Communications Systems
We offer the following communications facilities for the S5-115F programmable controller via the
SINEC L1 LAN:
•
Reliable communications among several S5-115F controllers (max. 30) (single-channel SINEC L1
LAN)
•
Reliable and fault-tolerant communications among several S5-115F controllers (max. 15)
(double-channel SINEC L1 LAN)
•
Communications with an S5 controller of the U range for operator-process communication
and visualization (single-channel SINEC L1 LAN) (Reaction-free, i.e. no adverse effects possible
on the safety-oriented parts of the system.)
•
Communications with two S5 controllers of the U range for operator-process communication
and visualization (double-channel SINEC L1 LAN) (Reaction-free, i.e. no adverse effects
possible on the safety-oriented parts of the system.)
A failsafe point-to-point connection between two S5-115F PLCs can also be established using the
CP 523 ( Catalog ST57).
Note
Since the SINEC L1 link has been proven to be reaction-free, the area in which
acceptance tests are required ends at the CPU 942F.
The user program must constitute a safety filter for incoming data. Higher-level
systems then have no influence on the reliable functioning of the S5-115F. This
considerably simplifies individual system acceptance tests.
