read but does not produce individual output links for the data being read. The debug show…

Steve-Mcl. Many thanks for your help. Unfortunately while attempting to load BigInt from the Pallet Library Node-Red produced a "Fail to install:" message with an "Install failed" and "Check the log for more information" statement. Not BigInt does not show up in the Palette Install tab with a key…
