I am using a Siemens PAC 3200 device that reads information from the mains such as voltage, current, etc. The manual for this device tells you the registers sent by MODBUS, some of them Float type and some Double type. Float-type ones I can read quietly. But the Double type I can not. Following are some images to better exemplify
I want get real value ?
sameone have an idea how to convert to float ??
The buffer-parser node can turn that buffer into pretty much any format your need.
Here are some of the demo examples built-in (you access built in demos from node-red hamburger menu, import, examples)...
thanks for your reply ,
