Difference between revisions of "Modbus TCP/IP to NVGate"

• General

o Label: Name of the input displayed in NVGate.

o User unit: the unit as described in the Units.xlsx

o Min value and Max value: The minimum and maximum value (expressed in user unit). The min value must correspond to Bus data min, and the max value must correspond to Bus data max, i.e., if a temperature in [-20, 100] can be encoded on the bus with values in [-200, 1000]. So, range min = -20 and max = 100.

• Modbus input

o Address: the register address.

o Type: type of MODBUS request (among Discrete Input, Internal Bits, Holding Register, Input Register).

o Bit: for Discrete Input or Internal Bits, the position of the bit in the register

o Bus min, Bus max: Bus data: see range (in this example, the values must be min = -200 and max = 1000).

• NVGate Simulated DC number: Must be in [1, 32].

• Measurement properties (the parameters are metadata written in the measurement when the recording stops. They are accessible from Measurement Properties in NVGate.)

o Name: the name displayed in NVGate.

o Method: how the value is computed (first, last, min, max, average). If the method is ‘file’, the value is read from the Properties file.

o # digits after dot: value rounding.
