The fast and flexible communication library
Conventional PLCs are often the standard solution for automation requirements. For control systems with an increased computing time or large data collectives, PCs and server are the first choice. The connection of both systems is ACCON-AGLink’s mission. The communication library ACCON-AGLink arranges for a smooth data exchange between PC and PLC.
