There are essentially 2 ways to read Analog inputs: reading current or reading voltage. Current is generally the most common because it can reach longer distances across the wire without losing analog input signal. Voltage, on the other-hand, will degrade over long distances producing inaccurate readings. When working with devices that only read 1-5V [...]

Most SCADA Integrators and users of modbus are familiar with the X0001 format for modbus registers, However, the true modbus standard is not simply one number it is a function code + register number. Specific devices treat the function codes differently on the front-end. The back end will interpret the 40000 registers [...]
