Gateway GT104CS: AS-AS bus communication
TELEPERM M - PCS 7
■ Overview
SIMATIC PCS 7 plant sections on the Industrial Ethernet plant
bus can be linked perfectly with existing TELEPERM M plant
sections on the CS 275 plant bus by a combination of the
PCS7/TM-OS operator system with double-channel functionality
and GT104CS gateway. This combination enables the communication
load to be distributed evenly over the plant bus. While the
PCS7/TM-OS operator system with its double-channel functionality
takes over the AS-OS communication with the automation
systems on both CS 275 plant buses and Industrial Ethernet, as
well as the clock synchronization for the TELEPERM M plant section,
the inter-plant bus AS-AS communication is processed via
the GT104CS gateway.
The gateway behaves like a virtual automation system.
In connection with the GT104CS gateway, the automation systems
AS 488/TM, AS 235, AS 230 and AS 220 can be used on
the TELEPERM M side. The gateway has a bus and node address
on the TELEPERM M CS 275 plant bus, via which the cyclic
data can be exchanged with as many as 32 automation systems
on the SIMATIC PCS 7 Industrial Ethernet plant bus (TCP/IP
protocol). The communication is configured in the participating
function blocks of the TELEPERM M and SIMATIC PCS 7 automation
systems and can also be performed online. Once the
connection is set up, the gateway couples the configured transmission
and reception blocks.

■ Configuration
At the GT104CS gateway, the bus and bus node address are to
be set on the plant bus CS 275 by means of DIP switches. For
communication with the SIMATIC PCS 7 automation system, the
gateway requires only a few parameters (IP address). The connection
between the SIMATIC PCS 7 automation systems and
the gateway is configured using the SIMATIC Manager.
The necessary configuration work for this is minimal. For the
SIMATIC PCS 7 automation systems, function blocks for the
TELEPERM M standard functions AKS, BKS, AKE and BKE are
also supplied, as well as a central communications block
TM_LINK.
By means of the TM_LINK communications block and the
GT104CS gateway, the AKS, BKS, AKE and BKE blocks of the
SIMATIC PCS 7 automation systems communicate with the AKS,
BKS, AKE and BKE blocks in the TELEPERM M automation systems,
which are assigned by addressing. The function block
TM_LINK uses the S7 system functions USEND and URECV internally
for communication with the gateway.
