6.1.4 Re-initialisation of the inclination sensor
If a node is not operating properly, it is advisable to carry out a re-initialisation�
After re-initialisation, the inclination sensor accesses the bus in pre-operational
mode�
Identifier Byte 0 Byte 1 Meaning
0h 82h 00h Reset communication
0h 082h NN (in hex) Reset node
Polled mode
By a Remote Transmission Request Telegram, the connected host calls for the
current process value� The inclination sensor uses the current position value,
calculates eventually set-parameters and returns the obtained process value by
the same identifier�
Cyclic mode
The inclination sensor cyclically transmits the current process value, without being
called by the host� The cycle time can be programmed in milliseconds for values
between 1 ms and 65536 ms�
Sync mode
The inclination sensor answers with the current process value after receiving a
sync telegram� The parameter sync counter can be programmed to skip a certain
number of sync telegrams before answering again�
Heartbeat function
A node signals its communication status by cyclically transmitting a heartbeat
message� This message is received by one or any number of members (Heartbeat
Consumers) in the bus and so they can control the dedicated node (Heartbeat
Producer)�
6.2 Boot-up procedure
The general boot-up process and a mapping view of the different modes are illus-
trated below (boot-up message for node ID 10 = 70Ah)
Number Description
1 Module power-up
2 After initialisation, the module automatically goes into pre-operational mode
3 NMT: Start remote node
4 NMT: Pre-operational mode
5 NMT: Stop remote node
6 NMT: Reset node
7 NMT: Reset communication
