Migration of existing telecontrol systems
Units with Modbus communication
The Modbus is widely used in automation plants due to its
straightforwardness and openness. The Modbus telecontrol
protocol can be used to implement both serial and TCP/IP com-
munication links between a control center in SIMATIC PCS 7
and RTUs with a corresponding Modbus interface.
straightforwardness and openness. The Modbus telecontrol
protocol can be used to implement both serial and TCP/IP com-
munication links between a control center in SIMATIC PCS 7
and RTUs with a corresponding Modbus interface.
In this manner, existing units with a Modbus infrastructure
can be integrated at low cost into the SIMATIC PCS 7 process
control system. The RTUs of these units can be SIMATIC S7
controllers (SIMATIC ET 200S with integral CPU, SIMATIC
S7-300/S7-300F and SIMATIC S7-400/S7-400F) as well as
third-party RTUs. Whereas RTUs with Modbus TCP/IP interface
can be integrated directly, serial third-party RTUs require spe-
cific interface converters for telecontrol communication.

Engineering data of third-party RTUs can be imported in CSV
format into the PCS 7 TeleControl engineering (DBA). The sta-
tus of the RTUs and the transmission paths is evaluated by the
"Diagnostics Modbus RTU" block and displayed in the control
center.

SINAUT ST1 stations based on SIMATIC S5
During the migration of existing systems, it is possible to inte-
grate outstations based on SIMATIC S5 into the SIMATIC PCS 7
process control system using SIMATIC PCS 7 TeleControl. In
the process, the ST1 telecontrol protocol is converted into the
ST7 protocol in the central TIM communication module.

Third-party stations
In addition to the Modbus telecontrol protocol, the DNP3
(serial and TCP/IP), IEC 870-5-101 (serial) and IEC 870-5-104
(TCP/IP) telecontrol protocols basically also support the con-
trol center linking of third-party RTUs when migrating existing
systems. The implementation depends on whether the third-
party RTU masters the corresponding protocol and whether
the interface converters are available if necessary.
