"DefaultCouplingMaster" methods - overview
9.4.3 The "DisableDefaultCouplingSlave" function
The "DisableDefaultCouplingSlave" function has the effect that the slave module decouples from
the state machine of the master module (during operation).
• This function is required if...
• ...specific machine parts / machine modules are to be decoupled (during operation).
• ...a different response is required for the decoupled machine parts/machine modules than for
the higher-level machine module.
• The SMDisableDefaultCouplingSlave(TRUE) method call of a module application (MAP)
activates the function to decouple the slave from the master.
• The SMDisableDefaultCouplingSlave(FALSE) method call deactivates the function.
• The module's intrinsic state machine cannot be coupled to the higher-level master module.
• The state machine can control the subordinated slave modules (locally from the module
application) via the BaseChannel methods.
• That way, the MFB_MachineControl state machine of the lower-level slave modules acts just
like the machine module with the activated SMDisableDefaultCouplingSlave method.
• The higher-level master module ignores the status of a slave module for which the
DisableDefaultCouplingSlave function is activated.
• Optionally, the error acknowledgement can be set via the higher-level master:
Identifier/function Transfer value/data type Description
baseChannelGetDefaultCouplingMaster
Disabled
• Queries the status of the
SMDisableDefaultCouplingMaster
method of the respective module.
MM_Address
L_EATP_MM_Address
• Address of the module the current
state of which is to be queried.
• The value "0" and the
L_EATP_CONST.OWNID constant
address the module's intrinsic ID.
Return value/data type
BOOL
• TRUE: of the master is
deactivated
• FALSE: The standard coupling of
the master is activated.
SMDisableDefaultCouplingMaster
• Activates/deactivates the standard
coupling of the master.
xValue
BOOL
• TRUE: Deactivate the standard
coupling of the master
• FALSE: Activate the standard
coupling of the master
