    tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

sNetId: A string containing the AMS network identifier of the PC.

bExecute: The block is activated by a rising edge at this input.

tTimeout: Maximum time allowed for the execution of the function block.

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.

dwAttribute: Supplies the Sercos parameter attribute.

fActualMainVoltage: Supplies the main voltage of the AX5000 (i.e. 303.0 means 303.0V ).
