POWERLINK Information
3.10.1.4 NMT_CS_READY_TO_OPERATE
With this state the CN signals its readiness to operation to the MN.
The CN responds via PRes when queried via PReq by the MN and is included into the
cyclic data exchange. However, the process input data, sent via PRes frames of the
measuring system to the MN, are defined as invalid by the RD flag.
The CN responds to AsyncInvite commands via SoA. If not invited by the MN,
there is no Ethernet frame transmission in this state.
The
length
NMT_CycleTiming_REC.PResActPayloadLimit_U16.
correspond to the requirements defined by the PDO mapping.
The transition from NMT_CS_READY_TO_OPERATE to NMT_CS_OPERATIONAL is
triggered by the reception of NMT state command NMTStartNode.
The transition from NMT_CS_READY_TO_OPERATE to NMT_CS_PRE_OPERATIONAL_1 is
triggered if an error is detected.
The transition from NMT_CS_READY_TO_OPERATE to NMT_CS_STOPPED is triggered
by reception of NMT state command NMTStopNode.
3.10.1.5 NMT_CS_OPERATIONAL
This is the normal operating state of the CN. Now, active process data exchange
between MN and CN over PReq and PRes messages is possible.
The CN responds to AsyncInvite commands via SoA. If not invited by the MN,
there is no standard Ethernet frame transmission in this state.
The
length
NMT_CycleTiming_REC.PResActPayloadLimit_U16.
correspond to the requirements defined by the PDO mapping.
The transition from NMT_CS_OPERATIONAL to NMT_CS_PRE_OPERATIONAL_2 is
triggered by the reception of NMT state command NMTEnterPreOperational2.
The transition from NMT_CS_OPERATIONAL to NMT_CS_PRE_OPERATIONAL_1 is triggered
if an error is detected.
The transition from NMT_CS_OPERATIONAL to NMT_CS_STOPPED is triggered by
reception of NMT state command NMTStopNode.
