ABB AC31 PLCs and previous series

The Advant Controller 31 series 40-50 offered small and compact PLCs with central and decentralized extensions. The Advant Controller 31 series 90 offered powerful PLCs for challenging applications with various configuration options and up to five communication interfaces. The PLC provided 60 I/Os internally and could be expanded decentrally. The combination of integrated communication fieldbus allowed to connect the PLC to several protocols like e.g. Ethernet, PROFIBUS DP, ARCNET or CANopen.

Both AC31 series 40 and 50 utilized the same AC31GRAF software which conformed to the IEC61131-3 standard. AC31 series 90 utilized the 907 AC 1131 programming software, also developed in accordance with IEC61131-3.

The Advant Controller AC31-S was available for safety-related applications. It was based on the time-proven system structure of the AC31 series 90 variant.

Machines and plant equipment, for reasons of competitiveness are becoming even more complex, the amount of information required from sensors and actuating devices is constantly expanding, causing heavier implementation and higher wiring costs. The ABB Procontic CS 31 is designed to simplify implementation and wiring. The CS 31 is a decentralized automation system. The system is ideally suited to applications where modularity and cost reduction are key factors. The CS 31 system comprises of the following : – a central unit, enclosed within a compact case which can be screw or DIN rail mounted, – remote input/output plug-in units, wich are easily removeable. The plug-in base can be screw or DIN rail mounted, – a simple twisted pair wire arrangement (RS 485), which is utilized for connection of the central unit to the I/O units.

The CS 31 is based upon two types of central units, 07 KR 91, 07 KT 92/07 KT 93 and 07 KR 31/07 KT 31. The system can be configured to comply with most control system requirements (See previous configuration examples). ● 07 KR 91, 07 KT 92/07 KT 93 is designed for complex applications with an higher level of functionality (Data manipulation, PID regulation, etc...). 

● 07 KR 31/07 KT 31 incorporates all of the functions required for smaller decentralized applications, thus providing an excellent Price/Performance ratio.
