摘要:
A control network communication arrangement includes a second protocol embedded into a first protocol in a way that modules supporting the second protocol may be aware of and utilize the first protocol whereas modules supporting only the first protocol may not be aware of the second protocol. Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, the messages sent using the second protocol will be seen as messages sent using the first protocol but not having a message necessary to understand or as needing a particular response. In another approach, modules using the second protocol can be configured to send message during transmission of first protocol messages by other modules, the second protocol messages being triggered off of expected aspects of the message sent under the first protocol.

A first unit (200, 303, 304) works with analog and digital signals in physical sequences referring to one or several measurement objects (200′, 305, 307), which work with one or several functions (200″, 211, 302, 308, 309) and detectors (201, 202, 205) and/or control devices (212/214) detecting these functions. A distributed control system (206) works with a first protocol (218). The first unit (200) is connected to the control system (206) and is arranged, through its compatibility with the first protocol (218), to receive and/or send messages from/to the control system. The first unit (200) receives and sends physical signals for measurement and/or control of various types and combinations of functions and/or detectors or control devices, and processes the physical signals. The first unit is connected to a second connection (209) working with a second protocol (418). The second connection is in a link in a tool arrangement. The first unit communicates with a second unit (450 and/or 201, 221) via the second connection (209). The first unit van be set up via a connection that works with the first and/or the second protocol(s) or variant(s) thereof. In this way, more complex and simpler tasks can be dealt with separately, and can be divided up between different pieces of equipment and different people.

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.
摘要:
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.

In an arrangement, functions and/or structures in a distributed control system (24) that works with a first protocol (28) are analysed and/or monitored. A first unit (23) is connected or can be connected to the control system, which first unit, due to its compatibility with the first protocol, receives and/or sends task instructions concerning the functions and/or structures. The first unit comprises or is connected to a second (22) and transforms at least those parts in the first protocol that relate to the task instructions concerning the functions and/or structures into a second protocol, by means of which the said tasks can be initiated and/or carried out in a tool arrangement (1) that is comprised in or can be connected to the second unit. This tool arrangement works with the second protocol, whereby primary readings and/or modifications in the first protocol on the basis of the analysis and/or monitoring can be carried out by means of secondary readings and/or modifications in the second protocol. The analysis and monitoring are simplified and tools and protocol-handling can be separated. In addition, time functions in the system(s) can be made unambiguous.

A control or supervision system incorporates a digital serial communication and modules which are mutually communicable to this and operate with CAN-protocol. A control desk can be wirelessly connected to one or more modules operating with a signal protocol which takes no account of arbitration and/or confirmation functions appearing in the CAN-system. A particular receiving communication part executes the conversion of said signal protocol to the signal protocol of the CAN-system. A device for controlling a function in a first module in a CAN-system via a wireless connection to a second module in said system. A system of mutually separate units, whereof each unit operates with a CAN-signalling protocol, intercommunicable by means of radiocommunications operating with an identification system in which a key allocation between the units is based upon identities that are assigned by a module in the unit or a master system.

摘要:
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.
