PROFIBUS DP interface for IS1+
4 Ethernet Interface 9442 CPU
4.1 Ethernet Network Topology
The IS1 + 9442 CPU has two Ethernet ports (X2, P1, as well as X2, P2).
Using PROFIBUS protocol the port X2, P1 can be used only.
X2, P2 is not supported in this case.
4.2 IP Address setting
Two separate IP addresses for the Ethernet communication are available for the 9442 IS1 CPU:
IP-AS:
Not used with PROFIBUS
IP-SB:
Service Bus Functions: Web-Server, SW-Update
A change of IP addresses is blocked during active data exchange to the Automation System.
Caution!
IP-AS and IP-SB addresses of a CPU must be unique as all IP addresses of an Ethernet network.
The IP address information is stored in the socket backup memory as well. Configuration and address
information of an IS1+ field station are therefore preserved in case of exchange of CPUs.
4.3 IS1+ Detect
The ´IS1+ Detect´ tool can scan the Ethernet Network for connected IS1+ field stations with 9442 CPUs
and display the IP addresses of the found CPUs.
This applies also to stations which are outside of the IP-addressable address range of the network.
IP-SB addresses of found IS1+ 9442 CPUs can be changed if necessary and must be inside of the IP-
addressable address range of the network.
Thus the IS1+ CPUs are accessible via the integrated Web server. Diagnostic information can be displayed
here and further adjustments can be made.
