Programmable Controllers: An Engineer's Guide focuses on the application and use of programmable controllers, including programming techniques, good software practices, and software engineering. The monograph first takes a look at computers and industrial control and programming techniques. Discussions focus on programming methods, bit storage, counters, timers, identification of input/output and bit addresses, input/output connections, types of control strategies, and advantages of PLC control. The manuscript then examines programming style and analog signals, closed loop control, and intelligent modules. Concerns include intelligent modules, specialist control processors, software engineering, program structure in various PLCs, and housekeeping and good software practices. The publication tackles practical aspects, industrial control with conventional computers, man-machine interface, and distributed systems. Topics include parallel and serial communications, ISO/OSI model, serial standards, simple digital control and indicators, computer graphics, maintenance and fault finding, and programming for real time control. The monograph is a valuable reference for computer science experts and researchers with a keen interest in programmable controllers.
