Best practices in the PLC programming realm, uses Static Analysis (verification testing). It is probably one of the least covered in PLC training, and therefore least practiced. (With those receiving BIN95 PLC training being an exception to that rule as they have always covered it in the instructor based classes since 1995.) Yet it should be one of the most important parts of the automation control design phases.
The most important being Safety, Maintainability and Cost Savings over the life cycle of the equipment that PLC code controls. Many machine designers and system integrator claim they do not have the budget to do static analysis to GAMP 5 level of quality. The cost of not doing so, is passed on to you (the end-user of the equipment) for the life of the equipment.
That cost to end-user, when measured in using TDC (True Downtime Cost), can and often is … astronomical over the life of the equipment.
What does OPC stand for? OPC = OLE for Process Control
What does OLE stand for? OLE=Object Linking and Embedding
OPC communication protocol is the most current to standardize data transfer between all industrial devices. Which make OPC training essential to those working with IIoT.
(IIoT=Industrial Internet of Things)

ME aptitude tests (MAT) are one of the most common, they measure knowledge of mechanical engineering technology, electrical, and physical concepts.
The article above covers how to study for the mechanical aptitude test (MAT) that are commonly used today. There is mechanical aptitude test preparation for Bennett (BMCT test), the Wiesen test (WTMA test), the Ramsay Corporation test and the Military’s ASVAB test preparation.
As well as the Military using the ASVAB for pre-screening, big corporations like Delta airlines, AT&T, Dupont, and Amtrak.
Bennett test (BMCT test) – Used for industrial and repair positions jobs.
Wiesen test (WTMA test) – Used in the operating, maintaining and repairing machinery industries, and deals more with day to day operations.
Ramsay test – Used to identify and sort potential candidates for trainee programs and apprenticeships.
ASVAB test – Used by the military as mechanical aptitude test. Includes questions about general science, electronics information, auto information, shop information and mechanical comprehension.
A ControlLogix – RSLogix 5000 Tutorial
Check out the RSLogix 5000 Tutorial to get started with understanding the structure (architecture) PAC RSLogix 5000 programming.
A ControlLogix project is comprised of tasks that contain programs routines and other elements. Tasks within the project set the execution priority for one or more programs and schedule the program’s execution with up to 32 tasks available.
The programming task are configured to execute …
Continuous: The continuous task is executed continuously as long as periodic or event tasks are not being executed. When the continuous task completes a full scan, it restarts immediately.
Periodic: Periodic tasks perform a function at a specified interval. Configurable time periods range from point 1 milliseconds to 2,000 seconds. Priorities assigned, range from 1 to 15.
or Event-based:Event task are executed immediately when a specific trigger occurs. A trigger is defined by the user and can be a change of state of an input or specific motion control operations.
In summary tasks are executed one at a time depending on their priority and only one task is continuous.Learn more see RSLogix 5000 Tutorial

Below is a link to a great whitepaper about the learning path for PLC network Communication to PC (HMI SCADA), to the Smartphone (cloud). More accurately PLC to OPC/SQL to Smartphone App or HTML5. Includes network security advice for the stages alogn the way too. Start with PLC network and communication protocols and methods, then expand to HMI-SCADA, to SQL (and brand specific topics like RSLinx OPC server), Excel OPC client, HTML5 and your ready for Smartphone.
