PN_SystemWriteCmds (PROFINET IO)

The following tables give information about the parameters of the function block interface.

Input	Data Type	Description	Variable Category
i_xEnable	BOOL	Activates the function block processing. Cyclic data will be read/written to the hardware IO interface.	Function block control
i_xAcyclicBusy	BOOL	Can be used to block the acyclic execution if acyclic communication of another function block is active.	Function block control
i_xExecute	BOOL	Starts an acyclic request on a rising edge.	Function block control
i_uiNoConfAvatar	UINT	Used to parameterize the number of configured avatars to define the length of the data, which needs to be written. Minimum value is 0 (only Bus coupler) and maximum value is 20.	Function block control
i_udtAcyclicWriteCmds	UDT_SystemWriteCmds	This is a structure of acyclic system write data, which includes reset commands and energy data of the system and all avatars. For detailed information about the structure of this UDT, see UDT_SystemWriteCmds.	Acyclic data
i_hwSubmHWID	HW_IO	Must correspond to the hardware identifier of the acyclic submodule of the related avatar to be able to execute the acyclic communication.	Communication parameter

Output	Data Type	Description	Variable Category
q_xActive	BOOL	If this output is set to TRUE, the Avatar function block is enabled, or an acyclic request is busy.	Function block status
q_xError	BOOL	If this output is set to TRUE, a detected error occurred while executing the Avatar function block. For detailed information about the detected error, see the value of the Error ID.	Function block status
q_dwErrorID	DWORD	The Error ID shows detailed information about the detected error that occurred. Possible values are shown in the table below.	Function block status
q_dwAcyclicStatus	DWORD	The Acyclic status provides detailed information about the acyclic fieldbus communication, including detected error details. For detailed information about the status values, see Function Block Library.	Function block status
q_xAcyclicBusy	BOOL	If this output is set to TRUE, an acyclic request is still busy.	Function block status
