Figure F.4 Parameter Read Full Message Structure (Continued)
Message Operation
Parameter Read Full retrieves the attributes of the specified parameter.
The attributes for each parameter include the data, minimum and
maximum values, and the parameter text. The response message returns
this information.
If an error has occurred in reading any of the values, word 3 contains the
status word.
The parameter text is returned with each data word containing two
ASCII characters per word. The first and second characters are in
opposite order.
Example
In this example, a Parameter Read Full was performed through block
transfer on a 1336 PLUS drive. “PLC request” shows the header
message for the request. The data is returned in the response data file,
starting with word 3, for parameter 20. Word 3 shows the present value
in drive units. Word 4 through word 8 provide scaling information, used
to convert drive units to engineering units for the Human Interface
Module (HIM). Word 9 through word 16 provide the parameter name.
