    The XL8’s operating system is Linux, which is an open-source, stable, proven operating system (OS). Linux is used in many mission-critical applications worldwide and has allowed Midas’ software engineers to write a ground-up system that contains no ‘hidden’ or unused code. This has resulted in an efficient, compact application, which is quick in operation, quick booting and comparatively easy to debug.

  • Page 66: Replacing A Module

    Chapter 7: Operation Replacing a module The design of the DL451 Modular I/O makes module replacement very easy and straightforward. The unit has rack guides in each of the three module positions so that the modules can slide easily in and out. Each module is held in place by two screws, at the left- and right-hand sides, and a short metal post (or stud) adjacent to each screw facilitates removal.
