6.9.1
NMT_CS_NOT_ACTIVE
is a non-permanent state which allows a starting node
to recognize the current network state. The MS (Module Status) LED is off.
The CN observes network traffic. The node is not authorised to send frames
autonomously. There is no Legacy Ethernet frame transmission allowed at
. The node is able to recognize
NMTReset
commands
sent via Asnd.
The
transition
from
to
is triggered by a SoA or SoC frame being
triggered by timeout for SoC, PReq, PRes and SoA frames.
6.9.2
NMT_CS_PRE_OPERATIONAL_1
, the CN sends a frame only if the
MN has authorised it to do so by a SoA AsyncInvite command. The MS (Module
Status) LED gives single green flashes.
In
the node is identified by the MN via
IdentRequest
. If required the CN downloads its configuration data from a
configuration server. Both processes may be completely or partially shifted to
, if the MN is not in
before the CN has completed its configuration.
The transition from
triggered by a SoC frame being received.
There is no PDO communication in
6.9.3
NMT_CS_PRE_OPERATIONAL_2
, the CN waits for the
configuration to be completed. The MS (Module Status) LED gives double green
flashes.
The node is queried by the MN via PReq. The received PDO data may be invalid.
The PDO data received from the MN via PReq and from other CNs and the MN
via PRes is ignored by the CN.
CNs respond to
AsyncInvite
commands via SoA. If not invited by the MN, there
is no Ethernet frame transmission allowed at the
state.
Precondition for the transition from
is the reception of an
NMTEnableReadyToOperate
command. The transition is triggered if the
application is ready for operation.
The
transition
from
to
is triggered by an error recognition.
triggered by reception of NMT state command
