System Introduction

1070 072 262-101 (01.09) GB
The I/Os are operated via a fieldbus at the decentralized peripherals.
.
INTERBUS-S-I/O and PROFIBUS-I/O must not cross each other at the
ZS550-DP-IBS. The INTERBUS-S in- and outputs are each addressable
from 0 to 1023 (can be set via CMD software, but with a maximum of 512
Byte in-/outputs only). The PROFIBUS-DP in- and outputs should be
addressed from I/O 2048 to I/O 8091 (can be set via Win-DP).
For communication between several central processing units, the additional
module CON 550, a switch on the Ethernet, is used.
Each module is provided with an unambiguously assigned slot ID in the rack.
Together with the rack ID which can be given individually to each rack, this
exactly identifies the ZS550 in the system or network.
.
During run-up, it is checked if an IP address has been assigned to the
central processing units. If this is not the case, the module stops with
an error message and waits for a response from the configuration tool.
Only when all modules have run up correctly, the entire system will be
enabled and the floating contact of the supply unit will be closed.
