IEC 61131-3 standardises the programming language, the instruction sets and the handling and structuring of projects. This gives the ability to run programs generated by suitable programming tools using any of the 5 standards. As supplied, the IEC 61131 system will run programs for one hour after power-on, to allow engineers to try out their standard programs on the Motion Coordinator hardware. For continuous running, a software key (Feature Enable Code) must be bought for each MC464 that needs to run IEC 61131 programs.
