• You are in the Modbus Connector user interface.
  1. Go to Configuration.
  1. Select the device.
  • The Device pane and Data points pane display.
  1. Select Add to add a data point.
  • In the Data points pane, a row for each data point displays.
  1. Complete the fields as follows:
  • Enter a Name for the data point.
  • Enter a Description for the data point.
  • Select the Register type. This setting has following type options: Coil (00001-065536), Discrete Input (10001-165536), Input Register (30001-365536), Holding Register (40001-465536).
  • Select the Address offset. This setting defines the starting address for the type of Modbus register. Ranging from 0 to 65535.
  • Select the Data size and Data type. This setting defines the size (1/16/32/64 bit) and the type (RAW, INT, FLOAT, BOOL) of the register.
  • Enter the Unit for the data point.
  • Select Signed / Unsigned for the register. Signed values represent positive and negative integers ranging from -32768 to 32767. Unsigned values represent only non-negative integers with range from 0 to 65535.
  • Select the Endianness. This setting defines the byte order of the data (big-endian, little-endian).
  • Select the Word order. This setting defines the word order of transmitting the bytes for 16-bit or 32-bit registers. Example: A 16-bit value 0xABCD is in low order first, then it is registered as CD followed by AB.
  • Enter the Slope. This setting provides the option to multiply the data value conversion.
  • Enter the Intercept. This setting provides the option to add an offset, that can be added to the data value.
  • Enter the Precision. This setting provides the option to change the display accuracy of the data value.
  1. Select Save to confirm.
