The Diagnostic function block provides a method to monitor device alerts from non-fieldbus assets. In modules, wire parameters or block outputs that indicate device health for non-fieldbus blocks to the Diagnostic block. The alerts from these diagnostic blocks are monitored by Inspect with InSight. The block sets the output value based on the values of the inputs. The block does not support modes. The inputs have the following values when true:
Each DIAG function block must have a unique name in the entire DeltaV system. It is recommended that you name the blocks for the asset they refer to. The unique names are important because the Device page of Inspect lists only the DIAG block name. If two or more DIAG blocks have the same name the information in Inspect will be misleading because operators cannot determine which block's information is being displayed.
Note that fieldbus blocks are monitored automatically and do not require Diagnostic blocks.
