7 Data Services Tightening Technology | Bosch Rexroth AG 131/3167.3 3964R communication7.3.4.3 Results transfer settingsResultsIn the Results section, you can set which results should be output 1) . If Out has been set, then resultsoutput via the 3964 protocol is inactive, i.e. no more results data will be written in the data elements andtransferred. The interface is, however, still activated for ID code transmission to the CS351 Compact System.Result valuesHere you can set whether just the actual values from the monitoring functions should be transferred, or ifthe set values should also be transferred 2) .NoteThe set and actual values are separated from each other in the data element and are written at the end ofthe section. If no set values are output, then less data elements have to be transferred; the transfer time,and thus the time needed for a tightening process, is shorter.Assignment of the result values to the individual data elements in the PLC is described on page 132.Number formatThe data elements on the PLC can basically be written using two different number formats 2)) :– Binary numbers– ASCII charactersAlthough the binary numbers provide a more compact display, they are more difficult to use for furtherprocessing (you might need to convert them into ASCII characters), while results output with ASCII charactersneeds more storage space but offers simpler processing.The number format of the measurement values when displaying the results as binary numbers is describedin Table 7–25 on page 134. Number “–1” represents an invalid value for the actual result valuesfor torque, angle, and gradient 3) . This is always the case if the controller has not listed a value (e.g. if notarget or monitoring function has been selected for “angle”, then the set and actual angle values as wellas the torque threshold are missing. These values will then be displayed as “–1”).The display and number of figures before and after the decimal point for results output in ASCII format isdescribed in more detail in Table 7–24.Result values that are not available (see above) are filled in with spaces “ ” (20 hex).Format assignment: Format 2A fixed format is defined if Format 2 has been selected. It contains set and actual value output in ASCIIformat with specific formatting (see page 132). If Format 2 has been selected, the settings for numberformat and result values are fixed and cannot be changed.1) This setting does not influence the results output via other data services.2) This is only possible if Format 1 has been selected in the window on the right (see Figure 7–33).3) The result values are absolute values, i.e. always > 0.System 350 | 3 608 878 040/05.2008
