Object 60 Variation 3

Object 60 Variation 4

W/O.

Writing a ‘1’ to this tag will instruct the unit not to broadcast any more unsolicited responses. It is W/O, as there is no way of determining if unsoliciteds were disabled before Plant SCADA startup.

Enable all Unsoliciteds

Object 60 Variation 2

Object 60 Variation 3

Object 60 Variation 4

W/O.

Writing a ‘1’ to this tag will allow the unit to broadcast unsolicited responses.

It is W/O, as there is no way of determining if unsoliciteds were enabled before Plant SCADA startup.

This address does not relate to I/O data internal to the device, but relates to data internal to the driver, or an action to be performed by the driver.

Note: This a Level 3 feature.
