System description
2.1
Proper and intended use
CAN protocol, discussed in this document, is used for internode communication in OMD
network. The network can consist of one master device (OMD evaluator or superordinate sys-
tem) and up to 16 OMD sensor devices.
2.2
Functional description
Communication in the OMD network is based on the following key functions:
•
HEINZMANN CAN protocol is used for internode communication within the network.
•
Each device in the network has its unique ID which is used as node number item of
CAN telegram identifiers.
•
Automatic ID assignment procedure is used to start communication within the network
after system power up.
•
After successful ID assignment, sequence for checking of operational parameters set
consistency of all OMD sensors on bus is foreseen. If required, master device broad-
casts valid parameter set to the OMD sensors.
•
Only after successful ID definition and operational parameter set matching, OMD sen-
sors broadcast own operational data.
