the control rights or in the

interruption of the bus adapter
Behaviour in case bit 10 in the control word of the bus adapter is cancelled or when interrupting the communication between con-
verter and bus adapter (see also P182). Here it is assumed that the respective bus adapters perform a cyclic communication on
the USS side, so that the respective converter electronics is capable of detecting a communication interruption
The bits in parameter 179 represent an equivalent to the control word in the USS protocol.
The actions linked to these bits are run provided bit 10 in the control word (USS protocol for bus adapter) is cancelled or if there
are interruptions in the communication between converter and bus adapter.
Here bit 10 is of special significance:
Bit 10 = 0 The control rights are returned to the next lower priority level. All other bits are not relevant.
Bit 10 = 1 The control rights remain unchanged. The actions linked to the other bits are run.

control rights of the bus
adapter and time-out in the
case of a communication
interruption
Defines the time characteristic when cancelling bit 10 in the control word of the USS protocol or when an interruption in the com-
munication between bus adapter and converter and electronics is detected. Handling when cancelling bit 10 or when there is an
interruption on the communication side of the USS bus adapter, is the same.
Value 0.0: Indefinite time delay. In this way a change of the control right is inhibited.
Values 0.1 ..6553.5: A change in the control right corresponding to the setting of parameter 179 is only effected after the time
span defined through parameter 182 has elapsed.
