Overview

Information

NOTE:
The S7 Communication Layer is a prerequisite for Simatic S7. In order to install the S7 Communication Layer, the Windows username should not have a space character in it. If it has a space character and the Installer shows an error message, you must install the S7 Communication Layer manually by navigating to the following location, …\InstallFiles\EM\Simatic_S7\Prerequisites.

The optimized block access for the automation station address area is not supported. The automation station has to be configured in compatibility mode for classic S7 block communication. This may lead to additional configuration effort. This configuration is valid till Desigo CC V4.0. From Desigo CC V4.x onwards, S7Plus driver caters to the communication with S7-1200 and S7-1500 devices.

Licensing

In addition to the licenses for the base feature set, clients, and options, sufficient S7 device connection and data point licenses have to be activated to run the system.

S7 Connection Licenses

Each connected S7 requires a S7 connection license (sbt_gms_add_S7_connections) . When installing the Simatic S7 extension module, eight S7 connection licenses are released to be used in the entire system. To connect more than eight S7 to the management platform, additional license packages (56 S7 connections) per Server or FEP are required.

Data Point Licenses

Any imported S7 tag requires 1 SCADA data point license. (See Supported S7 Data Type for an overview over the supported data types) (sbt_gms_add_scada_tag).

Standard Configuration

The standard configuration allows up to 64 S7 connections (8 pre-installed + 56 per S7 connection license) to the management station server. For larger configurations or other purposes (for example, load balancing, campus infrastructure) multiple FEP's can be added. Per FEP up to 56 additional S7 connections can be configured. In any case the standard network adapter can be used. The S7 communication link can be either the PNIO interface or an Ethernet CP interface (for example, CP-343).

Standard Configuration

 

Named Connection Configuration

In rare cases, such as fault tolerant configurations (Simatic S7-400 H) named connections have to be engineered. The named connection configuration allows up to 64 S7 connections (8 pre-installed + 56 per S7 connection license) to the management station server. For larger configurations or other reasons (for example, load balancing, campus infrastructure) multiple FEP's can be added. Per FEP up to 56 additional S7 connections can be configured. In addition, for each of the FEP's or Servers a SIMATIC NET REDCONNECT Software and a specific Ethernet network adapter (for example, CP1623) are needed.

Information

NOTE:
All named connection types are supported based on SIMATIC NET standard installation.
