Introduction

TELEPERM M Process Control System

■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.
