Figure 6-15 Structure of the parameter index (IND)
● For indexed parameters, select the index of the parameter by transferring the appropriate
value between 0 and 254 to the subindex within a job.
● The page index is used to switch over the parameter numbers. Use this byte to add an
offset to the parameter number that is transferred in the 1st word of the parameter
channel (PKE).
Page index: Offset of parameter number
The parameter numbers are assigned to several parameter ranges. The following table
shows which value you must transfer to the page index to achieve a particular parameter
number.
