A command sequencer is a tool that can be used to configure, test, and execute command sequences. A multi-system command sequencer block diagram is most useful when one needs to perform the same processing operations on a set of similar entities. Following the pre-and-post observing tools, the user interface will provide the multi-system command sequencer. As per the image, the AO Controller will pass along the information to different interfaces and sequencers like laser sequencer, laser traffic control system, data server interface, and instrument sequencer, and others. Instead of creating a multi-system command sequencer block diagram from scratch, use EdrawMax pre-defined templates as it provides the right facts and figures that ease the entire process.
