Greetings, all wise and all knowing list.
We have an application where data from a Carrier chiller needs to be =
brought into the I/A via a Micro I/A. The problem is that, per TAC, the =
Micro I/A will not read the extended Modbus registers (6 digit) 300000 to =
399999. It only reads 5 digit registers (ex. 30000 to 39999). The =
chiller only supplies register addresses in the extended range.
The FBM224 has the same limitation. The FBM 230 will support extended =
registers, but requires the 270 series controller.
There is no option to move the registers in the chiller. It's just a =
conversion module from BacNet to Modbus. =20
The chiller supports BacNet, so the BacNet to Modbus converter from =
Fieldserver may be an option.
Has anybody else out there ran into something like this?
Thanks and Regards,
