7. Switching between Setting and Measurement Mode
When measuring (acquiring) CAN bus data on a CAN bus module, you can insert other I/O modules in the
MW100 and perform measurements on them at the same time. However, when the CAN module is installed
in the MW100, the CAN settings are entered using dedicated setting software (CAN Bus Module
Configuration Tool) via external serial communications.
7.1.Measurement Mode (STATUS LED Lights)
Set the dip switch on the CAN bus module to Measurement mode, and acquire CAN bus data through the
CAN connector. CAN bus data is measured on the MW100 in the same manner as that of the other I/O
modules.
7.2.Setting Mode (STATUS LED Blinks at Approximately One-Second Intervals)
Set the dip switch on the CAN bus module to Setting mode, and enter the various settings on the module
using dedicated setting software (CAN Bus Module Configuration Tool) through the SERIAL connector.
CAN bus data cannot be measured while in Setting mode.
