Industrial Ethernet Protocol Indication

5.3
Each Ethernet port has a RJ45 female connector with two indicator LEDs. The green LED
indicates the link status and the yellow LED lights up in response to network activity.
For complete industrial Ethernet conformance, adding two bi-color (red/green) LEDs is
recommended for the target device. In addition, the recommended method for controlling
each LED is defined in each communications standard. Therefore, the host CPU that
processed the data via the R-IN32M3 Module needs to control multiple LEDs.
Major protocol status conditions are listed in the following Table 5.1.
