Device Diagnostic
The 266 PdP FF produces different type of diagnostic information:
• Device Diagnostic
These are the diagnostic information produced by the Resource and Transducer Blocks and refer to the device status/health
• Process Diagnostic
These are the diagnostic information which are seen through process variable status and process alarms such as the HI, HI HI,
LO, LO LO, DV HI and DV LO alarms implemented in various Function blocks.
Scope of this section is to describe the Device Diagnostic to be consumed in the Asset Management Software.
