6 LED Indicators & Trouble-shooting
There are two LED indicators on DVPPF02-H2, POWER LED and NET LED. POWER LED displays
whether the power supply of DVPPF02-H2 is normal. NET LED displays whether the communication of
DVPPF02-H2 is connected normally.
POWER LED
LED status Indication How to correct
Green light steady on The power is normal. --
Off No power
1. Check if the power of DVP-EH2 is normal.
2. Check if the connection between
DVPPF02-H2 and DVP-EH2 is normal.
NET LED
LED status Indication How to correct
Off No power
1. Check if the power of DVP-EH2 is normal.
2. Check if the connection between
DVPPF02-H2 and DVP-EH2 is normal.
Red light steady on
DVPPF02-H2 is operating but
is not connected to
PROFIBUS DP network.
Check if DVPPF02-H2 is normally connected to
