Hello all, Hope someone reads this thread and can possibly offer some insight.
I have a question about the difference in protocol of return strings, sent from a modbus simulation software application, and an actual HCAV system harware return string.
I'm sending a poll request for 1 zone, 1 holding register,(temp value). I'm looking at the bitwize vlau information, of byte 5, and everything is working perfectly, and as it should when connected to the simulation software application, however when the same poll reqeust is send connected to an HVAC system hardware,( should be same protocol, I'm getting an incorrect value form the holding register.
Can anyone offer and information, or insight to this? please?
Thanks,
