🔹 Node Info

Read your node's information

  • Node Name displays the name of your node. (A node can be a Drive/Inverter or an IO Block)
  • Vendor displays the vendor ID specified in the manufacturer's ESI file.
  • Product displays the product ID specified in the manufacturer's ESI file.
  • Revision displays the revision number specified in the manufacturer's ESI file.
  • Station Alias The EtherCAT station alias.
  • Serial # represents your nodes' uniquely identifiable ID. Every node will have a different Serial #.
  • Digital In displays the number of Digital Inputs your node contains.
  • Digital Out displays the number of Digital Outputs your node contains.
  • Analog In displays the number of Analog Inputs your node contains.
  • Analog Out displays the number of Digital Outputs your node contains.
  • Segments The number of segments on this node.

🔹 SDO Read

  • Index is used to address an entry within the object dictionary. Indexes can represent a single object (variable) or multiple objects (an array or record).
  • Sub-Index is used to access individual elements of an object dictionary entry/index.
    • For single object dictionary entries such as an Unsigned8, Boolean, Integer32, etc. the value for the sub-index is always zero.
    • For complex object dictionary entries such as arrays or records with multiple data fields the sub-index refers to fields within a data-structure pointed to by the main index. Index counting starts with one.
  • Read Type allows to specify how you want to insert your Byte Count. As an Integer or as a String.
  • Byte Count is used to specify the size of the object dictionary entry/index.
  • Continuous Toggle-Button allows you to read the specified index periodically. (No need to press Read button)
  • Read Button allows you to read the specified Index.
  • Signed CheckBox allows you to display the result as a signed value instead of an unsigned value.
  • Result Field displays the read specified Index value.
  • Dec-Hex-Bin-Str ListBox allows you to change the way your result value is displayed.

  • Write Button allows you to write the specified Value to the specified Index.
