PROFINET/Industrial Ethernet
SIMATIC PCS 7 process control systems
AS 410 modular systems
A particular characteristic of the modular S7-400 systems is the
flexible and scalable availability of various components.
For a SIMATIC PCS 7 AS Single Station of the AS 410 type, you
have the option of specifically increasing the availability by
implementing a redundant configuration of the power supply or
the Industrial Ethernet communications module, and combining
these measures.
Even the AS Redundancy Station of the AS 410 type with its
redundant CPUs offers significantly higher availability. It oper-
ates according to the 1oo2 principle, in which a switch is made
from the active subsystem to the standby system in the event of
a fault. Starting from here, you can double the power supply or
the Industrial Ethernet communications module for each sub-
system, and combine these measures.
CPU 410-5H Process Automation
CPU 410-5H Process Automation
The CPU 410-5H Process Automation is the heart of standard
automation systems, as well as the fault-tolerant and safety-
related AS 410 automation systems. Expansion cards for
100 PO, 500 PO, 1 000 PO, 1 600 PO and
2 000 PO (PO 2k+)
can be used to increase their performance in a user-defined
manner to up to approximately 2 600 PO.
As shown in the figure, CPU 410-5H Process Automation is
equipped with a PROFINET IO interface (2-port switch) for up to
250 I/O devices and a PROFIBUS DP interface for up to
96 PROFIBUS DP slaves. Two integrated slots allow the syn-
chronization of two redundant subsystems via sync modules
and sync cables (FOC).
CPU 410-5H Process Automation supports NTP as well as S7
time synchronization.
Other features include:
•
Integrated 48 MB load memory and 16 MB RAM each for
program and data
•
Cycle time up to 10 ms/9 process tasks
•
Total number of I/Os (on PROFIBUS DP and PROFINET IO)
approx. 7 500 (16 KB each for inputs and outputs)
•
Additional protection of the circuit board with coating
(conformal coating)
•
High-precision time stamping
•
Recessed RESET button
•
Preset hardware parameters (PCS 7 skinning)
For detailed information about CPU 410-5H Process Automa-
tion, see "Technical specifications".
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 field-
bus (PROFIBUS PA or FOUNDATION Fieldbus H1). For details
on this, see sections "PROFIBUS DP", "PROFIBUS PA" and
"FOUNDATION Fieldbus H1" in the "Communication" chapter.
PROFIBUS DP segments with distributed process I/O can be
operated on a PROFIBUS DP interface in the CPU and on
additive CP 443-5 Extended (conformal coating) PROFIBUS DP
interfaces. You can configure up to 4 individual or redundant
CP 443-5 Extended PROFIBUS DP interfaces (conformal
coating) for an automation system using the configurators for
SIMATIC PCS 7 automation systems in the Industry Mall as
well as in the catalog sections "Standard automation systems",
"Fault-tolerant automation systems" and "Safety-related auto-
mation systems".
You can additionally implement further PROFIBUS interfaces
using separately ordered CP 443-5 Extended PROFIBUS DP
interfaces (conformal coating). According to the manual, up to
10 CP 443-5 Extended interfaces (conformal coating) can be
operated in one automation system.
I/O connection via PROFINET IO
You can easily and efficiently connect AS 410 automation
systems to remote I/O stations via the PROFINET IO interface
integrated in the CPU 410-5H Process Automation, for example,
to remote ET
200M I/O stations (see also the "PROFINET" section
in the "Communication" chapter). PROFINET IO interfaces made
available by additive communication modules of the CP 443-1
type (conformal coating) cannot be used.
