FB_SoEReset_ByDriveRef
The functionblock FB_SoEReset_ByDriveRef can be used to execute a drive reset (S-0-0099). Drives with more than on channel may require a reset on all channels. The timeout time must be 10s, because the reset can take up to 10s.
An NC-Reset is not executed.
VAR_INPUT
VAR_INPUT
stDriveRef : ST_DriveRef;
bExecute : BOOL;
tTimeout : TIME := T#10s;
END_VAR
stDriveRef: The drive reference can be linked in the System Manager between PLC and drive. The link can be done to an instance of the ST_PlcDriveRef. The structure ST_PlcDriveRef contains the NetID as byte array. The byte array can be converted to a string. See ST_DriveRef.
bExecute: The block is activated by a rising edge at this input.
tTimeout: Maximum time allowed for the execution of the function block. The reset can take up to 10s.
VAR_OUTPUT
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iAdsErrId : UINT;
iSercosErrId : UINT;
END_VAR
bBusy: This output is set when the function block is activated and remains set until an acknowledgement is received.
bError: This output is set up after the bBusy output has been reset if there has been an error in transmission of the command.
iAdsErrId: Supplies the ADS error code associated with the most recently executed command if the bError output is set.
iSercosErrId: Supplies the Sercos error code associated with the most recently executed command if the bError output is set.
