| Library_File_Name | Diag_AC500_V10.lib |
| Firmware | V1.0.2 |
| Type | Type_Function_Block_History |
| Group | - |
The Function Block CS31_DIAG provides the diagnosis data of the CS31 bus to the user.
The instance diagCS31 of the Function Block CS31_DIAG is declared in the global variables list GL_AC500_Diagnosis. The integrated visualization of the Function Block accesses the variables of this instance.
In order to include the Function Block into an AC500 project, it is only necessary to call the Function Block instance. Example in ST:
diagCS31(EN := TRUE, COM := 1);
The read values are written into internal structures of the instance diagCS31.
| Structure | TYPE | Assignment |
|---|---|---|
| strVisuData1 | strCS31_DiagBus | Diagnosis data of the CS31 master |
| strVisuData | strCS31_DiagModule | Diagnosis data of all 31 CS31 software modules ARRAY[0..31] OF strCS31_DiagOneModule |
| CS31Mod | strCS31_DiagOneModule | Diagnosis data of one CS31 software module |
The structure strCS31_DiagBus is composed as follows:

byStateDiag = 0 : no diagnosis Bit 0 (0x01, 1) : a device that was present on the bus has been disconnected from the bus.

The structure strCS31_DiagModule contains an ARRAY[0..31], i.e. with 32 entries of the structure strCS31_DiagOneModule.
This way, the structures strVisuData1 and strVisuData provide access to all diagnosis data of the CS31 bus.
If the user program should have access to these values, this is done as follows:
diagCS31.strVisuData1.Variable.
In the following example, the current number of CS31 modules is read and assigned to the variable byActNumCS31Module:
The most important data are available in the visualization Visu_CS31_Diag of the Function Block Visualizations.
