IOF_SER_DRIVE_Reset 1:

The function block "IOF_SER_DRIVE_Reset" performs a drive reset of a SERCOS drive. The drive errors are cleared.

Internally, an instance of the ADSWRITE function block is called.

VAR_INPUT

VAR_INPUT
    sNetId      : T_AmsNetId;
    nPort       : UINT;
    bReset      : BOOL;
    tTimeout    : TIME;
END_VAR

sNetId: It is possible here to provide the AmsNetId of the TwinCAT computer on which the ADS command is to be executed. If it is to be run on the local computer, an empty string can be entered.

nPort: The port number nPort is specified by the TwinCAT System Manager during the hardware configuration.

bReset: The function block is activated by a positive edge at this input.

tTimeout: States the length of the timeout that may not be exceeded by execution of the ADS command.

VAR_OUTPUT

VAR_OUTPUT
    bBusy          : BOOL;
    bError         : BOOL;
    nErrId         : UDINT;
END_VAR

bBusy: When the function block is activated this output is set. It remains set until and acknowledgement is received.

bError: If an ADS error should occur during the transfer of the command, then this output is set once the bBusy output is reset.

nErrId: Supplies the ADS error number when the bError output is set.
