Use the fields at the top of the <Point Type> tab on the appropriate IEC 60870-5 Point Form to configure the general properties of a point. The properties described below are common to many points on IEC 60870-5 outstations:
- In Service—Use to specify whether a point is active or inactive (see Placing an Item In Service in the Geo SCADA Expert Guide to Core Configuration).
- Confirm Disable/Enable—Users with the required permissions can disable a point that is In Service, or enable a point that is not In Service. Such actions are carried out using the Disable Point and Enable Point pick actions.
Use the Confirm Disable/Enable combo box to specify whether a confirmation dialog box is displayed whenever an operator requests that this point is disabled or enabled, (see Requesting Confirmation of Action Requests in the Geo SCADA Expert Guide to Core Configuration).
- Outstation—Specify the outstation on which the point is located. Use the browse button to display a Reference browse window, and choose the required outstation entry.
- Information Object Address—This address, combined with the outstation’s Link Address (where applicable) and Common Address, uniquely identifies a point on a set.
Use the Information Object Address field to specify the address that identifies this point in the outstation. Each point requires a unique address (on that outstation), irrespective of point type.
For outstations that communicate using the IEC 60870-5-101 protocol, the valid range for this address varies, depending on the size that is specified for this address on the Outstation Form (see Specify the IEC 60870-5-101 Parameters).
- If the Information Address Size is 1 Octet, the valid Information Object Address range is 1 to 255 inclusive.
- If the Information Address Size is 2 Octets, the valid Information Object Address range is 1 to 65535 inclusive.
- If the Information Address Size is 3 Octets, the valid Information Object Address range is 1 to 16777215 inclusive.
An outstation that communicates using the IEC 60870-5-104 protocol has an Information Address Size of 3 Octets and therefore has a valid address range of 1 to 16777215 inclusive.
- Severity—Use this combo box to define the severity of any non-state events or alarms for the point.
For more information on severities, see Defining Severities in the Geo SCADA Expert Guide to Core Configuration.
