In the following every relevant parameter of a Siemens S7 connection
is described:
n Local connection end point:
Here you may define how the connection is to be established.
Since the Siemens SIMATIC Manager can identify the communi-
cation options by means of the end points, some options are
already preset and may not be changed.
– Establish an active connection:
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.
– One-way:
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
n Block parameters
– Local ID:
The ID is the link to your PLC program. The ID must be iden-
tical to the ID of the call interface of the FB/SFB VIPA handling
block.
– [Default]:
As soon as you click at [Default], the ID is reset to system gen-
erated ID.
n Connection path:
In this part of the dialog window the connection path between the
local and the partner station may be set. Depending on the linking
of the modules the possible interfaces for communication are
listed in a selection field.
– [Address details]:
With this button a dialog window is opened, which shows
address information about the local and partner station. The
parameters may also be changed.
– TSAP:
With Siemens S7 connections a TSAP is automatically gener-
ated of the connection resource (one-way/two-way) and state
of place (rack/slot respectively system internal ID at PC sta-
tions).
– Connection resource:
The connection resource is part of the TSAP of the local sta-
tion respectively of the partner. Not every connection resource
may be used for every connection type. Depending on the
connection partner and the connection type the range of
values is limited respectively the connection resource is fix
specified.
