Scan Setup Configuration
Scan Setup Configuration Overview:
A single PGN can contain multiple bytes of parameter information. That information needs to be defined
for each PGN in order for the JCM to understand what PGN data is to be stored into the corresponding
%AIs. The PGN Configuration screen allows for entering the required information to create a data map
between PGN data value and %AI registers.
The Scan Setup Configuration depicts the Type , Starting Register , Ending Register, and Number of
Registers for the %AI registers. (See Standard Configuration for an explanation of these parameters.)
The Scan Setup Configuration is used to configure %AI registers. (The number of %AIs vary depending
on your Scan Table configuration.)
To add a %AI, enter a Starting Register number. Press the
Add button.
The following screen appears.
Figure 3.7 - PGN Configuration
%AI: Denotes the %AI register being configured (or deleted). This box is automatically updated by the
Configurator.
PGN :
In order for the OCS/RCS to communicate with an Engine Control Module, it is necessary to
consult the engine manufacturer’s user documentation to determine Parameter Group Numbers ( PGN )
and the definition for the words for each parameter.
SAE J1939 specifies a table of PGNs. A PGN is unique numeric identifier that is associated with a
specific parameter name. A PGN is used to define the parameter value(s) a device is requesting or the
parameter value(s) that a device is sending. (Requires a number to be entered between 0 through
65,536.)
These boxes are
automatically updated
by the Configurator.
To configure, enter the
PGN and Number of
Words expected by the
Engine Control Module.
Scan Method:
