5.2.21 Value
The value field contains the parameter value of the request. When the response is negative, the field contains a corresponding error code. If the values consist
of an odd number of bytes, a zero byte is appended in order to maintain the word structure of the messages.
For a positive partial response, the parameter value field contains the following attributes:
Format = (Data Type or Byte, Word, Double Word)
Number of values = actual number of values
Value = Parameter value
For a negative partial response, the parameter value field contains the following:
Format = error (44H)
Number of values = 1
Value = error value = error number
