Abstract: A system for servicing field devices in an automated plant with a superordinated control/service unit, wherein the superordinated control/service unit accesses the field devices via a communication network. The communication network has at the control/servicing level a first bus system with a first transmission protocol and at the field level a second bus system with a second transmission protocol. The conversion of the two transmission protocols occurs in a gateway and provided in the gateway a basic software, which, upon the occurrence of an event, scans to ascertain the field devices arranged at the field level and utilizes the ascertained information concerning the field devices, in order to download the corresponding electronic device descriptions from an application server and to provide these to the control/service unit for servicing the field devices. The application server contains server apps.

Abstract: A process control arrangement (PKA), having a number of fieldbus systems (DP1, PA1, FH), especially different fieldbus systems (DP1, PA1, FH), and having a number of fieldbus interfaces (PAP1, PAP2, PAP3), wherein each of the fieldbus systems (DP1, PA1, FH) is connected to at least one of the fieldbus interfaces (PAP1, PAP2, PAP3), wherein the fieldbus interfaces (PAP1, PAP2, PAP3) serve for communication between the fieldbus systems (DP1, PA1, FH) and a communication plane (ET2) superordinated to the fieldbus systems, only a first of the fieldbus interfaces (PAP1) is directly connected to the superordinated communication plane (ET2), and wherein the fieldbus interfaces (PAP1, PAP2, PAP3) are connected in series with one another beginning with the first of the fieldbus interfaces (PAP1).

Abstract: A method for residual stress enhancement for a coil spring includes radially expanding at least a select axial portion of the coil spring to remove residual tensile stress from the spring inner diameter and induce residual compressive stress in the spring inner diameter. The spring is expanded by radial force on the inner diameter and/or by a helical unwinding force induced by rotating at least one end of the spring relative to the other end of the spring. A tool includes a spring expansion portion and, optionally, a diameter control portion. Cylindrical, conical and/or beehive springs are processed to enhance residual stress.
