If a totally automatic start of the stack is not wanted, the functionalities:
• Status change
• Start of the guarding
• Configuration via CMT
can be also executed at request for every node. The request always
happens via objects in the object directory.
The switch of the communication state of all nodes in the network
(including the local slaves) happens via the entry 1F82h in the local object
directory:
Subindex 0 has the value 128.
Subindex x (with x=1..127): Initiates the NMT service for nodes with Node ID x.
Subindex 128: Initiates NMT service for all nodes.
At write access, the wanted state is given as value.
