control of Quality is becoming increasingly important in the process industries because attention to quality produces substantial financial rewards. Manufacturing facilities that are concerned with quality control require timely and accurate transfer of data from laboratories to production operations. Once lab data reaches operations, decisions must be made about actions to be taken to control quality. Implementation of these actions must frequently be taken through control systems supplied by more than one vendor. Supervisory control systems linked to laboratory automation systems, distributed control systems, and programmable logic controllers can provide the means for timely data transfer, quality control decisions, advancedcontrol actions, and notification of personnel of quality control status.

The author describes the various important aspects of quality documentation for software used in industrial environments. Since the vast majority of these industrial applications use programmable logic controllers (PLCs), he concentrates on the specific documentation of PLC type devices. Highlights of the paper include a historical overview of significant developments in the field, current features using laptop personal computers, and future trends including advanced concepts. It is emphasized that PLC documentation can no longer be viewed as a stand-alone process but should be incorporated into a complete and comprehensive design package.< >

The author documents tradeoffs involved in designing an IEEE P1149.1/Joint Test Action Group (JTAG) scan bus master (SBM) that can operate at 25 MHz and interfaces a parallel host processor data bus to the serial P1149.1 test bus. By controlling the bits and all P1149.1 protocol for the host through an external device, the speed of running tests and scanning data is increased. Speed and throughput improve as more functions are implemented in controller hardware and fewer in host processor software. However, some advanced features require additional pins. Since the desired goals were a smaller part to fit more easily in a UUT (unit under test) and lower device cost, not all of the high-end functions were attained. The goals for the SBM were to maximize capability within the limit of device size, to be able to work in an IBM PC test station, and to be upwardly compatible with future products. Tradeoffs made for host synchronization, scan throughput, and more flexible commands reduce processor software overheard and improve scan and test rates. Evidence so far indicates that the SBM has met these goals. Prototype parts tested in a PC-based test system functioned as expected.< >

This paper explores some new ideas for improving the CRT display arrangement for digital distributed processcontrol systems. These ideas are formulated based on the authors experience in operating many existing digital distributed control systems utilized for advancedprocesscontrol. This paper presents a more flexible controller group arrangement which will increase the operator's understanding of the advancedcontrol strategies and the entire control status of a process unit. This improved display is a natural extension of the existing group to display and is a result of integrating ideas from advancedautomation concepts which consider the control algorithm design, process model development, optimization application, practicality of advancedcontrol implementation, clarity of the operator communications with control strategies and the processes, and on-line, real-time simulation application, etc.

The implementation of a plan to upgrade and expand the control and information systems of a brewhouse is discussed. The author describes how the integration of a cell controller, PLCs (programmable controllers), and a variety of intelligent devices made it possible to focus on improved process accuracy and repeatability, resulting in a higher-quality lower-cost product. Descriptions are given of the process application, the control system, and the information system.
