6.1
Tightening cell
A tightening cell is designated as the in-
stalled hardware for at least one tightening
channel and at least one data interface for
communication with the operating or evalua-
tion program or the superior controller. This
includes the corresponding tightening pro-
grams and tightening applications.
A tightening channel is controlled by a
SEH302 tightening control unit. The KE300
and SEH302 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, please see:
– 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).
