Basic Unit 07 KT 97 Basic unit with max. 480 kB user program + 256 kB user data, CS31 system bus 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.
