About this course

Digital I/O tells you whether something happened. Instrumentation tells you how much, how fast and how full, and it is where most of the field problems live.

The first half is analog: current loops and voltage signals, two-, three- and four-wire transmitters, shielding, and why the zero sits at 4 mA rather than 0. You configure a 1769 analog module, scale raw counts into engineering units, and alarm on a signal that goes out of range.

The second half is IO-Link, which is what a lot of new plants are actually installing. Masters and devices, process data against parameter data, finding and installing an IODD, assigning devices to ports, and reading what comes back.

The lab commissions a level sensor and a flow sensor end to end, then hands you one that is reporting nonsense and asks you to work out why.

What you work through

Modules

  1. 1

    Analog signals in a control system

    Current loops and voltage signals, two-, three- and four-wire transmitters, resolution, shielding and noise, and why the zero is at 4 mA.

    Available now 7 slides ~60 min 60 min lab
  2. 2

    Adding analog I/O to the controller

    Configure a 1769 analog module, choose a range and filter, convert raw counts to engineering units, and alarm on a signal that goes out of range.

    Available now 7 slides ~60 min 60 min lab
  3. 3

    IO-Link fundamentals

    Masters and devices, standard I/O mode against IO-Link mode, process data against parameter data, and what IO-Link gives you that a 4-20 mA loop cannot.

    Available now 7 slides ~60 min 60 min lab
  4. 4

    IODD files and commissioning a master

    Find and install an IODD, add the master to the I/O tree, assign devices to ports, and read the process data the device is reporting.

    Available now 7 slides ~60 min 60 min lab
  5. 5

    Level and flow measurement lab

    Commission a level sensor and a flow sensor end to end (configure, scale, alarm and trend), then diagnose one that is reporting nonsense.

    Available now 7 slides ~60 min 60 min lab

Lab times are approximate: they are a guide to how long the hands-on part usually takes, not a limit. You can ask for more lab time whenever you need it.

Where this course is up to

This course is in development. The module list is the curriculum plan, the slides, labs and knowledge checks are still being built, which is why every module reads COMING SOON.

The controller itself is in the lab and working. Other hardware is being added over time as the lab grows, and no course here opens for booking until both its hardware and its material are ready.

The IO-Link master and the level and flow sensors for this course are not in the lab yet.
