11.2 Reset the connection set (OD index 1011h)
The saved communication profile (OD index 1000h - 1FFFh) can be reset to
the factory settings via the entry 1011h/01h by writing the command "load"
(64616F6Ch) in this entry. After a "reset application" (NMT command) or a
hardware reset the changes become effective. If a "reset communication" (NMT
command) is transmitted, the factory settings of the communication parameters
become effective.
11.3 Factory reset (SDO index 207Fh)
To reset the manufacturer-specific parameters of the inclination sensor (SDO
index 2000h – 5FFFh) to the factory settings the value 1 has to be written to the
respective parameter (SDO index 207Fh).
If the value 1 is read when this parameter is read, the factory reset was successful.
If the value 0 is read, the factory reset failed.
The factory reset also applies to the settings of the communication protocol (CiA
DS-301), for example the node ID or the baud rate. If the node ID or the baud rate
was changed, the changes only become effective after a reset of the device.
The data of the factory setting (node ID = 10, baud rate = 125 Kbits) are only valid
again after this reset.
12 Emergency messages
Every inclination sensor supports EMCY messages which are transmitted in the
event of sensor, temperature, hardware or guarding errors.
If one of these errors occurs, the error register (OD index 1001h) and the pre-
defined error field (OD index 1003h) are updated.
After rectification of the error the device transmits an EMCY message with the
"error reset" code (0h) and the current state of the error and manufacturer status
register. The current device state ("pre-operational, operational or stopped") is not
influenced by the error states (except for guarding errors).
12.1 Failure monitoring
As in a CANopen network the nodes do not respond regularly in the case of
an event-controlled transmission, heartbeat and node guarding/life guarding
mechanisms are available for failure monitoring.
Only one of the two monitoring methods can be used.
12.1.1 Node guarding / life guarding
Node guarding is the monitoring of one or several nodes by the NMT master.
The NMT master periodically transmits an RTR telegram to the slave to be
monitored which responds with its own status and a toggle bit.
