FB_SoEReadClassXDiag_ByDriveRef

FB_SoEReadClassXDiag_ByDriveRef 1:

With the FB_SoEReadClassXDiag_ByDriveRef function block the current class 1 diagnosis (S-0-0011) ... class 3 diagnosis (S-0-0013) can be read as WORD. For the evaluation of the class 1 diagnosis as structure ST_AX5000_C1D there is a conversion function F_ConvWordToSTAX5000C1D.

Name

Type

Description

stDriveRef

ST_DriveRef

Reference to the drive. The reference to the drive can be linked directly to the PLC in the System Manager. To do this, an instance of the structure ST_PlcDriveRef must be allocated and the NetID must be converted from the byte array into a string. (Type: ST_DriveRef)

bExecute

BOOL

The function block is enabled via a positive edge at this input.

iDiagClass

USINT

Specifies which diagnosis should be read. The diagnostics parameters may vary from vendor to vendor. All diagnostics parameters (C1D ... C3D) or all bits are not always implemented in them.

1: Error: Class 1 Diag (S-0-0011)

2: Warnings: Class 2 Diag (S-0-0012)

3: Information: Class 3 Diag (S-0-0013)

tTimeout

TIME

Maximum time allowed for the execution of the function block.

Name

Type

Description

bBusy

BOOL

This output is set when the function block is activated, and remains set until a feedback is received.

bError

BOOL

This output is set after the bBusy output has been reset when an error occurs in the transmission of the command.

iAdsErrId

UINT

In the case of a set bError output returns the ADS error code of the last executed command.

iSercosErrId

UINT

In the case of a set bError output returns the Sercos error of the last executed command.

dwAttribute

DWORD

Returns the attributes of the Sercos parameter.

wClassXDiag

WORD

Returns the current Class X diagnosis.
