5.2 Network management (NMT)
Via network management, the master is able to make status changes for the entire CAN network.
Communication phases
Status Explanation
"Initialisation"
(Initialisation)
After the I/O system has been switched on, the initialisation is carried out.
During this phase, the I/O system is not involved in the data transfer on the
bus.
Furthermore, it is possible in every NMT state to carry out a part of the
initialisation or the entire initialisation again by transmitting various
telegrams (see "State transitions"). During this process, all parameters that
have already been set receive their standard values again.
After the initialisation is complete, the I/O system is automatically in the
"Pre-Operational" state.
"Pre-Operational"
(before being ready for operation)
The I/O system is able to receive parameter data.
The process data are ignored.
"Operational"
(ready for operation)
The I/O system is able to receive parameter data and process data.
"Stopped"
(stopped)
Only network management telegrams can be received. Parameter data and
process data are not received.
The module outputs switch to the configured status (see chapter
"Monitoring").
