The Logix world does things its own way: there are no memory addresses anywhere, and every value is a named tag. Your program is a tree of Tasks → Programs → Routines, logic you reuse becomes an Add-On Instruction, and controllers swap data as produced/consumed tags over EtherNet/IP. Learn it on the machines North America runs.
How Logix executes: one Continuous task plus Periodic and Event tasks, each holding Programs, which in turn hold Routines that call each other. On a palletizing line, you watch a live scheduler run a continuous task while a periodic task preempts it.
Logix has no %I0.0; every value is a named tag with a data type. The track covers controller-scoped tags that every program sees vs program-scoped tags that stay private, base vs alias tags, and why the tag database is the program.
The Logix way to package logic: build an Add-On Instruction once, with its own parameters and local tags, and drop it in like a built-in instruction. AOIs are versioned and can be source-protected, which makes them the backbone of a reusable standard.
Ladder rules the Logix world, but FBD, Structured Text and SFC are available too. You get the same conveyor seal-in in each, and straight guidance on when ladder gives way to ST.
How Logix controllers share data: produced/consumed tags pushed over the backplane & EtherNet/IP, the MSG instruction for on-demand reads/writes, and connection budgeting.
Add a module, set its RPI, and its tags appear in the I/O tree automatically. CIP implicit vs explicit messaging, the connection model, and how Logix maps a remote rack into named tags.
Integrated motion the Rockwell way: motion groups, axis tags, the MAM/MAJ/MAS instructions, and CIP Motion synchronising Kinetix drives over EtherNet/IP.
Safety on the same controller: the dedicated safety task, safety tags & the safety signature, certified safety instructions, and how the safety and standard worlds coexist on a GuardLogix.
Debug the Logix way: going online with live ladder, watch & trends, the controller log & faults (major/minor), forcing I/O, and tracing an intermittent fault to ground.
The bigger picture: Logix Designer vs the legacy RSLogix 5000, FactoryTalk View for HMI, the controller families (ControlLogix, CompactLogix, GuardLogix), and how a project hangs together.
Give the line a voice: instruction-based ALMD/ALMA alarms in the controller, tag-based alarms on the server, and an acknowledged, time-stamped audit trail of what tripped and when.
The window into Logix: View ME on PanelView terminals vs SE for plant-wide SCADA, FactoryTalk Linx shortcuts, and the main attraction, which is binding displays straight to controller tags. Run a live PanelView mock, then flip it into design mode to see the tag bindings underneath.
The hardware in detail: the controller ladder from Micro800 (Connected Components Workbench) through CompactLogix to ControlLogix, with every generation (5370→5480, 5570→5590, Micro810→870), GuardLogix safety, and which tool programs each.
The window into Logix: a live PanelView mock where push buttons write controller tags, displays read them, and a design-mode toggle shows the direct tag bindings underneath. It also covers the ME vs SE decision every plant has to make. Now live, so open it →
