Producing A .Dbc File - ECM appsCAN Module Instruction Manual

A .dbc file describes to the device communicating from one or more appsCAN what is in the
data packages. For each module, the packages will contain data for the parameters selected
in the activated TPDOs, RPDOs, and an error code. The Configuration Software has a tool
called "Generate .dbc..." that will generate a .dbc file for all the modules on a CAN bus.
Make sure that each module is configured as desired and that all modules are on the bus
before the "Generate .dbc..." button is pushed. Data package information from all the
modules is stored in the one .dbc file produced.
Programs importing the .dbc file and applying it to the CAN data transmitted by the modules
will see data, etc identified as follows:
Data: name_nid[units]
where: name = parameter name. See Table 2.
nid = node id of module in hex
units = units of parameter
for example: VRF1_0X01[%] which is the Voltage Reference #1 voltage measured by
module with nid 0X01
Error code: ECM_Error_Code_nid
where nid = node id of module hex
error code is in hex and given in Table 3
for example: ECM_Error_Code_0x11
Auxiliary: ECM_Auxiliary _time[sec]
where: time = decrementing countdown to module activation in hex
for example: ECM_Auxiliary_0X12[sec]
12
