Description
Depending on its NMT command entries, CANOPEN_NMTSERVICES either triggers an NMT
command or the initialisation of a node.
NMT = Network-ManagemenT

ifm function elements for the device CR0403
Description
FALSE  TRUE (edge):
execute function element once
otherwise: function element is not active
A function element already started is processed.
CAN interface (1...n) depending on the device
node ID = ID of the node (0...127 )

NODEID = 0:
command is valid for all nodes connected to the network
NODEID = node ID of the device:
command is valid for the device itself
network command
0 = init node (except master)
1 = enter PRE-OPERATIONAL
2 = start node
3 = reset node
4 = reset communication
5 = stop node
waiting time of the FB for the initialisation
when the time has elapsed, the FB stops waiting.
0 = use value from the configuration
