Problem in reading 64Bit Modbus register of type 'Double' with MODRTU32
We have a problem with the Modbus driver MODRTU32, our client has to perform a pre-FAT of the project tomorrow,
This project is a DPM application (Diagnostic Performance and monitoring application); we have already succeeded with a previous project.
But for this project they changed the flow-computer (Modbus slave device); the flow computer which is Flow boss model (Emerson) is using 64 bit for ‘DOUBLE’ registries
I was not aware of it till now where I get the client’s test result;
Those registries are located at registry: 7000 / 7004 / 7008 / 7012
Could you advice us what to do to read those registries?
I will really appreciate a quick answer as the client is at this moment waiting from my suggestion to close those unexpected issues before tomorrow.
Thank you
Karim
