Manual VIPA System 300S SPEED7 Chapter 4 Deployment
HB140E - CP - RE_343-1EX71 - Rev. 09/46 4-31
For data transfer with Siemens S7 connections the FB/SFB VIPA handling
blocks are necessary; the deployment is described in the manual
"Operation list" of your CPU.
At Siemens S7 connections the communication connections are specified
by a connection ID for each communication partner.
A connection is specified by the
local and partner connection end point. A
link. At Siemens S7 connections the TSAPs must be congruent crosswise.
The following parameters define a connection end point:
Station A Station B
remote TSAP
→
Siemens

local TSAP

The following table shows the combination options with Siemens S7
connections with deployment of the FB/SFB VIPA handling blocks.
The handling blocks are more described in the manual "Operation list" of
the CPU.

In the following every relevant parameter of a Siemens S7 connection is
described:
Here you may define how the connection is to be established. Since the
Siemens SIMATIC manager can identify the communication options by
means of the end points, some options are already preset and may not be
changed.
An established connection is precondition for data transfer. By activating
the option
Establish an active connection the local station establishes the
connection.
Please regard not every station is able to establish a connection. Here the
job is to be made by the partner station.
If activated only one-way communication blocks like PUT and GET may be
used for communication in the user program. Here the partner station acts
as server, which neither may send active nor receive active
