• Make sure the control linkage has been reattached and all cables have been recon- nected. • Make sure all safety devices of the installation are in perfect order and are working properly! Triton OMD CAN protocol / Rev.-No. 03... -
Page 11: System 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. - Page 12 2 System description Triton OMD CAN protocol / Rev.-No. 03...

3 HEINZMANN CAN protocol 3 HEINZMANN CAN protocol HEINZMANN CAN protocol is based on the CAN specification 2.0B with 29 bit identifier. The identifier contains information about sender and receiver and the command code. Maximum 8 data bytes are therefore available completely for operative data. -

Tab. 3.2 Identifier template 3.4 Node numbers For each device type in the HEINZMANN CAN network each node number in the range be- tween 1 and 31 must be assigned only once. Node number 0 is not allowed for a single device, since it is used as the number for messages to all nodes of a certain type. -
