Communication via Ethernet CPs in S7 Stations

1.7.4Network/Project Variant: One Subnet – More Than One (Sub)Project

Configuration of the System

In complex networked systems, during configuration it is sometimes more efficient to manage plant sections in different (sub) projects.

The situation can arise that communication takes place over an interproject subnet

and that interproject connections must then also be created. Example:

System section “Production 1”

System section “Production 2”

S7 400/1

S7 – 400/2

Ethernet (1)

 

S7 – 300/2

S7 – 300/3

S7 300/1

Organization in a Multiproject

User-friendly and consistent configuration of such communication is supported in STEP 7 as of Version V5.2 with the multiproject.

The functions for multiprojects in STEP 7 allow the following:

SSeveral projects can be managed in one multiproject and edited separately

SProjects can be branched and merged

Two different strategies can be distinguished in a multiproject:

SSeveral employees work at the same time on a multiproject in a networked environment. The projects of the multiproject are in different network folders. In this case, all connection partners are available for configuring connections.

SOne employee manages the multiproject centrally. This person creates the structures for projects (when necessary locally) and contracts individual projects out for external editing. The central configuration engineer then returns these projects to the multiproject and synchronizes the interproject data with system support and where necessary executes the required interproject functions.
