Abstract: The invention relates to a method for transmitting data between a first automation appliance, and at least one second automation appliance, via a CANopen bus using a service data object as an SDO service, wherein an SDO client implemented in the first automation appliance is used to send a download or upload request to an SDO server implemented in the at least one second automation appliance, wherein the data are encapsulated in a CANopen frame by an application implemented in the first automation appliance or the at least one second automation appliance wherein the CANopen frame with the encapsulated data is transmitted or sent by means of an SDO service into or out of a data tunnel object defined in an object dictionary of the SDO server, and wherein the encapsulated data are decapsulated by the application implemented in the first or the at least one second automation appliance.

Abstract: A modular distributed I/O system for an industrial automation network that allows one or more modules of an island to be omitted without requiring reconfiguration of the system by maintaining a consistent I/O image representation of the distributed I/O network for various physical distributed I/O configurations, and managing reconfiguration changes using Virtual Placeholder objects.

Abstract: The invention described herein provides a system and method for distributing and applying a configuration file from a master device (102) to a slave device (104) in a distributed control system (100). According to aspects of the invention, a configuration file is saved at a master device (102) and distributed to the slave device (104) via the data payload of a fieldbus protocol, such as the CANopen protocol. Aspects of the present invention may be used to further configure an I/O island or sub-network (108) that is attached to the slave device (104). Further aspects of the present invention may be used to repair or replace failed devices in a distributed control system (100).

Abstract: An transfer body is provided for interfacing between field devices and a field master. One form of the transfer body is an input/output (IO) body. The IO body has a plurality of in-data registers for accepting data from the field devices, a plurality of out-data registers for sending data to field devices, and an identification register for identifying the data in relation to the field devices. The IO body also has an interface portion having an identification port communicating with the identification register, an in-data port communicating with the in-data registers, and an out-data port communicating with the out-data registers. The body can directly attach to and communicate with a plurality of different types of communications adapters through the interface portion for communication with a field master. The body can also directly attach to and communicate with a PLC type of field master through the interface portion.

Abstract: The invention relates to a process for the production of solutions of substantially water-insoluble complex antimony compounds in polar organic solvents by esterifying an .alpha.-hydroxy polycarboxylic acid with a polyol, reacting an excess of the esterification product with an antimony oxide in a polar organic solvent and reacting the free carboxylic groups with a monoisocyanate.

Abstract: The invention relates to a process for the production of allyl or methallyl phosphonic acid dialkyl esters by reacting allyl chloride or methallyl chloride with trialkyl phosphites at temperatures of from 80.degree. to 160.degree.
