IQ 250S D: DNP Map
D.5: Error Reply
In the case of an unsupported function, or any other recognizable error, an error reply is generated
from the IQ 250S meter to the Primary station (the requester). The Internal Indicator field will
report the type of error: unsupported function or bad parameter.
The broadcast acknowledge and restart bit are also signaled in the Internal Indicator field, but they
do not indicate an error condition.
