Article Summary

After configuring the channel, device, transaction, and steps, the tags associated to the different transactions will also need to be created.

Figure 13. Tag settings


  • Device: This is used to associate this tag with a device. The format of this parameter is Channel/Device. In this example, the Channel is labelled "Example", and the Device is labelled "Device01".
  • Read: This section is used to obtain a value from a transaction and save it to this tag:
    • Enabled: Enables or disables reads. When disabled, the bound variable won’t be defined (and any attempt to update it will result in an error).
    • Transaction: Used to select the transaction that the tag value will be updated with.
    • Variable: This variable is used to update the tag value. This can be done either using a Regular Expression step, or by using $.variableSet  in a script step.
  • Write: This section is used to initiate a write transaction whenever a tag is written by the user or by a different module.
    • Enabled: Enables or disables writes. When disabled, writes for this tag will be omitted.
    • Transaction: Used to select the transaction that will be launched when this tag is written.
    • Variable: The variable to be updated when this tag is written. The value of this variable can be obtained in script steps by using $.variableGet.
