AC31 PLCs and previous series

AC31 and previous series (e.g. Sigmatronic, Procontic) are obsolete and were replaced by the AC500 PLC platform.

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.
