5.1.4 Application block (FO)
A maximum of 48 applications/tightening applications (A) can be programmed in one communication unit
(KE). Of them, up to 8 tightening applications can be simultaneously controlled via the eight available
application blocks (FO1 ... FO8), if they are not accessing the tightening channels (Ch) at the same time.
1to 40 tightening positions can be coordinated within a tightening application.
For application control, the tightening controller (PLC) applies the control signals of application blocks
FO 1 ... FO 8 (see figure 5–1). These are accessible via the KE PLC signals along with other signals.

5.1.5 PLC signals
A PLC assignment table, which lists the assignment of the PLC signals to the inputs and outputs, can be
created using the BS350 operating system:
•SE/CS: File  New  SE/CS PLC assignment table
•KE: File  New  KE PLC assignment table
There must be an existing tightening controller configuration before the PLC assignment table can be
configured (SE, CS, KE). After the PLC assignment table has been opened (File  New  PLC
assignment table SE/CS or File  New  PLC assignment table KE) , a dialog appears asking for
the configuration to be used. The configuration to be used can either be obtained offline from a
configuration file (*.scg with SE/CS or *.kcg with KE) or online from the tightening controller.
As of version V2.700 of the Rexroth Tightening System 350, the entries in the PLC assignment table can
be sorted in alphabetically ascending/descending order.
Particularities with the KE: The KE controller interface is laid out so that it can be configured using an
assignment table. The configuration of the control interface is made by selecting and lining up individual
signals. Up to eight applications can be processed simultaneously. The are controlled using a signal unit
(application block). In addition to the application-related signals, the individual tightening channel signals
of the controller interface are shown.
