Please regard that the following software packages must be installed for
the project engineering:
•
Siemens SIMATIC Manager V. 5.1 and vipa_21x.gsd (is included).
•
Siemens SIMATIC NET
To enable the stations to communicate with each other you have to
configure the required (sub)nets in the Siemens SIMATIC Manager res.
NetPro following this approach:
•
Create one or more subnets of the wanted type in your project.
•
Adjust the properties of the subnets.
•
Connect your participants logically to the subnet.
•
Establish communication connections between the single stations.
You may administrate several subnets in one project. Every station has to
be created once. A station may be assigned to several subnets by
assigning the CPs accordingly.
In the following typical project variants for networks are listed:
The simplest case is a plant with stations that have to be connected via
one subnet of the type Industrial Ethernet.
For this you create an object "Ethernet". Stations that are created in the
same project refer to this object when they are configured as net knots.
They may then be selected directly. Foreign devices are listed in this
subnet as "Other station" during project engineering.
Due to different tasks of the stations or due to the expansion of your plant it
may be necessary to create several nets. Here you may create several
subnets in one project and configure the stations easily for communication.
At complex linked plants it is sensible to administrate plant parts in several
part projects. Here it may be necessary to create project exceeding
connections. For this the Siemens SIMATIC Manager starting with V5.2
provides the multi project function. This function allows you to split projects
and join them again. A more detailed description is to be found in the
manual of the Siemens SIMATIC Manager.
These are connections that long into another subnet due to the complexity
of the plant. The subnets are connected via a router. By setting a router
address during the hardware configuration of your CP you may instruct the
CP to include the according subnet via this router for communication.
