KNX Modbus Gateway LEDs
There are three LEDs on the front of the KNX Modbus gateway (RP-C-EXT-KNX) and one LED above the front. The LEDs indicate different types of status and modes.

- The indicator comprises two LEDs, green and red, in one structure. When both LEDs are switched on at the same time, the colors blend and the result is amber (orange) light.
The LEDs indicate the status of the device, the programming mode, and the status of the KNX and Modbus RTU communication on the KNX bus and RP-C Modbus (RS-485) network respectively.
Programming LED
The Programming LED indicates whether the programming mode is active for the device.

Device is not loaded correctly (for example, because an ETS download was interrupted). b |
Download application from ETS again. |
|
No light |
No power supply from the KNX bus connection. |
Check the KNX bus connection. |
