Configuring the maintenance stations
5.13 Configuring the user diagnostics
Note
You can use the user diagnostics in the MS Standard version only.
User diagnostic structure
In the plant hierarchy, you can create one other hierarchy folder under the "Diagnostics"
hierarchy folder and additional hierarchy subfolders under this hierarchy folder to build a user
diagnostic structure based on technological aspects.
In the user diagnostic structure, you can insert one self-created diagnostic screen and CFC
charts for each hierarchy folder.
You can incorporate buttons into the diagnostic screens for switching between the user-created
and automatically created diagnostic screens.
The diagnostics functions are performed with different blocks, for example AssetM, which are
integrated in the CFC charts.
Diagnostic function with the AssetM block
The "AssetM" block has the function of a substitute object and is used for monitoring
components without self-diagnostics.
You can use the "AssetM" block to monitor three analog values.
Each analog value can be monitored for limits.
The maintenance status is defined on the basis this limit, demanded or alarm defined
(implementation of traffic light function in accordance with NE 107 of NAMUR).
The following functions are also available to you here:
● 7 inputs for reporting a corresponding maintenance status
● 16 inputs for displaying detailed diagnostics information
● 1 input for the maintenance status
● 1 input for the signal status
Cascading the signal status of process values
By using the "MuxST" multiplex block, you can interconnect the signal status of different
process values weighted to the "AssetM" block. The signal status with the highest priority is
shown in the faceplate in process mode.
The signal status must correspond to the PA profile 3.x.
Cascading the maintenance status
By using the "MuxMST" multiplex block, you can interconnect the maintenance status of
different "AssetM" blocks to a higher level "AssetM" block. The maintenance status with the
highest priority is shown in the faceplate in process mode.
