Introduction
TELEPERM M Process Control System
Introduction
■
Overview
The TELEPERM M process control system pro-
vides all functions required for process automa-
tion. It is highly suitable for the complete
automation of continuous or discontinuous
(batch) processes.
The TELEPERM M systems are divided into
functional units optimized for different task en-
countered with process automation:
• Automation systems
• Operator systems
• Bus systems.
Automation systems
The TELEPERM M automation system of type AS 488/TM based
on the SIMATIC M7-400 hardware platform is available with two
performance levels and four different design versions for pro-
gram-controlled processing of process signals.
The system software functions of the AS 488/TM are compatible
with the system software version G of the previous AS 235 sys-
tem. Existing application software of the AS 230 / AS 235 auto-
mation systems can be used further, application software of
AS 220 automation systems only following conversion.
The AS 488/TM can be operated on both the CS 275 and
PROFIBUS-TM system buses. As a result of its variable configu-
ration, it is equally suitable for TELEPERM M migration, for the
expansion of existing systems, or the design of new systems.
Application details:
• Replacement of existing AS 220 / AS 230 / AS 235 automation
systems during migration by replacement of the existing basic
rack by a preassembled rack with the AS 488/TM system
• Expansion of existing systems on the CS 275 system bus
• Expansion of existing systems by PROFIBUS-TM system com-
ponents using the CS-L2 bridge
• New systems
In the case of new systems, the PROFIBUS-TM based on the
standardized PROFIBUS is preferably used as the system bus.
Using TELEPERM M-specific communication, automation sys-
tems connected on the PROFIBUS-TM can communicate with
one another and also with TELEPERM M components on the
CS 275 system bus coupled via the CS-L2 bridge.
A wide range of TELEPERM M input/output modules is available
for the AS 488/TM, some of which have their own processing
functions or are configurable specific to the application. Via one
or two PROFIBUS-DP interfaces it is additionally possible to con-
nect SIMATIC ET 200B, ET 200M, ET 200S, ET 200X and
ET 200U distributed I/O systems with a comprehensive selection
of I/O modules. Within this range, the I/O modules of the
ET 200M distributed I/O system which have been specially tai-
lored to process engineering are particularly recommendable.
A large number of devices possessing a DP interface can be ad-
ditionally operated on the PROFIBUS-DP of the AS 488/TM. For
example, DP interfaces integrated in the CPU modules of the
SIMATIC S7-300 permit a simple slave connection to the
AS 488/TM. Gateway modules on the PROFIBUS-DP
(DP/PA link, DP/AS-i link, DP/DP coupler) additionally permit
access to the PROFIBUS-PA and AS-Interface fieldbuses and to
the I/O buses of SIMATIC PCS 7, S7-300, S7-400 or systems
from other vendors.
Operator systems
The bus-based PCS7/TM-OS operator system is used for pro-
cess communication. The PCS7/TM-OS is suitable as a
HMI component for the AS 488/TM and the TELEPERM M
AS 220 S / AS 220 H, AS 215, AS 230 / AS 230 K, AS 235 /
AS 235 K / AS 235 H and AS 388/TM automation systems which
are no longer actively marketed. It communicates with the
subordinate TELEPERM M automation systems and with
SIMATIC S5-155U via one of the CS 275 or PROFIBUS-TM field
buses.
The variable configuration of the PCS7/TM-OS operator system
from a single-user to multi-user system with single-client or multi-
client functionality covers the complete bandwidth of the appli-
cation spectrum from low-end to high-end performance.
The wide variety of operator-accessible automation systems to-
gether with the variability for communication and expansion
mean that the PCS7/TM-OS is well qualified as a replacement for
older TELEPERM M operator systems, for system extensions or
for new systems.
