• The method call has no impact on the connection of the ACD structure of the respective
machine module.
• The master of the state machine can read out a decoupled module via the corresponding
baseChannelGetActualState methods.
 Accessing the state machine - the methods of the BaseChannel ( 131)
• The master of the respective state machine can read out the status of a decoupled module (via
the corresponding methods). The use of this mechanism is advisable if the module is provided
with at least one higher-level master module.
Error response - response for the occurrence of an error
• The DisableDefaultCouplingSlave method decouples the slave module from the state machine
of the master module; example: decoupling M1.2.2 from M1.2.
• The Quick stop error status of M1.2 has no impact on M1 and M1.1 (the M1.2 module is
decoupled from M1).
• The state machine of the master module M1 no longer has an impact on the module M1.2
(due to the decoupling).
• Error acknowledgement by the M1 master module no longer has an impact on M1.2 and its
slave modules.

: Error response to "Fault" status of M1.2.2 by
SMDisableDefaultCouplingSlave(xValue := TRUE);
Identifier/function Transfer value/data type Description
baseChannelGetDefaultCouplingSla
veDisabled
• Queries the status of the
DisableDefaultCouplingSlave
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: Deactivate the standard
coupling of the master.
• FALSE: Activate the standard
coupling of the master.
SMDisableDefaultCouplingSlave
• Activates/deactivates the
standard coupling of the slave.
xValue
BOOL
• TRUE: Deactivate the standard
coupling of the slave
• FALSE: Activate the standard
coupling of the slave
