Chapter 1 Product Overview
Figure 2 - Base Mounting Adapters
When power is applied to the device, the module runs a self-test routine to
verify the health of its internal electronic components and the result of this test
is visible via a bicolor status indicator that is mounted inside the module but
visible from the top. In addition, this status indicator also displays if the device
is communicating with the IO-Link Master. For more information on these
results, see
Power On Self Test (POST) on page 43
