- Define the global Array-Registers definitions available for all ABB Totalflow devices in this Ignition instance.
- This step can be skipped if not configuring the driver to poll for AAR data.
- Upload the Periodic Mappings for all ABB Totalflow devices in this Ignition instance.
- This step can be skipped if default mapping provided by the driver is ok.
- Create the base device connection to the ABB Totalflow device.
- Specify the subset of global Array-Register definitions that this specific ABB Totalflow device uses.
- This step can be skipped if not configuring the driver to poll for AAR data.
- Reconfigure device connection to enable polling for Alarms.
As en example, let's configure the driver to poll for get Alarms and disable polling for Events and History. First of all, alarms can come from two sources:
- Alarm flags in Periodic History Records (Array 250)
