MODBUS MESSAGE TABLE
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.
The MSGN being transmitted is a numerical value and must be interpreted by the communicating
device, which actually is an advantage since this can be made to be whatever message text the end
user wants. In other words, it allows for programming custom messages without actually changing
the message in the programmer. Refer to Table 7, for message information.
The BurnerLogix stores its burner on time (7 powered) and system on time (L1 powered) in minutes.
For display purposes, the programmer converts this to hours. The information being supplied by
Modbus will be the actual time in minutes and it is up to the communicating device to do the conver-
sion. Since the maximum value stored in the BurnerLogix is 9,999,999 minutes, the maximum value
in hex therefore is 98967FH and comprises two data words. The maximum cycle count is 999,999
decimal or F423FH, still two data words.
