KUC755AE106 3BHB005243R0106 Excitation module

The central unit 07 KT 93 works either as
bus master in the decentralized automation system ABB Procontic CS31 or as
slave (remote processor) in the decentralized automation system ABB Procontic CS31 or as
stand–alone central unit. The device has a 24 V DC power supply voltage. It is provided with an additional interface for connecting communication modules (e.g. 07 KP 90). The central unit 07 KT 93 R171 is equipped with an integrated ARCnet coupler (and an ARCnet interface). 3.1.1 Main features
24 binary inputs
16 binary transistor outputs
1 counting input for counting frequencies up to 10 kHz
1 CS31 system bus interface for system expansion
Serial interface COM1 – is set as programming interface – can be set as an ASCII interface for connecting peripheral devices (e.g. MMC devices)
Serial interface COM2 as an MMC interface
ARCnet coupler / ARCnet interface (version R171 only)
Real–time clock

Project planning / start–up 

The following has to be observed for project planning and start–up:
Programming is performed using ABB Procontic programming software, which can be run on commercially available IBM compatible PCs (see documentation for the programming system 907 PC 331)
Diagnosis and service device TCZ (terminal mode) (see volume 7.3, see chapter A5 (Appendix), Programming and test, see 3.3.10 Serial interface COM1)

LEDs for displaying the binary input and output signals as well as operating conditions and error messages
Detachable screw–type terminal blocks
Detachable plastic sheet on the front side of the device; can be labelled with the signal names in order to have the inputs and outputs directly assigned
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 back-up the user program in the RAM – store and back-up data which is additionally contained in the RAM, e.g. the status of flags – back-up the time and date (real–time clock)
RUN/STOP switch for starting and aborting the program execution.

The processor processes

 the user program contained in the RAM. It is loaded into the RAM via the serial interface COM1 and can also be changed there. An additional save command is used to save the program in the Flash EPROM. Note: In the course of the following operations – Power ’ON’ – RUN/STOP switch from STOP ––> RUN – Program start-up with programming system – Cold start of the PLC the RAM is overwritten by the contents of the Flash EPROM, if a user program is contained in the Flash EPROM.
On-line program modification The two existing RAMs allow a quick modification of the user program to be performed without interrupting the operation (see ABB programming system 907 PC 331).
Change-over between the application modes – Stand–alone central unit – Bus master central unit and – Slave central unit The central unit is set to ”Stand-alone” upon delivery. Changing the application mode is carried out in the following three steps: 1. Change the system constant KW 0,0 in the PLC, see chapter A7.3 (Appendix), System constants 2. Save the user program in the Flash EPROM 3. Activate new application mode by: – calling up the menu item of ”Enable PLC mode” in the ABB programming and test system or – performing a warm start or – performing a cold start
