Modbus TCP Profile

[jmir]

Hi,

Are offsets applied to write function when you define them on the profile? 

It seems that using the code below it reads from holding register 6 but writes on register 0...

Code:

       {"name": "Test_Register",
    "bus_datatype": "int16",
    "type": "register",
    "datatype": "int16",
    "address": 0,
    "read_offset": 6,
    "read_count": 20,
    "bus_address": "33/1/7",    
    "writable": 1,
    "value_delta": 1,
    "value_multiplier": 1,
    "units": "",    
    },

We need to read using blocks and on this blocks there are some writable registers...
Is there any way to solve it?



Thanks.

In RC3 firmware writing with block read is not working. We added this functionality recently. What is your hardware?

Status object is the connection statuts?
Are other new features using this package?

Thanks!

Yes, status object changes whether the modbus slave is accessible or not. No other new features, just some minor improvements and bug fixes.
