Create System Functions

The OPC import data does not automatically generate system functions (schedulers, or trends). They must be manually created after a data import, based on the most current project SX Open configuration file, if:

  • Entries are available in the Schedules tab;
  • Entries are available in the Trend tab;
  • Entries are available in the Configuration tab (the BACnet alarm info column). They must be checked.

Create Management Station Event for OPC Devices

  • You imported a CSV file.
  1. Select Project > Subsystem networks > [OPC network].
  1. Select the data point to configure the management station event.
  • The alarm details are displayed in the Alarm configuration expander in the Configurator tab.

Additional information on creating events is available in Step-by-step > Configuring a Project > Configuration Workflows & Procedures > Configuring Objects:

  • Creating a Continuous Alarm
  • Creating a BitString Alarm

Create a Scheduler Program

Scenario: You want to create a weekly schedule for an OPC object. The times used in the example must be synchronized against the actual project times.

  • You imported a CSV file.
  • The number of schedules to be created is based on existing schedule available in the Excel worksheet in the Schedules tab.
  1. In System Browser, select Application View.
  1. Select Applications > Schedules.
