6.1 Tightening cell
A tightening cell is defined as the installed
hardware for at least one tightening channel
and at least one data interface for communi-
cation with the operating or evaluation pro-
gram or the superior controller. This includes
the corresponding tightening programs and
tightening applications.
A tightening channel is controlled by an
SE312 tightening controller. The KE310 or
KE312 and SE312 communicate with each
other via an internal bus system.
Up to 48 tightening programs can be stored
in a tightening controller. Only 1 tightening
program can be started at a time.
6.2 Control signals
The tightening cell communicates with the
superior controller via control signals. A PLC
assignment table determines which control
signals are assigned to the inputs/outputs.
The inputs/outputs are assigned in the
BS300 operating program.
For more information, refer to:
– the online guide in the operating program
(programming the assignment table),
– the system documentation, chapter 5
"Control signals" (3 609 929 918) (signal
description, sequence examples, and
chronological sequences).
