From the original programmable logic controller (PLC) invented in the 1970s to the scalable, multi-disciplined and information-enabled programmable automation controller (PAC), Allen-Bradley® control systems help you meet complex to simple application requirements. PLC (av engelska programmable logic controller) eller programmerbart styrsystem är ett slags dator som främst används inom automation, till exempel för att styra en montagelinje, ett vattenkraftverk eller åkattraktioner på ett nöjesfält. and PLC Systems SECTION 5 Advanced PLC Topics and Networks Industrial Text & Video Company 1-800-752-8398 www.industrialtext.com Each of these types of AI systems have similar characteristics, and in fact, the systems evolve sequentially. As the systems become more sophisticated, the In case of PLC systems, PLC were not suppose to be in packages but competition with DCS vendors forced the PLC manufacturers to offer necessary all other softwares and packages. 3) Many DCS are designed such that it is possible to configure cycle time for each Functional Block. The PLC signals are transmitted to the active or passive components via 40-pole or 10-pole pre-assembled control cables. The PLC signals are converted either: • in double-word form via a flat-strip connection or • byte-for-byte via 10-pole flat-strip connections System cabling The basic principle is to connect PLC-specific front adapters to A PLC is an example of a hard real time system since output results must be produced in response to input conditions within a limited time, otherwise an unintended operation will result.
