6.4 Connection Monitoring by the JX3 System
Bus
Between the JX3-BN-CAN and the connected JX3 modules, telegrams are regularly
exchanged via JX3 system bus. The bus head JX3-BN-CAN and the JX3-BN-CAN
module can detect an interrupted connection this way. An interrupted connection can be
restored by restarting the JX3 system bus.
Occasionally, the JX3-BN-CAN bus head stops data exchange with the connected JX3
modules.
•
The JX3-BN-CAN bus head is not connected with the superordinate controller any
more.
• The JX3-BN-CAN bus head has recognized an internal error.
Important!
If data exchange within the JX3 system bus has been stopped, the JX3 modules
write the configured error statuses to the outputs.
6.5 Electronic Data Sheet (EDS)
In the individual JX3 modules, various product relevant data have been stored to a
remanent memory. These include serial number, hardware version, etc. All data have
been combined in the so-called Electronic Data Sheet (EDS).
