Using Data Points in IEC 61131-3 editor

To map the IEC 60870-5-104 Data Points to IEC 61131-3 editor, use IEC 60870-5-104 Function Block Library (see IEC60870 Library: IEC60870 Library

The created Data Points which are available at the global variable list have to be assigned to the corresponding Input of the Function Blocks of the IEC 60870 Library. See Creating configuration data: Creating Configuration Data

For each Data Point group type an equivalent function block type in IEC60870 Library exists.

The implemented functionality of the IEC 60870-5-104 plug-in has the following characteristics:

• Unique names: Names of all connections (Substation and Control Station) and all names of the data groups are unique
• Unique addresses: All telecontrol addresses (consist of GADU1, GADU2, IA1, IA2, IA3) have to be unique within one telecontrol connection (all knots beneath 1 connection knot)
• Aliases: For the project planning the plug-in generates constant data structure aliases as global variables (read only)

For each created connection (Substation / Control Station) at the Automation_Builder the plug-in generates 1 data point in IEC 61131-3 editor.

Example

VAR_GLOBAL CONSTANT

Rec_sp_inf_16 : IEC60870_SinglePointInformation:=(Slot:=0, Con:=0, Idx:=17, NoDP:=1);
