6.4.1.3 Exchanged data
The following data can be exchanged via the interface module:
• Control signals from/to the partner controller
• ID-codes for single channels (control unit/communication unit) and for tightening applications
(communication unit)
• Tightening results from single-channel tightenings (control unit/communication unit), tightening
results from tightening applications (communication unit).
• IL data for data exchange with the integrated logic via the ControlFieldbus function block.
A description of the control signals and their applications can be found in chapter 5, Control signals, from
page 121.
Tightening results are output for each tightening process. This is why a clear identification of the
tightening results is necessary, to be able to e. g. assign archived tightening results at a later point. The
Tightening System 350 allows the identification of each tightening result record with an ID code provided
by the partner controller.

Data exchange via the interface module can only be implemented if the data input/output field has been
configured and at least one control signal has been set.
