SIMATIC PCS 7 process control system

Industrial Ethernet switches
■ ESM (electrical) and OSM (optical) with 2 ring ports each
for transmission rates up to 100 Mbit/s and, depending on
the type, up to 8 ports (RJ45, ITP or BFOC) for data terminals
or network segments
■ SCALANCE X414-3E with
- 2-Gigabit Ethernet ports for Gigabit rings: electrical or
optical 1)
- Up to 20 electrical 100-Mbit/s ports (12 integrated and 8
per extender) for connecting data terminals or network
segments
- 2 optical ports 1) for 100-Mbit/s rings
- Up to 10 optical 100-Mbit/s ports 1) , of which 8 per
extender for connecting data terminals or network segments
■ SCALANCE X208 with 8 ports for transmission rates up to
100 Mbit/s, suitable for electrical Industrial Ethernet structures
with linear, star or ring topology
■ SCALANCE X204-2 with 2 optical ports and 4 electrical
ports for transmission rates up to 100 Mbit/s, suitable for
optical Industrial Ethernet structures with linear or ring
format
1) In conjunction with media module
As a result of their interference resistance and high availability,
optical rings are preferably used for the plant bus and
OS LAN (terminal bus). Both the OSM/ESM switches and the
SCALANCE X414-3E can be used as the redundancy manager
in a ring. The redundancy manager recognizes the failure of a
transmission link or a switch in the ring and activates the
standby link within 0.3 seconds.
The standby function of the OSM/ESM switches enable the
plant bus to be designed as a redundant double ring if necessary.
This configuration also tolerates double faults such as an
OSM/ESM failure on ring 1 and simultaneous opening-up of
the bus cable of ring 2. The switch operated at standby on ring
2 recognizes failure of the redundant partner via a connection
cable, and activates the standby bus.

Industrial Wireless LAN (IWLAN)
SIMATIC PCS 7 offers the possibility for integrating remote
clients into the OS LAN via Industrial Wireless LAN:
■ OS clients based on SIMATIC PCS 7 basic devices
ES/OS/BATCH/IT communicate via two SCALANCE W788-
1PRO units. One is operated as an access point on the
OS LAN, the other as an Industrial Ethernet client module
on the remote client on site.
■ Remote clients based on a mobile computer use a CP 7515
communications processor in the CardBus slot for communication
with the access point.
From the remote client, the user can access an engineering
station per remote desktop or PC Anywhere.
All components used are very rugged, apply state-of-the-art
authentication and encryption procedures, and guarantee
high reliability of the radio channel.
highlights
Industrial Ethernet
