Automation Systems
Modular AS 410-5H and AS 410E systems
Safety-related automation systems
Individual configuration of AS bundles
Configuration of the safety-related automation systems as well
as the Article No.'s can be defined by selecting pre-configured
ordering units.
Typical combinations for the respective system can be selected
using tables in the "Ordering data" section. These are divided
into:
•
AS Single Station AS 410F with one CPU
•
AS Redundancy Station AS 410FH with two redundant CPUs,
mounted on one common rack (UR2-H) or two separate racks
(UR2)
The complete range for selection is available using two corre-
spondingly structured online configurators in the Industry Mall:
•
SIMATIC PCS 7 AS 410 Single Station configurator
•
SIMATIC PCS 7 AS 410 Redundancy Station configurator
System expansion cards including an S7 F systems Runtime
license should be selected here for safety-related AS 410 F/FH
automation systems.
FO sync cables longer than 1 m must always be ordered sepa-
rately (2 cables required in each case).
The components suitable for engineering the safety-related
applications can be ordered in the section "Safety Integrated for
Process Automation":
•
S7 F Systems
F programming tool with F block library for programming
safety-related user programs on the engineering system
•
SIMATIC Safety Matrix
Convenient safety lifecycle tool for configuration, operation
and servicing
Subsequent increase in performance
If the performance limit defined by the ordered system expan-
sion card is reached during configuration, commissioning or
operation, a subsequent increase in performance is possible by
using an appropriate number of CPU 410 Expansion Packs
100 POs/500 POs. Hardware modifications are not necessary.
I/O connection via PROFIBUS DP
The distributed process I/O can be integrated into a
PROFIBUS DP segment either directly or via a lower-level
PROFIBUS PA fieldbus. Several PROFIBUS DP segments with
distributed process I/Os can be operated on an AS 410F/FH
automation system.
A PROFIBUS DP interface is already integrated in each
CPU 410-5H Process Automation. Using the online configurator
in the Industry Mall or in the Ordering data, up to four additional
PROFIBUS DP interfaces can be configured with additive
CP 443-5 PROFIBUS DP interfaces (conformal coating) for each
AS 410F as well as for each subsystem of the AS 410FH.
Connection of the process I/Os to two redundant PROFIBUS DP
lines of an FH system (AS Redundancy Station) is carried out as
described in the section "High availability automation systems".
The FOUNDATION Fieldbus (FF) H1 and the FF devices are not
supported by Safety Integrated for Process Automation.
I/O connection via PROFINET IO
Safety-related AS 410F/FH automation systems can be con-
nected via PROFINET IO with remote I/O stations, for example,
ET 200M or ET 200SP remote I/O stations. Only the two
PROFINET interfaces (2-port switches) integrated in the CPU
can be used for this on the automation system. You can find
more information in the section "Safety Integrated for Process
Automation", "Introduction".
Communication over the plant bus
If the PROFINET interfaces integrated in the CPU of the safety-
related automation systems are not used for PROFINET IO, they
are then available for connection to the Industrial Ethernet plant
bus. Otherwise, the AS 410F and the two subsystems of the
AS 410FH can be connected to the plant bus via one CP 443-1
(conformal coating) communication module each.
The plant bus can be implemented in the form of a ring structure,
which can also be configured with redundant architecture if the
availability requirements are high. When there are two redundant
rings, it makes sense to configure two IE interface/communica-
tion modules per AS (AS 410F) or AS subsystem (AS 410FH)
and to distribute their connections over the two rings (4-way con-
nection). Double faults such as failure of the switch on ring 1 with
simultaneous interruption of the bus cable on ring 2 can thus be
tolerated.
Runtime licenses
Safety-related automation systems come furnished with the
SIMATIC PCS 7 AS Runtime license for 100 process objects
(PO) and the S7 F Systems RT license. The 100 POs of the
SIMATIC PCS 7 AS Runtime license can be expanded by addi-
tional Runtime licenses for 100, 1 000 or 10 000 POs. The pro-
cess objects of additional Runtime licenses can be added to
process objects which already exist. The number and type
(e.g. 100 or 1000) of additional Runtime licenses are irrelevant.
