Geo SCADA Expert can communicate with an IEC 60870-5 Controlling Station (SCADA master station) using either of two IEC 60870-5 protocols (see Supported IEC 60870-5 Communication Protocols).
For either communications protocol, you need to configure one or more IEC 60870-5 Slave Direct Channel(s) in the Geo SCADA Expert database.
You configure the properties of each channel using the fields on the IEC 60870-5 Slave Direct Channel Form.
The Form has several tabs.
Use the fields on the IEC 60870-5 tab to:
then either Configure IEC 60870-5-101 Protocol Properties, or Configure IEC 60870-5-104 Protocol Properties, depending on the chosen protocol.
Use the fields on the Scan Parameters tab to:
- Configure the Scan Parameters—see Defining Scan Parameter Settings for a Channel in the Geo SCADA Expert Guide to Advanced Drivers
- Specify when Communication Statistics are Updated—see Defining the Communication Statistics Update Rate in the Geo SCADA Expert Guide to Advanced Drivers
- Specify any Pre- or Post-Amble Settings—see Defining any Default Pre- and Post-Amble Message Settings for a Channel in the Geo SCADA Expert Guide to Advanced Drivers
ATTENTION: The IEC 60870-5-101 protocol uses 68 to indicate the start of a message. As such, we advise only using 68 as a Pre-Amble where such a character is required by the transmission system, and not to use 68 for Pre- or Post-Amble ‘padding’.
The Scan Groups fields and the second set of Scan Parameters fields defined by the Geo SCADA Expert advanced driver model are not used by the Geo SCADA Expert IEC 60870-5 driver. Any configuration in these fields is ignored by Geo SCADA Expert.
For information on configuring the fields on the Connection tab, see IEC 60870-5-101, or see IEC 60870-5-104, as appropriate.
The fields on the other tabs are common to channels on many advanced drivers—for information, see Tabs on Channel Forms in the Geo SCADA Expert Guide to Advanced Drivers.
