Specify any SCADAPack x70 Logic Requirements

The SCADAPack x70 tab on the Forms of SCADAPack x70 Analog, Digital, and Counter Configuration items contains a Logic section. You only need to configure the properties in this section if the point is to be used in an IEC 61131-3 application that customizes the SCADAPack x70 device operation. If so, you use the SCADAPack x70 Logic Editor provided with SCADAPack RemoteConnect configuration software to develop the required IEC 61131-3 application.

The Logic section contains the following properties:

• Logic Variable Type—Use to specify the pre-defined logic variable with which the point is associated. The default is 'None'; the other options vary, depending on the point type.
  • None—Use for points that provide system information, status information, or counter information and are not used in SCADAPack x70 logic.
  • Analogs:
    • T_SPx70_INT
    • T_SPx70_UINT
    • T_SPx70_DINT
    • T_SPx70_REAL
    • T_SPx70_ADV_ANALOG
  • Digitals:
    • T_SPx70_ADV_DIGITAL
    • T_SPx70_BOOL
  • Counters:
    • T_SPx70_UDINT
    • T_SPx70_ADV_COUNTER

  For information about the attributes that are exposed with each logic variable type, see the documentation provided with the SCADAPack x70 Logic Editor. (The Logic Editor is supplied with SCADAPack RemoteConnect configuration software).

• Logic Task—Use to specify the logic task in which the input acquisition or the output update takes place. Choose from:
  • MAST—The master task that typically executes the majority of logic in the IEC 61131-3 application.
  • FAST—An optional time-triggered task that executes short duration time-sensitive logic at a higher priority than the MAST tasks.
  • AUX0—An optional auxiliary task that executes slower, less important background logic at a lower priority than logic in the MAST tasks.
  • AUX1—An optional auxiliary task that executes slower, less important background logic at a lower priority than logic in the MAST or AUX0 tasks.

  For more information about the task types, task execution phases, and so on, see the documentation provided with the SCADAPack x70 Logic Editor. (The Logic Editor is supplied with SCADAPack RemoteConnect configuration software).

• Exclusive Logic Control—Select this check box if the point is to be under the exclusive control of the logic application. Only the IEC 61131-3 application can update the point; requests from other sources (such as ClearSCADA) are blocked.

  Clear the check box (the default) for the point to be written to from multiple sources. For example, from a SCADA master (such as ClearSCADA), or an IEC 61131-3 logic application.
