2.3.12 Configuring Point-to-Point CPs
Introduction to Configuring Point-to-Point CPs (PtP CPs)
Configuring Central Racks
As with other modules, you drag communication processors from the Hardware
Catalog window and arrange them and assign parameters to them in the
configuration table (General Settings, Addresses and Basic Parameters).
You can start the optional software for setting the procedure parameters by means
of the Parameters interface in the Basic Parameters tab.
For PtP CPs in a SIMATIC 400 station, you have to configure PtP connections. The
following section describes the procedure briefly. You can find a more detailed
description in the manuals for the PtP CPs.
Configuring Connections for S7-400 PtP CPs
For the connection between an S7 CPU and a partner that is connected by means
of a point-to-point interface, the PtP CP represents the link.
You must configure connections between the S7-400 CPU and the PtP CP.
Proceed as follows:
1. In HW Config, configure the PtP CP and, if the connection partner is also a PtP
CP in an S7-400 station, configure the partner station also.
2. Start NetPro (from HW Config: menu command Options > Configure
Network).
3. If you have already created a PtP subnet while you were configuring the PtP
CP and you have networked the CP, continue with step 4;
otherwise, insert a PtP subnet and use it to network the CP.
4. Select the connection partner:
- The connection partner is a CP 34x (PtP CP in an S7-300 station), an S5
CP PtP, a printer, or a device from another manufacturer:
Configure an "Other Station" as connection partner. For the "Other
Station," configure a PtP interface and network this interface with the PtP
subnet that you created.
- The connection partner is a PtP CP for a SIMATIC 400 station:
You have already configured the connection partner in step 1 and so you
can continue with step 5.
5. Configuring PtP Connections
6. Load the configuration data and the connection data into the appropriate
stations.
