11. Appendix A - Sensor Reset
10.1 Step 1: Ground pins 2 and 4
In the event that the IP address has been configured on a sensor, but
that IP address has been lost or forgotten. It will be necessary to re-
set the EtherNet/IP sensor back to DHCP mode so that a new IP ad-
dress can be assigned. This is accomplished by using the 4 pins lo-
cated on the M8 input voltage connector.

To begin the reset to DHCP, connect pin 1 to +24 VDC and connect
pins 2, 3 and 4 to ground.

10.2 Step 2: Float Pins 2 and 4
After approximately 5 seconds, the In and Out Port Traffic LED’s
will both light up red. cause material damage are highlighted by the
preceding pictogram, which is defined below.
After the LED’s turn red, remove pins 2 and 4 from ground and let
them float again. The In and Out Port LED’s will turn off.

10.3 Step 3: Ground Pins 2 and 4
After approximately 5 seconds of allowing pins 2 and 4 to float, the In
and Out Port LED’s will again turn red. After the In and Out Port LED’s
are red, reconnect pins 2 and 4 to ground. The Module Status LED
will change from green to red and then begin to flash green. The sen-
sor no longer has a fixed IP address and is back in DHCP mode.
