Hi, I have installed http://flows.nodered.org/node/node-red-contrib-modbus and I cannot find an area to change the value type for modbus. Seems like the node is a somewhat complete, but is missing few things. Primarily the value type. There are signed and unsigned integers as well as floats. The Modbus node is able to talk to unsigned integers just fine, but I have a current sensing energy monitoring CT's that use floats as their registers. I assume I need to use a function inorder to achieve what I need to do, but I just today i found out about node-red and learning the ropes. Can someome assist in the function or what needs to happen to get the value I am looking for.

Here's the CT documentation
https://www.ccontrols.com/support/dp/EnerceptMeterInstallationGuide.pdf starts on page 17 for the addresses.
THank you.
