Introduction

Engineering

The PROGRAF AS+/NT configuring software which can be in- stalled on personal computers with the Windows NT or Windows 2000 operating system is predestined for the engi- neering of TELEPERM M automation systems. An engineering PC with PROGRAF AS+/NT can be connected to one of the two TELEPERM M system buses using a bus-specific interface mod- ule. It can then be used to configure an AS 488/TM or equally well to configure the 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.

PROGRAF AS+/NT can be used to graphically configure, test, optimize and document the application software of the TELEPERM M automation systems. The configurations of previ- ously installed automation systems can also be read in, recom- piled and subsequently processed further or documented in graphic form. Any PCS7/TM-OS-Single single-user system with RC license (Runtime+Configuration) is suitable for configuring PCS7/TM-OS operator systems. It is alternatively possible to use a server equipped with an RC license and additional operator terminal for OS configuring. The PCS7/TM-OCX (NORA) display blocks (if used) and the PCS7/TM coupling package dependent on the types of AS used must be installed on both configuring systems.

System bus

The system bus is the central communication component of ev- ery distributed process control system. Two different bus sys- tems are available for the TELEPERM M process control system, and can also be combined together within a plant:

•CS 275

•PROFIBUS-TM

The CS 275 bus system which has been proven in many auto- mation plants functions according to the token passing principle and can also have a redundant configuration. Several buses can be combined together using bus couplers such that bus net- works are produced corresponding to the plant structure. The bus system is provided with distributed control. The bus inter- face of each subsystem may take over the master function ac- cording to specific criteria.

The PROFIBUS-TM bus system also operates according to the token passing principle. It can be designed as an electrical or optical network. The two network structures can also be mixed together. A characteristic of the PROFIBUS-TM bus system is that it corresponds to the modern PROFIBUS communications standards according to EN 50170, but also uses the TELEPERM M dialog mechanisms of the CS 275 (AKS, BKS, MKS and PL/PS telegrams) at the application level (interface be- tween bus interface module and application).

PROFIBUS-TM is preferably used for new systems, or also for the expansion of existing systems. When extending systems, ex- isting components with CS 275 communication can be com- bined with new components using a CS-L2 bridge.

All automation systems and operator systems of the TELEPERM M process control system can be operated on the CS 275 system bus, but only the current AS 488/TM and PCS7/TM-OS systems as well as the AS 388/TM and OS 525 systems which are no longer actively marketed on the PROFIBUS-TM system bus.

TELEPERM M Process Control System

Migration strategy

The purpose of migration of the proven TELEPERM M process control system into the new, future-oriented generation of the SIMATIC PCS 7 system within the Siemens automation concept "Totally Integrated Automation" is to retain customer investments made in hardware and software and to provide them with a grad- ed, economical transition to newer, more productive technolo- gies with minimum technical and financial risks.

Migration is divided into the following steps:

•Innovation

-Migration of the TELEPERM M process control system by re- newal of components close to the process (automation sys- tems) and of system-internal communication with hardware of the SIMATIC M7 and PROFIBUS systems

-Expansion of the process I/Os for the innovative automation systems by integration of the ET 200M, ET 200S, ET 200U and ET 200X distributed I/Os and of the PROFIBUS-PA and AS-Interface fieldbuses via PROFIBUS-DP

-Linking of the existing CS 275 system bus to the new PROFIBUS-TM system bus via a CS-L2 bridge

-Integration of SIMATIC S5, SIMATIC S7 and SIMATIC PCS 7 systems with data coupling via PROFIBUS-AG/AG indepen- dent of the system bus

•Combination

Standardization of the HMI components of the TELEPERM M and SIMATIC PCS 7 systems on the basis of the SIMATIC PCS 7 operator station, as well as combination of partial TELEPERM M and SIMATIC PCS 7 systems with these com- mon HMI components

•Homogenization

Replacement of the TELEPERM M automation systems by SIMATIC PCS 7 automation systems with further use of existing TELEPERM M I/Os
