Check the following items.
Item
Is the BF LED on the NZ2FT-PBV off?
Is the voltage of the power supply (24VDC) of the
NZ2FT-PBV within the specified range?
Is the wiring between the DP-Master and NZ2FT-
PBV appropriate?
Are the parameters correct?
If communication is not established with the DP-Master even after checking all of the above and checking with the LEDs of the
I/O module and Web server, there is a risk of hardware failure in the NZ2FT-PBV.
