Programmable Logic Controllers Basic Level TP301 – Festo Didactic GmbH & Co – 1st Edition

The programmable logic controller represents a key factor in industrial automation. Its use permits flexible adaptation to varying processes as well as rapid fault finding and error elimination. This textbook explains the design of a programmable logic controller and its interaction with peripherals.

One of the main focal points of the textbook deals with the new international standard for PLC programming, the EN 61131-3 (IEC-61131-3). This standard takes into account expansions and developments, for which no standardised language elements existed hitherto. The aim of this new standard is to standardise the design, functionality and the programming of a PLC in such a way as to enable the user to easily operate with different systems.
