4. Diagnostics and useful information

4.1. Error diagnostics in fieldbus communication

In case the inclination sensor does not react via the CANbus, check all cable connections first.

If the cable connections are ok, test fielbus operation next. To do so you need a CAN monitor to record

CANopen communication and to map the telegrams .

Now the inclination sensor should give a BootUp message upon power off and on again.

If there is no BootUp message, check whether the baud rates of inclination sensor, CAN monitor and bus

system are in alignment.

If you have problems in establishing a connection to a user check Node- ID and baud rate.

The baud rate must be all the same. The Node- ID (identifier, address) must be within 1 and 127. Every

bus user must be assigned a unique Node-ID, i.e. by no means the same Node ID must be assigned

several times.

Node-ID and baud rate may also conveniently be assigned by LSS services.

4.2. Error diagnostics via fieldbus

The inclination sensor provides several objects and messages to indicate state or error state:

object 1001h: This object serves as error register for the device error state.

object 1003h: This object saves the last 8 error codes and warnings.

object emergency (80h + Node-ID): High-priority error message of a user including error code and error

SDO Abort Message: If SDO communication does not run properly the SDO response will come with an

abort code.

Object 1001h Error register

This register is indicating an existing device error together with its kind.

See separate object meaning

Object 1003h Predefined error field

In this object the last 8 error codes occurred out of the objects 6503h and 6505h are saved, the latest error as

entry in subindex 1, the most ancient error as entry in subindex 8.

Object Emergency

Error message of a user.
