10 Parameter (connection set) handling
The CAN identifiers (COB IDs) of the communication objects are determined
according to the pre-defined connection set with every reset (communication,
application and hardware reset) depending on the set node ID (SDO index 2000h).
Always make sure that the current parameters (connection set) always match the
current node ID.
The connection set always refers to the current node ID. Therefore set the node ID
to the requested value before saving the connection set.
If the node ID is changed after the connection set was saved, the connection set
first has to be reset to the factory settings (SDO-Index 1011h „load“). After saving
the connection set again, all COB IDs that are calculated with the node ID are
mapped again correctly.
10.1 Save the connection set (OD index 1010h)
Changes of parameters in the object directory are immediately active except for
the node ID (SDO index 2000h) and the baud rate (SDO index 2001h). To ensure
that the changed parameters of the communication profile (CiA DS-301) are active
even after a reset, they must be saved in the internal permanent memory (flash).
On delivery, the sensor is set to „autosave“. If the node ID and/or the baud rate is
changed, the sensor must be rebooted. After the reboot, the sensor can be found
under the new node ID and baud rate. The saved communication profile is called
pre-defined connection set.
10.2 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 comand) or a
hardware reset the changes will become effective. If only a "reset communication"
(NMT command) is transmitted, only the factory settings of the communication
parameters become effective.
10.3 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 some settings of the communication protocol (CiA
DS-301) such as the node ID or the baud rate. If the node ID or the baud rate was
changed, the changes will, however, 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.
