FB_SoEAX5000ReadActMainVoltage

With the FB_SoEAX5000ReadActMainVoltage function block the current peak value of the mains voltage of the AX5000 (P-0-0200) can be read.

Inputs

VAR_INPUT
    NetId   : T_AmsNetID := '';
    Execute : BOOL;
    Timeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

Name	Type	Description
NetId	T_AmsNetID	String which contains the AMS Network ID of the PC (type: T_AmsNetId).
Execute	BOOL	The function block is enabled via a positive edge at this input.
Timeout	TIME	Maximum time allowed for the execution of the function block.

Inputs/outputs

VAR_IN_OUT
   Axis : AXIS_REF;
END_VAR

Name	Type	Description
Axis	AXIS_REF	Axis data structure that unambiguously addresses an axis in the system. Among other parameters it contains the current axis status, including position, velocity or error state.

Outputs

VAR_OUTPUT
    Busy              : BOOL;
    Error             : BOOL;
    AdsErrId          : UINT;
    SercosErrId       : UINT;
    Attribute         : DWORD;
    ActualMainVoltage : LREAL;
END_VAR

Name	Type	Description
Busy	BOOL	This output is set when the function block is activated, and remains set until a feedback is received.
Error	BOOL	This output is set after the Busy output has been reset when an error occurs in the transmission of the command.
AdsErrId	UINT	In the case of a set Error output returns the ADS error code of the last executed command.
SercosErrId	UINT	In the case of a set Error output returns the Sercos error of the last executed command.
Attributes	DWORD	Returns the attributes of the Sercos parameter.
ActualMainVoltage	LREAL	Returns the peak value of the current mains voltage of the AX5000 (e.g. 303.0 corresponds to 303.0 V).
