Reserved Parameter value (PWE)
Depending on the data format, the length of the parameter value is between 1 to 4 bytes.
Data is saved in the Motorola format, i. e. first the high byte or high word, then the low byte
or low word.

A slave provides the response until the master creates a new job.
For responses containing parameter values, the slave always replies with the current value
(cyclic processing).
