4.3 Installation
Communication is normally based on the plant bus on the ISO protocol.
Note
Use TCP/IP on the plant bus under the following conditions:
● Joint (combined) terminal and plant bus for smaller plants without an OS server
● Routing via subnets required
● Using an automation system with integrated Ethernet interface
● Using NTP (Network Time Protocol) for time synchronization
● Monitoring network components on the plant bus for asset management
● Operating gateways on the plant bus (external connection of an AS)
Use the ISO protocol on the plant bus under the following conditions:
● Configuring "S7 connection fault-tolerant" for H systems (concerns CPU firmware less than
V5)
● Time synchronization based on the SIMATIC procedure
Using CP16x3/CP16x8
Using a CP16x3/CP16x8 in the engineering station or OS server has the following benefits:
● More than eight AS can be connected.
● High availability AS–OS connections with automatic switching of the communication can
be configured (also possible with a network card for CPUs with firmware V6 or higher).
● The "OS simulation" function can also be used for a redundant automation system.
● The CP MAC address can have parameters assigned to it or be modified.
Note
If a BCE (Basic Communication Ethernet) module is being used for communication instead
of the CP16x3/CP16x8, parameters cannot be assigned to the MAC address. In the event
of a fault (e.g. defective module) this may mean that the connections have to be
reconfigured by the new MAC address of the replacement module and the project
documentation has to be changed.
The following two TCP/UP protocols can be operated in parallel in the CP16x3/CP16x8:
● Windows communication (via the NDIS adapter)
● Communication via the "S7 online" access point (can be configured in NetPro/HW config)
Note
Different TCP/IP addresses have to be set in both TCP/IP protocols of the CP16x3/CP16x8
for unique identification purposes.
This applies in particular from version PCS 7 V7.1. From this version the NDIS adapter for
CP16x3/CP16x8 is installed automatically through the PCS 7 setup and it cannot then be
deactivated.
