TELEPERM M
Brief description
Introduction
TELEPERM M
TELEPERM M process control system
The TELEPERM M process control system provides all functions 
required for process automation. It is highly suitable for the com-
plete automation of continuous and discontinuous (batch) pro-
cesses. 
The TELEPERM M systems are divided into function units opti-
mized for different tasks associated with process automation: 
• AS automation systems
• OS operator systems
• CS and PROFIBUS bus systems
AS automation systems
The various TELEPERM M automation systems have different 
designs, ranges of functions and performances. The AS 235, 
AS 235 H and AS 235 K automation systems described in this 
catalog are proven and reliable. They can be configured within 
wide limits and coupled to a wide range of subordinate systems. 
The AS 235 H additionally has a redundant central unit and thus 
satisfies particularly high availability demands. The AS 235 sys-
tems can communicate with one another and with higher-level 
systems via the TELEPERM M CS 275 plant bus.
A wide range of TELEPERM M input/output modules is available 
for connection of the process peripherals (sensors and final con-
trol elements) to the AS 235, AS 235 H and AS 235 K automation 
systems. Some modules have their own processing features or 
can be configured application-specific. 
The AS 388/TM and AS 488/TM automation systems (see Cata-
log PLT 112) use the SIMATIC M7-300 and M7-400 automation 
computers as the hardware platform and are compatible with the 
AS 235 system. They are appropriate for the extension of exist-
ing TELEPERM M systems or for the design of new systems. 
The AS 388/TM and AS 488/TM systems can be operated on the 
PROFIBUS-TM plant bus. PROFIBUS-TM is based on the stan-
dardized PROFIBUS. The AS 488/TM system can additionally be 
operated on the CS 275 plant bus.
ET 200M distributed I/O systems with a comprehensive range of 
I/O modules can be connected to the AS 388/TM and AS 488/TM 
systems via one or two PROFIBUS-DP interfaces.
OS operator systems
The bus-compatible OS 525 (Catalog PLT 122) and WinCC/TM-
OS (Catalog PLT 123) operator systems are used for process 
communication. They communicate with the subordinate 
TELEPERM M automation systems and with SIMATIC S5-155U 
via the CS 275 plant bus or PROFIBUS-TM.
The operator systems can have a configuration variable from a 
single-user system up to a multi-user system - where the OS 
basic unit communicates with several terminals via a terminal 
bus - and can thus cover the complete range from low-end to 
high-end applications.
The OS 525 
Local system permits the design of a local AS oper-
ating console with the complete range of OS 525 functions.
Engineering
The PROGRAF AS+ configuring software is used for the AS 235, 
AS 235 H, AS 235 K, AS 388/TM and AS 488/TM automation sys-
tems and offers a wide range of support for documentation and 
configuring by means of a graphic functional diagram editor and 
an integrated database, amongst others.
Any single-user system WinCC/TM-OS-Single with RC license 
(Runtime+Configuration) is suitable as the configuring system 
for WinCC/TM-OS, and an OS 525 single-user system/terminal 
with OS 525-BIPRO configuring software for OS 525.
Plant bus
The plant bus is the central communication component of every 
distributed process control system. Two different bus systems 
are available for the TELEPERM M process control system, and 
can also be combined together within a system:
• CS 275
• PROFIBUS-TM
The CS 275 plant bus which has been proven in many automa-
tion plants is predestined for communication between the 
AS 235, AS 235 H, AS 235 K and AS 488/TM automation sys-
tems and the OS 525 and WinCC/TM-OS operator systems. The 
CS 275 plant bus functions according to the token passing prin-
ciple and can also have a redundant configuration. Several 
buses can be combined together using bus couplers such that 
bus networks are produced corresponding to the plant struc-
ture. The bus system is provided with distributed control. The 
bus interface of each subsystem may take over the master func-
tion according to specific criteria.
The AS 388/TM and AS 488/TM automation systems and the 
OS 525 and WinCC/TM-OS operator systems can be connected 
to the PROFIBUS-TM plant bus. The PROFIBUS-TM is character-
ized in that it complies with the modern PROFIBUS communica-
tion standards to EN 50170 but also uses the TELEPERM M 
communication mechanisms of the CS 275 (AKS, BKS, MKS and 
PL/PS telegrams) at the user level (link between bus interface 
and application).
The PROFIBUS-TM plant bus also operates according to the 
token passing principle. It can be designed as an electrical or 
optical network. The two network instructions can also be mixed 
together. PROFIBUS-TM is preferably used for new systems or 
partial systems.
The CS 275 and PROFIBUS-TM buses can be connected 
together by a CS-L2 bridge, thus permitting linking of existing 
systems and new systems.
Note:
Information systems, computers from other manufacturers, per-
sonal computers and gateways can be connected to the CS 275 
plant bus. Personal computers with the Win TM software pack-
age can also be connected to PROFIBUS-TM.
