When using the Modbus TCP/IP XDriver will the data type used by a 3rd party system be supported.
Modbus TCP X-Driver
Not every possible format of data is included in the Modbus IP X Driver.
The following data formats are supported in version ModbusTCPIP_2ndGen200018.xdr:
- Unsigned Integer 16 bit
- Signed Integer 16 bit
- Reverse Floating Point 32 bit
- Floating point 32 bit
- Long Integer Unsigned 32 bit
- Long Integer Unsigned Swapped 32 bit
If the products used have a different data format then this would require a new development of the X Driver, please see Will Continuum communicate with a third party system? for contact details.
Also ensure that the X Driver point type created (Numeric, Input, Output) is supported by the function code used. Check out the X Driver manual for the list of point types supported by each function code. For example Function code 3 can be used with Numerics and Outputs, but not Inputs.
