TeleService V6.1 Service Software for SIMATIC S7 and C7
8-2 A5E00921336-01
8.2 Requirements for Establishing a Connection
Certain hardware and software requirements have to be fulfilled if it has to be
possible for a remote plant to establish a remote connection to a programming
device / personal computer. These requirements are described below.
Hardware Requirements:
In order to establish a remote connection you do not require any additional
hardware to that also needed to access the remote plant from the programming
device / personal computer.
In order to establish a connection your application program calls up a function
block. This FB can only be executed on an S7-300 or S7-400 CPU on which the
S7 basic communication is implemented.
The TS Adapter I with version 5.0 or a later version or a TS Adapter II must be
used.
Software Requirements at the Plant End:
The scope of delivery of TeleService includes the FB 46 "PG_DIAL" function block
which is included in the library of STEP 7 when the TeleService S7 library is
installed. If a remote plant is to establish a remote connection to a programming
device / personal computer, the application program of the plant has to call up the
FB 46 "PG_DIAL" function block.
Software Requirements on the Programming Device / Personal Computer
You require a software component of the programming device / personal computer
which together with TeleService waits for the call of a remote plant, recognizes it
and informs your application program. In the first stage this functionality is
implemented by the product PRODAVE MPI.
Your application program interfaces with the interface provided by PRODAVE MPI.
PRODAVE MPI allows you not only to accept calls, but also to establish remote
connections. For detailed information on its functionality as well as on the interface
description please refer to the product description of PRODAVE MPI V5.0 (or
later).
