FB_SoEReadDcBusVoltage
The functionblock FB_SoEReadDcBusVoltage can be used to read the DC-Bus-Voltage of the amplifier (S-0-0380).
VAR_INPUT

sNetId : T_AmsNetId := '';
bExecute : BOOL;
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.

Axis : NCTOPLC_AXLESTRUCT;(* reference to NC axis *)
END_VAR
Axis: Axis structure.
VAR_OUTPUT

bBusy : BOOL;
bError : BOOL;
iAdsErrId : UINT;
iSercosErrId : UINT;
fDcBusVoltage : REAL;
dwAttribute : DWORD;
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.
fDcBusVoltage: Supplies the DC-Bus-Voltage (i.e. 294.0 means 294.0V).
