– 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

· Integrated Flash EPROM for storing program and data

· Exchangeable SmartMedia Card 07 MC 90 for user

data or for updating the operating system or PLC pro-

gram

2.1.1.2 Project planning / start-up

The following has to be observed for project planning and

start-up:

· Programming

is performed with AC31 programming software, which

can be run on commercially available IBM compatible

PCs (see documentation of the programming system

907 AC 1131).

· Online program modification

A quick modification of the user program is possible

without interrupting the operation (see programming

system 907 AC 1131).

· Possible operating modes

– Stand-alone basic unit

– Bus master basic unit

– Slave basic unit

· Backup of data areas,

i.e. saving of data during power OFF/ON, is possible

with an integrated battery and/or

by storing them in the Flash EPROM.

The basic units of this intelligent decentralised automation system: 07 KT 95, 07 KT 96, 07 KT 97 and 07 KT 98 are available in four models, which differ in their performance and functional configuration.

Differences in the number of digital and analogue I/Os: the 07 KT 95 has 12 digital inputs, 8 digital outputs, 4 analogue inputs and no digital I/O ports; the 07 KT 96 has 24 digital inputs and 16 digital outputs but no analogue inputs; the 07 KT 97 and 07 KT 98 both have 24 digital inputs, 16 digital outputs, 8 digital I/Os, the 07 KT 97 has 8 analogue inputs and the 07 KT 97 has 8 analogue inputs. Both 07 KT 97 and 07 KT 98 have 24 digital inputs, 16 digital outputs, 8 digital inputs/outputs, 07 KT 97 has 8 analogue inputs and supports Pt100, 07 KT 98 is the same as 07 KT 97 in terms of analogue inputs.

Difference in processing time: Typical processing time for 1kB programme is 0.3ms for 07 KT 95, 07 KT 96 and 07 KT 97 and 0.07ms for 07 KT 98, 07 KT 98 is faster.

Differences in integrated functions: The different models are available in several versions with different integrated internal couplers. For example, the 07 KT 97 is available with different combinations of ARCNET, PROFIBUS - DP, Ethernet, CANopen, etc., while some versions of the 07 KT 95 and 07 KT 96 have similar integrations, but in different combinations than the 07 KT 97.
