This function block can be used to issue the following commands for controlling network initialization:

•Enabling base network initialization

•Starting base network initialization

•Aborting network initialization

•Starting or resuming network initialization

Basis network initialization

This performs basic initialization of the network connection to all drives in the system and boots all drives. This function is usually performed just once immediately after the PLC is booted.

Network initialization

Initializes the network connection to a drive and performs the following steps that have not yet been completed for this drive:

•Restarts and initializes the NC operating system for the ACOPOS drive.

•If parameters are defined for this ACOPOS drive in the hardware configuration (e.g. motor parameters, resolver parameters), then they will be transferred to the ACOPOS device.

•If an ACOPOS parameter table is defined in an NC mapping table for this ACOPOS drives, then the parameters in the table will be transferred to the ACOPOS device.

Information:

This functionality is not available for virtual axes. If it is called for a virtual axis, the function block will return error 29235: The functionality is not available for the current axis type.

Requirements for use

•Function block name for SG3/SGC target systems MC_097BR_NetworkInit

PLCopen axis states in which the function block is permitted to be enabled

All PLCopen axis states, no effect on the PLCopen axis state

Function block

mc_br_networkinit

Parameter

I/O	Parameter	Data type	Description
IN	Axis	UDINT	Axis reference Note: If constant mcALL_AXES is specified instead of an axis reference, the command affects all axes (basic network initialization).
IN	Execute	BOOL	Execution of the function block begins on a rising edge of this input.
IN	Command	UINT	Command •For axis reference mcSTOP ... Abort network initialization mcSTART ... Start network initialization •For mcALL_AXES mcENABLE ... Enable base network initialization mcSTART ... Start base type network initialization
OUT	Done	BOOL	Command executed
OUT	Busy	BOOL	The function block is active and must continue to be called.
OUT	Error	BOOL	Error during execution
OUT	ErrorID	UINT	Error numbers
