For applications with few PIDs, commission the existing application and record to keep track of the values for the PID-Pre and PID on paper or by using a program such as Microsoft® Word or Excel®.
For applications with larger quantities of PIDs, we recommend that you create an attribute template and use Read/Write Attributes Online to get the values from the pre-upgraded controllers and then to write those values back once the upgrade is completed.
To confirm that you have all of the PIDs, you can use Release Mode 10.2 / Firmware 6.2 and the BACnet Exposed tab to find all instances of a type of objects (even with old applications).
- Open the CAF in the software.
- Navigate to the BACnet Exposed tab.
- Under Settings, check Show All and Show BACoids.
- In the Filter field, search for the text of the object type. If the entire object type text is known, end the filter with a colon to narrow down the results (Ex. PID:).
