6.4 Fieldbus Indicating LEDs
All WI-GTWY-9-xxx modules (except MD1) are equipped with four fieldbus indication LED's
located in the module end plate, used for diagnostics purposes. The meaning of the LED’s for
each fieldbus is described below.
6.4.1 Ethernet Indicating LED’s
The WI-GTWY-9-ET1 module can communicate Modbus TCP or EtherNet IP
based protocols. The LED sequence will vary depending on Protocol being used and Ethernet
Board firmware.
Changes to Ethernet Board firmware effect LED 2 indications when flashing. When flashing this
only indicates that an EtherNet IP connection has not been made to the WI-GTWY-9-ET1.
Example would be RSLogix has not had a Generic Ethernet Device added with WI-GTWY-9-
ET1 IP address and connection data.
If using Modbus TCP then LED’s 2 & 3 have no function in regards to the Modbus TCP
communications of the module
