9.2 Hardware and Software Requirements for
AS-AS Remote Link
Certain hardware and software requirements have to be fulfilled so that a local
automation system can establish a remote connection to a remote automation
system. These requirements are described below.
Hardware Requirements
In order to transfer process data from a local to a remote automation system you
do not require any additional hardware to that also needed to access the respective
automation system from the programming device / personal computer.
To establish and disconnect the remote connection, the STEP 7 user program of
the local CPU calls a function block. This FB can be executed on an S7-300/400
CPU or also C7 CPU. The function block assumes that the S7 Basic
communication is implemented on the CPU. The remote CPU must also support
S7 Basic communication.
A TS Adapter I with a version equal to or greater than V5.1 or a TS Adapter II must
be used.
Software Requirements
The TeleService product includes FB 47 "AS_DIAL" function block that is included
in the library of STEP 7 when the TeleService S7 library is installed. In order to
establish and disconnect a remote connection from a local automation system to a
remote automation system the "AS_DIAL" function block must be called up in your
STEP 7 user program of the local CPU.
