A system for controlling, monitoring, communicating, etc. comprising a plurality of module units. The system further comprises at least one connection facility comprising a first contact unit and a second contact unit. The first contact unit connects at least one of the plurality of module units to a system connection. The second contact unit is configured to communicate information via the system connection using a first protocol and to communicate information with the at least one module unit using a second protocol. Individual ones of the second contact units further comprise at least one processing device configured to convert information in the first protocol to information in the second protocol for the at least one module unit, the at least one processing device configured to convert information in the second protocol to information in the first protocol for the distributed system.

Communicating with a first and second protocol

A device suitable for use as a module in a Controller Area Network (CAN) system with a bus or connection includes relatively simple and inexpensive components, including an oscillator that generates a number of different frequencies in response to directions from a microcomputer. A CAN Controller receiving the frequencies is connected to the bus via a transceiver. The device has utility for verification and validation work in association with a CAN system.

An arrangement for a system for controlling, monitoring, communication etc. comprises locally deployed module units which each perform one or more local function(s). The system also comprises one or more system-functioning-determining unit(s) at a higher level than said module units. Also included are one or more connection(s) connecting said units. Each module unit is connected to the connection concerned via a connection facility or connection point. The facility or point comprises one or more microprocessor(s) (microprocessor setup(s)) arranged with compatibility with signalling appearing on the connection according to the rules of systems engineering which apply, and with a higher-level function in relation to the module unit. The invention also relates to a method for said system and a contact arrangement for connection of a module unit to the connection. The invention makes possible outstanding separation of system functions and module unit functions, the result of which is that the various part functions can be produced individually with hardware and used by the system/module unit constructor.

In a distributed control system for one or more machines and/or one or more processes, data and control commands are transmitted via radio connections between nodes in the control system. The nodes operate with radio transmitters and radio receivers and comprise or are controlled by activation devices for activating their transmission and receiver functions. The nodes also operate with time-determination devices which comprise or control the abovementioned activation devices. The time-determination devices are arranged to determine the transmission or reception position of the nodes by means of the activation devices and allocated settings or controls. The abovementioned settings or controls can be determined by means of one or more schedules implemented in or for the control system, in which the nodes are given unique or co-ordinated transmission and reception times on the radio connections.
