The NTx power supply (NT1 to NT4) supplies the entire basic device with
current.
The CL550 is programmed with WinSPS, WinDP or the CMD software by
Phoenix Contact. The classic PLC languages, like ladder diagram, instruc-
tions list, function diagram, sequential function chart, and structured text as
well as, alternatively, the high-level language ANSI "C" are available as pro-
gramming languages.
For communication with WinSPS, WinDP and other programs, the TCP/IP
standard protocol with the BUEP (Bosch transmission protocol) command
language is used.
.
For further information regarding the CL550 and the operation of the
decentralized peripherals via PROFIBUS-DP, please refer to the
WinSPS and WinDP online help.
A commonly used LAN technology is the Ethernet. It is defined in the IEEE
802.3 specification. All computers connected to the Ethernet network sys-
tem share the same cable and the highest possible bandwidth of 10 Mbit/s or
100 Mbit/s.
Ethernet and Internet protocols are the basis for communication. On an
Ethernet basis, the UDP/IP standard protocol is used in order to send Bosch
BUEP commands. The thus created protocol is called BUEP-E. To do so, the
ZS550 is provided with two Ethernet interfaces. The interfaces can be oper-
ated with up to 100 Mbit/s. One interface is located on the frontside, the other
is located on the back and serves for communication on the system bus.
Communication via TCP/IP Ethernet is used with the following two applica-
tions:
D Communication PLC – HMI (Human Machine Interface):
Each CL550 central processing unit communicates with the correspon-
ding HMI via the front Ethernet interface.
D Communication PLC – PLC:
The central processing units communicate with each other on an
Ethernet basis via the CON550 module.
