MC_AxParamAuxLabelsLoad_BkPlcMc (from V3.0)
The function block loads the label texts for the customer-specific axis parameters from a file. These texts can be generated with a simple text editor such as Microsoft Notepad.
 | The file must be structured according to the rules specified below. Otherwise, significant problems may occur, including system crash. |
This function block is generally not called directly by the application. If possible, a function block of type MC_AxUtiStandardInit_BkPlcMc should be used, which uses a function block of type MC_AxParamAuxLabelsLoad_BkPlcMc.

Name | Type | Description |

ErrorID | UDINT | An encoded indication of the cause of the error is provided here. |
Behavior of the function block
On a rising edge at Execute the function block checks the transferred axis interface. A number of problems can be detected and reported during this process:
- If one of the pointers has not been initialized the system responds with Error and ErrorID:=dwTcHydErrCdPtrPlcMc or dwTcHydErrCdPtrMcPlc.
The loading process begins if these checks are carried out without problems.
A falling edge at Execute clears all the pending output signals. If Execute is set to FALSE while the loading process is still active, the process that had started continues unaffected. The signals provided at the end of the operation (Error, ErrorID, Done) are made available for one cycle.
| The number of rows in the file must match the number specified in the global constants of the library as iTcHydfCustDataMaxIdx (currently: 20). The maximum number of characters in each row is 20 (included spaces, without line breaks). |
