FB_EcFoeOpen

Inputs

VAR_INPUT
    sNetId    : T_AmsNetId;
    nPort     : UINT;     
    sPathName : T_MaxString;
    dwPass    : DWORD;
    eMode     : E_EcFoeMode;
    bExecute  : BOOL; 
    tTimeout  : TIME := DEFAULT_ADS_TIMEOUT; 
END_VAR

sPathName

By default, only the filename (without filename extension) is extracted from the file path (e.g. 'c:\TwinCAT\FOE\Data.fwp') that was entered and used as the filename for the FoE protocol (in our example: 'Data'). From library version 3.3.12.0, filenames including the filename extension can also be used (in our example: 'Data.fwp').

Via the global boolean variable
Tc2_EtherCAT.bEcFoeOpenFileNameWithFileExt
the use of the filename extension can be enabled or disabled for all instances of the FB_EcFoeOpen function block. By default, the variable has the value FALSE (no filename extension). If you set the value to TRUE then the use of filename extensions is enabled.
Note that the FoE function blocks were originally used for firmware updates where no filename extension was used. If you want to update the firmware, you may have to make sure that the global variable has its original default value, i.e. FALSE.
