Diagnostic LEDs for Ethernet/IP

After switching on, the Fieldbus Box  immediately checks the connected configuration. Error-free start-up is indicated when the red I/O ERR LED goes out. If the I/O ERR LED blinks, an error in the area of the Inputs/Outputs is indicated. The error code can be determined from the frequency and number of blinks. This permits rapid rectification of the error.

The module has two groups of LEDs for the display of status.
The upper group with four LEDs indicates the status of the respective fieldbus. The significance of the fieldbus status LEDs is explained in the appropriate sections of this manual. It corresponds to the usual fieldbus display.

At the lower end of the module are two more green LEDs that indicate the supply voltage. The left hand LED indicates the presence of the 24 VDC supply for the Fieldbus Box. The right hand LED indicates the presence of the supply to the power contacts.
