Issue Historically, picking a date in Citect has always been achieved using the Microsoft Date and Time Picker Control 6.0 Active X object that comes along with most Windows installation. However, as time progresses on, this Active X is no longer as popular as it used to be. Often, projects which uses the Active X, which are migrated from older systems into a new Windows 10 or above environment will fail on Compile. And installing the Active X is often difficult because it may require installing a whole bunch of un-related software just to get it. And many times, even with the Active X already in the environment, the project still does not Compile, or fail to run properly. Resolution There is an alternative to using Date and Time Picker Control 6.0 Active X and this article is to introduce how to use the Calendar Genie in lib_controls Library to do that. It will involve the implementation of a Callback Function, and this article explains how this is to be created and used.

Issue Sometimes we need to do modifications and new development in an application offline, but we can't stop the controller when it's time to download the changes. Resolution With Modicon M580 redundant is possible implement offline modifications without stop the application using the HSBY_BUILD_OFFLINE library.

Issue You're targeting a palletizing application or an application where you have evenly spaced action points (e.g. drilling in material working) and don't want to teach all points separately. Resolution The Pallet application instruction offers an interface to easily teach endpoints and distributes points in between evenly, based on the instruction setup. The instruction helps setup the action points and encapsulates instructions to be performed at each waypoint.

Issue The IEC 61131-3 not only describes the PLC programming languages themselves, but also offers comprehensive concepts and guidelines for creating PLC projects. Defined in IEC 61131 standard, a Program Organization Unit (POU) provides a modular and hierarchical way of structuring programs that makes it easier to develop, debug, and maintain industrial control programs. How will this concept be used to organize and structure industrial control programs? Resolution In this document the term POU is used for programming elements in general that can contain IEC code, such as methods, properties, interfaces etc. The term Program Organization Unit (POU) is used for all programming objects (programs, function blocks, functions, etc.) which are used to create a controller application.

Issue The configuration of an MMM system with routes, starting and stopping assets in sequence, taking into account security and associated supervision, is not easy to achieve. Resolution EcoStruxure Process Expert and the MMM library allow to realize these functions and the associated supervision by simple parameterization. The document presents the functional description of an MMM process managing conveyor belts, valves and tanks and how to develop the system with a group control function used to start and stop the assets in sequence.

Issue Using C # code for HMI in EcoStruxure Automation Expert is essential to create advanced features in CAT objects. We can mention, among others, custom properties, security, hardware CATs and all the advanced features that can be provided by C #. Resolution This document provides the information on how to use Visual Studio Community for the adjustment of the program in EcoStruxure Automation Expert.

Issue There are two available solutions to implement time stamping with EcoStruxure Control Expert, both methods are easy to implement and can be selected for use in almost any circumstance. Applicative – A function block is required for third-party SCADA to convert and read the information System – No programming is required (some components are needed) System and Applicative time stamping modes are exclusive in the same EcoStruxure Control Expert application running in the controllers. In this article, we will investigate the System Time Stamping solution. Resolution System Time Stamping provides a consistent SOE (sequence of events), time stamped at the source, to allow the user to analyse the source of abnormal behaviour in a distributed automation system. The SOE is displayed in an alarm summary or SOE page of a client (such as a SCADA). Each source of time stamped event of the SOE is a discrete I/O value change (transition) detected by a time stamping module, this event is then passed through to OFS and straight to the SCADA.

Issue How do I use EcoStruxure Machine SCADA Expert - Asset Link to create objects within EcoStruxure Machine SCADA Expert. Resolution The purpose of this document is to introduce EcoStruxure Machine SCADA Expert -Asset Link and to highlight the basic steps to pattern creation and using the software tool with EcoStruxure Machine SCADA Expert.

Issue The Modicon M580 Safety controller can execute single task and multi-task applications. Unlike a single task application which only executes the MAST task, a multi-task application defines the priority of each task. When a task is running, it can be interrupted by another task with a higher relative priority. For example, when a periodic task is scheduled to execute its code, it would interrupt a lower priority task, but would wait until the completion of a higher priority task. Resolution For optimal CPU performance, Schneider Electric recommends that the total percentage of CPU bandwidth consumed by an application not exceed 80%. Users will need to determine the CPU bandwidth and fine tune to adjust the tasks period for an optimal CPU performance.

This document presents different ways to change the animation color of the common process library objects in EcoStruxure Automation Expert. 3 methods are presented: a simple method using the standard parameters to modify the color animation of all objects in the library. A static method using the instance properties to customize the animation color of each instance. A dynamic method to change the animation color of an object, directly from the logic. Example of dynamic color change: These methods can be applied to change the color of any graphical objects. The Solution archive example is attached ( EcoStruxure Automation Expert V22.0)
