15
Table 1:
It is suggested that polling intervals not be less than 200 mSec per request. Requesting data
such as burner minutes, system minutes and burner cycles should be kept at a minimum due to
the amount of processing time required to gather that data.
Messages 00, 05, 08, 10, 15, 21 and 26 are unique in that a limited number of successive registers
can be combined with these requests. For example, a request to message 00 can contain up to 6 data
words. The response to this would contain STATUS, MSGN, GSTAT, TIMER, FLAME and
LOGSTAT. If the requested data word count (DAT) were to be 2 then the response would contain
STATUS and MSGN only. Message 15, last 6 lockouts, can return data ranging from 1 to 6, with 1
referring to the most recent lockout.
