Module Control Services
Through Module Control Services, the NMT master controls the state of the NMT slaves. The state attribute is
one of the values {STOPPED, PRE-OPERATIONAL, OPERATIONAL and INITIALISING}. The Module Control
Services can be performed with a certain node or with all nodes simultaneously. The NMT master controls its
own NMT state machine via local services, which are implementation dependent.
