IoDrvSercos3 (FB)

FUNCTION_BLOCK IoDrvSercos3 EXTENDS IoDrvBase IMPLEMENTS ICmpIoDrvParameter

The program organization unit IoDrvSercos3.

For each Sercos master an instance of POU IoDrvSercos3 is created. The properties may be accessed respecting the syntax “<Instance name>.<Property name”.

Examples of using the instance:

Restart of master:

SercosIII_Master.xRestart := xRestart

SercosIII_Master();

Call of master to retrieve information about the success of downloading the configuration parameters:

xFinish := SercosIII_Master.xConfigFinished;

InOut:

Scope	Name	Type	Comment
Input	xRestart	BOOL	A rising edge at this input will restart the master. All configuration data will be reloaded.
	wRequiredTopology	SERCOS_TOPOLOGY	The required topology (Ring, L1, L2 etc)
	xRecoverRingTopology	BOOL	If a ring topology is required and a ring break was detected then it is possible to recover the ring topology with this input.
Output	xConfigFinished	BOOL	If the output is TRUE, the transmission of all configuration data has been executed properly. The communication on the bus is in process.
	wState	WORD	The parameter wState has a value between 0 and 100 telling about the state of the initialization phase; the greater the value, the more the initialization process is advanced.
	wTopology	SERCOS_TOPOLOGY	The current topology of the Sercos III bus.
	xTopologyError	BOOL	IF wRequiredTopologiy is not equal to wTopology there is an error.
	xBusError	BOOL	If the bus is not working then this output is set to true
