The comprehensive description

 for this central unit is located in part 4 of this volume. The same description is available as an operating manual, order No. GATS 1316 01 R2001. Brief description The central unit 07 KR 91 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 CS 31 or as ● Stand-alone central unit. The module is provided in two versions with supply voltages of 24 V DC and 115/230 V AC : 07 KR 91 R101 : The device has a 115/230 V AC power supply voltage. It provides a 24 V output voltage for the supply of its own binary inputs. 07 KR 91 R151 : 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). Both module versions have the following main features : ● 20 binary inputs ● 12 binary relay outputs ● 1 counting input for couting frequencies up to 10 kHz

Central unit

● Central unit for an user program containing ma. 7 k of instructions ● 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) ● Real-time clock ● 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 on 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 ● Extensive diagnosis functions – Self-diagnosis of the central unit – Diagnosis of the ABB Proncontic CS31 system bus and the connected modules
