Communication System
The KCS Communications Controller System is designed for a new basic system for communication and operation of intrinsically safe and non-intrinsically safe field instruments.
This centralized interface and supply unit, which is intended for installation in the safe area, consists of a communications processor (KCP) module and one or more communications interfaces, which are available in two different versions (KCI and KCI-Ex). The modular design allows to operate several interface modules with one Communications Processor Module KCP. Hereby the KCI-Ex interface serves as a supply and separation interface for one intrinsically safe TExi bus strand each. The KCI interface module is the separating interface to non-intrinsically safe field instruments. Interface modules of either type can be added to the KCS at random. This allows to optimally customise this central unit to the project's requirements. The modules are easy to install, and cost-efficient due to the new TExi bus technology when used for more complex field instrument topologies. There is no need to star wire the individual field instruments, but each of them works on one strand of the interface module.
The interface modules provide safe and accurate galvanic separation between the bus circuits and the processor module. In practice up to 10 Card Readers type KL-4 can be operated on one KCI-Ex for the ignition class IIB, for example. The max. number of devices that may be connected at a distinct interface depends on their current input, and on the specified ignition class.
Long lines (1200 m) are feasible, and a data transmission rate of 57.6 kbit/s is possible. This enables real-time capable applications with defined response times as the proprietary AMCC protocol runs without an expensive overhead.
The user side can be served by the communications controller system, such as via the Siemens PLC protocol SP3964. The installation can be configured and tested with a program supplied by us for this purpose.
KCS system with KCP and two interface modules KCI-Ex as well as one KCI interface module in the 19'' rack
Communications processor type KCPThe Communications Processor KCP is the central interface module. On the primary side, it has a configurable RS232 / RS422 / RS485 / TTY interface, and it enables different protocols. On the secondary side, the data are routed to the respective intrinsically safe and/or non-intrinsically safe field instruments via KCI interfaces. The KCP module is a modular component of the KCS Communications Controller System and serves as bus master for the field instruments and as gateway to superset control systems or process-management computers. |

Interface Typ KCI-ExThe Communications Controller Interface type KCI-Ex provides the intrinsically safe TExi bus. It serves as separation interface and power supply unit for the intrinsically safe field instruments (such as Card Reader type KL-4) and is a modular component of the Communications Controller System KCS. |

Interface Typ KCIThe Communications Controller Interface type KCI is the standard RS485 bus separation interface for connection of the non-intrinsically safe peripherals, and is a modular component of the Communications Controller System KCS. To one bus section can be connected explosion-proof as well as non explosion-proof field instruments with own power supply. |
