LIN Bus Signal Monitoring (Applies to the DL850EV)
You can monitor CAN and LIN bus signals using the 720241 CAN & LIN bus monitor module. CAN and LIN bus
signal monitoring is available only on the DL850EV.
For details on the CAN bus signal monitoring feature, see “CAN Bus Signal Monitoring (Applies to the
DL850EV).”
This section explains the LIN bus signal monitoring feature.
The DL850EV uses the module to read the ISO-9141 signal, that is transferred on the LIN bus and then extracts
the specified portion of the LIN frame (LIN data), converts it to time series data, and displays its waveform. The
waveforms of up to 60 sub channels can be displayed. You can also use the LIN descriptor files (LDF) that are
described in the LIN configuration language specification to specify (define) LIN data.
For LIN bus signal monitoring using a CAN & LIN bus monitor module, the items that have to be set include
port settings, frame settings, data extraction conditions, sub channel display range, unit of measurement, trace
settings, and scaling.
• You can install up to two 720241 CAN & LIN bus monitor modules in slots 7 and 8. If you install this module
together with a 720240 CAN bus monitor module, you can still only install a total of two modules.
• The DL850EV requires the following processing times to read data frames transferred on the LIN bus. New
frames that the DL850EV receives during these processing times may be discarded.

Waveform Display (Display)
You can select whether to display each port’s input signal waveforms. Each port corresponds to one of the CH13
to CH16 keys.
• ON: Displays the waveform
• OFF: Does not display the waveform
