System Overview CL550
Slot coding
Power supply module
ZS550
CON550
The obligatory slot codes are as follows:
D Slot 1 + 2:
NTx power supply
D Slot 9:
LAN interface CON550
The other assignments can be chosen freely. The configurator's default set-
tings provide the following:
D CPU modules (ZS...) are set from left to right, next to the power supply.
D MAP modules are set from right to left.
.
The slot coding cannot be altered.
If the 9 slots of the mounting rack are not sufficient for the desired control
rack system, additional modules and peripheral modules can be plugged
into further mounting racks. The mounting racks can be connected together
in a network.
The NTx power supply supplies the mounting rack with current.
.
The external I/O modules need their own power supply. They do not
receive their current from the power supply unit.
A ZS550 module contains:
D PLC functionality (program flow)
D Busmaster PROFIBUS-DP (V1 functionality) for triggering the in- and
outputs
D TCP/IP communication:
D Backside: system buscommunication
D Frontside: external bus communication
D The ZS550-DP-IBS mounting rack has been additionally provided with:
InterBus-S interface
.
If the CL550 contains more than one ZS550, a CON550 module can be
added in order to enable the modules to communicate with each other
via the backside.
The CON 550 module is an Ethernet switch which connects the Ethernet in-
terfaces on the backside with each other. The address of the mounting rack
must be set with the rotary switch on the front. In addition to the 6 internal
Ethernet connections, the module is provided with 2 external connections. A
configuration program helps to assign and display the characteristics of the
module.
