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 telegrams.

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
