Performance characteristics

￿The AS 235, AS 235 H and AS 235 K systems are programmable automation systems of the TELEPERM M process control system based on function blocks. They have a different design and availability, but the same range of functions. The AS 235 K sys- tem is fitted in a wall housing, the AS 235 and AS 235 H systems are fitted in cabinets. The AS 235 H automation system has a redundant central unit to satisfy particularly high demands placed on the availability.

The systems can either be used on their own with local operation and monitoring, or coupled in system networks with central oper- ation and monitoring.

System configuration

The automation systems consist of:

•A basic unit (AS 235, AS 235 H) or a basic system (AS 235 K)

•ES 100 K extension systems (wall housing) or extension units (for fitting in cabinets) as extension for configuring with input/ output modules.

Standard input/output devices enable local communication with the automation system during the configuring and commission- ing phases as well as during later operation. The following can be connected:

•54-cm (21-inch) process monitors

•Process operation keyboard and configuring keyboard, max. 2 of each for 2 independent operating consoles

•Max. 4 logging printers

•1 mini floppy disk unit for booting the system memory and for loading/saving the user memory.

Basic system/basic unit

The basic unit (AS 235, AS 235 H) or the basic system (AS 235 K) mainly contains

• the power supply modules,

I/O modules

There are the following groups of I/O modules:

•Signal modules

•Function modules

•Calculation modules

•Coupling modules.

Signal modules are required for input and output of the process signals, usually without further processing (exception: adapta- tion of characteristic with temperature measurements).

Function modules (closed-loop control modules) and calculation modules have additional performance features which are inde- pendent of the central unit of the automation system and which can be used to increase the total processing performance or the availability by transferring backup functions should the central unit of the automation system fail.

The calculation modules enable the configuring of individual user functions.

Coupling modules enable the connection of I/O modules over larger distances. They additionally enable use of non-intelligent I/O modules of the SIMATIC S5 programmable controllers, plus the ET 100U distributed I/Os for the automation systems.

Memory, configuring

The memory with battery backup of the automation systems is divided into:

•a system memory and

•a user memory.

The write-protected system memory contains the software which always belongs to the automation system, in the form of basic programs and function blocks. Far more than 100 standardized blocks are available for data acquisition, closed-loop control, open-loop control, calculation, supervision, logging, display and operation/monitoring.

•the central processor module,

•a memory module with user memory with 4,000 Kbyte capacity and battery backup and

•the interface modules for the input and output devices and the CS 275 bus system,

each of which is redundant in the AS 235 H system.

The central processor is microprogrammed and has a maximum processing width of 32 bits. Three basic cycles are present for processing (125 ms, 1 s and background level). An acyclic mode can also be defined.

The basic unit of the AS 235 and the basic system of the

AS 235 K each has 6 slots for I/O modules. No I/O modules can be plugged into the basic unit of the AS 235 H systems.

The following can be fitted into the systems as standard:

• AS 235 Max. 90 I/O modules

(basic unit + 6 extension units)

•AS 235 H Max. 91 I/O modules (7 extension units)

•AS 235 K Max. 108 I/O modules

(basic system + eight ES 100 K extension systems)

Instead of programming the system with individual commands and carrying out the required program tests, it is only necessary in the TELEPERM M process control system to configure these complete function blocks in order to obtain a “user program”. In the simplest case, configuring means calling the function blocks with the keyboard, several times if necessary, and then assign- ing the respective linking instructions and parameters. The resulting application-oriented configuring data are then stored in the user memory.

Configuring is possible before the automation system is started up as well as during operation. It is possible to temporarily switch partial functions of the user system out of operation for this purpose.

Convenient configuring using graphic inputs is possible using the PROGRAF AS+ engineering tool which can be executed in a personal computer connected locally to the AS 235/235 H/235 K automation system or centrally to the CS 275 bus system.

The number of usable I/O slots with the AS 235 and AS 235 H can be increased by additional use of ES 100 K extension sys- tems:

•AS 235 Max. 114 I/O modules

•AS 235 H Max. 103 I/O modules
