Support Questions / Re: Newby needing help on Addressing MODbusRTU

Thank you for the links. watched the youtube video and read the other posts. I also checked out the other RPi implementation of the triangle tube boiler. I feel more confused and less intelligent but I was able to get two of my readings so far. I will tinker with it further over the weekend and then mono it on my RPi.

You folks are awesome.

Support Questions / Newby needing help on Addressing MODbusRTU
« on: November 06, 2015, 06:27:16 AM »
I am brand new to this world. I just got a Triangle Tube Prestige Solo boiler installed in my house that supports Modbus on RS485. I downloaded what appears to be excellent documentation on the supported commands and registers. I assume that I am supposed to put the register address into the PLCAddressValue field to read the register. I am not sure if I am supposed to use the HEX or Decimal values and I tried both but it isn't working. I am sure that it is a very basic newbie question but I have not been able to find an answer.

An example would be the Boiler Flue Temperature which is an input register (DEC 04/HEX 0x4) with an address of DEC 771/HEX 0x0303. The Byte format is listed as LB:S8. What would I enter into the PLCAddressValue field to pull this data?

Thank you for your patience.
