Fig. 2.1-1: Basic unit 07 KT 97 R0200

The basic unit 07 KT 97 R200 is the standard device for all applications. In addition, there are basic units with reduced

performance (e.g. 07 KT 95 or 07 KT 96) as well as ones with extended performance (e.g. 07 KT 97 R260 with

ARCNET connection, 07 KT 97 R0220 with PROFIBUS connection and 07 KT 97 R0262 with both ARCNET and

PROFIBUS connection). A comparison table is given on page 3. This document describes the basic unit 07 KT 97

R200 and then adds the data sheets of the other devices which only show the differences.

2.1.1 Brief description

The basic unit 07 KT 97 works either as

bus master in the decentralized automation system

Advant Controller 31 or as

slave (remote processor) in the decentralized automa

tion system Advant Controller 31 or as

stand-alone basic unit.

The basic unit is powered by 24 V DC.

2.1.1.1 Main features

24 digital inputs with LED displays

16 digital transistor outputs with LED displays

8 digital inputs/outputs with LED displays

8 individually configurable analog inputs 0…10 V,

0…5 V, ±10 V, ±5 V, 0…20 mA, 4…20 mA, differential

inputs, Pt100 (2-wire or 3-wire), the analog inputs are

also individually configurable as digital inputs

4 individually configurable analog outputs ±10 V,

0…20 mA, 4…20 mA

2 counters for counting frequencies up to 50 kHz, con

figurable in 7 different operating modes

1 CS31 system bus interface for system expansion

1 interface for connecting communication modules

(e.g. 07 KP 90)

2 serial interfaces COM1. COM2– as MODBUS interfaces and– for programming and test functions

Real-time clock

LEDs for displaying operating conditions and error

messages

Detachable screw-type terminal blocks

Fastening by screws or by snapping the device onto a

DIN rail

The lithium battery 07 LE 90 can be put into the

battery compartment in order to– store and backup the user program in the RAM– store and backup data which is additionally con

tained in the RAM, e.g. the status of flags– backup the time and date (real-time clock)

RUN/STOP switch for starting and aborting the pro

gram execution

Extensive diagnosis functions– self-diagnosis of the basic unit– diagnosis of the CS31 system bus and the

connected modules
