Configuring Variable Tags

The IEC870IP driver supports the following variable tag types:

• Input Tags - tags that allow process information to be passed to Plant SCADA in a monitoring direction

• Read Tags - tag that send a read command to request data

• Output Tags - tag that allow process information to be sent in a control direction

• Control Tags -tags that can be used to send commands in a control direction

• Array Tags - tags that represent array elements

• Virtual Tags - tags that retrieve the status of specific commands.

  Note: The driver supports unstructured tag addresses (e.g. "<IOA>"), as well as structured tag addresses (e.g. "<IOA1>.<IOA2>.<IOA3>"). For more information, see Structured Tag Addressing.
