General Error (BFM #29 Bit 0)

When a general error occurs (bit 0 = ON) the 32NT-DP tries to send the data of BFM #28 and
#29 as a static diagnosis message to the DP-master. In this case data can not be exchanged
with the DP-master. After bit 0 returns to OFF, the static diagnosis message is also reset.

External 24V Power Error (BFM #29 Bit 2)

If a 24V DC power supply failure occurs, this bit is ON. If this error occurs, check 24V DC
power supply of the 32NT-DP.
