Redundant plant bus
The Operator Systems (single stations or servers) communicate
with the automation systems via the Industrial Ethernet plant bus.
The following special points must be observed for redundant
configurations:
•
BCE communication with the 10/100/1000 Mbps Ethernet
card is generally sufficient even for redundant operator
stations. This allows the connection of up to 8 automation
systems per server pair (AS single stations only, not
AS redundancy stations). The BCE license is included for the
BCE versions of the SIMATIC PCS 7 Industrial Workstation. It
is also valid for an additional desktop adapter network
adapter.
•
Industrial Ethernet communication via CP 1623 (pre-installed
in the IE version of the SIMATIC PCS 7 Industrial Workstation)
or CP 1628 (with extra security functions) is required in the
following cases:
- The number of automation systems per OS is larger than 8.
- Redundant automation systems (AS redundancy stations)
are used.
•
The IE versions of the SIMATIC PCS 7 Industrial Workstation
are equipped with a CP 1623 and SIMATIC NET HARDNET-IE
S7 communication software, licensed for up to four CP 1623/
CP 1628 (4x license). If lower-level AS redundancy stations
are to be connected, however, SIMATIC NET HARDNET-IE
S7-REDCONNECT is required. The SIMATIC NET product
HARDNET-IE S7REDCONNECT PowerPack (license for
4 units) can be used to upgrade features.
•
If an operator station with BCE communication is to be
upgraded for operation with AS redundancy stations, a
CP 1623 or CP 1628 communication module is required in
addition to the SIMATIC NET HARDNET-IE S7-REDCONNECT
(4x license).
•
If the plant bus is to be designed as a redundant dual ring, you
require two interface modules (2 x Ethernet network adapters
10/100/1000 Mbps or 2 x CP 1623/CP 1628) per OS single
station or OS server.
The communication software for CP 1623 or CP 1628 is always
supplied with the SIMATIC PCS 7 software and installed in line
with the operating system.
In order to activate this communication software, you may need
additional licenses for the
•
SIMATIC NET HARDNET-IE S7,
•
SIMATIC NET HARDNET-IE S7-REDCONNECT or
•
SIMATIC NET HARDNET-IE S7 REDCONNECT PowerPack
communication products.
