Issue In EcoStruxure Automation Expert V23.0, a new "Alias Name Toggle" button has been added. However, the documentation for this button is not available yet. Resolution The purpose of this document is to show how it is used to display Instance Name, Asset Tag name or HMI alias information. Disclaimer The views and opinions expressed in this article are those of the author(s) and do not necessarily reflect the official policy or position of Schneider Electric.

Issue SE.AppCommonProcess and other SE libraries offer the ability to show or hide the tag name on symbols used in graphics screens, but this function is not available when you create your own CATs. Resolution The aim of this document is to show you how to use the Tag Name Visibility in your own CATs.

Issue I want to have multiple engineers working on my EcoStruxure Automation Expert Solution. Resolution This article describes the main features of EcoStruxure Automation Expert Sub Versioning, and how they can be used to allow multiple engineers to work on the same solution concurrently.

Issue It is often a puzzle to many on where C# comes into play in EAE. Well, C# “lives” in the HMI and are found beneath Symbols that we create as part of a CAT. The next question then comes on how does the C# Codes get called to execute, where exactly is the entry point? And after, how do we debug our codes, or at least know what our codes are doing? Resolution This Knowledge Base article is meant to “demystify” the questions raised by letting us operate on a sample Solution provided. By the end of the lesson, we will: Understand the structure of C# Codes in EAE and how it interacts with HMI. Learn a quick and dirty way of Debugging our C# Codes using .NET MessageBox method.

Issue When it comes to dealing with IIoT solutions with EAE, NETIO Basic Function Block is one of the most useful to handle interactions with cloud services. However, the help file does not elaborate in detail how to use it. Resolution Understand how NETIO is to be used for a HTTP Post with an example application. We will also get to see how the response should be handled.

Issue How can I obtain data values from any Modbus devices utilizing the State RAM topological objects (%MW, %M, %S, %SW, %KW, %I, and %IW) via EcoStruxure OPC UA Server Expert without having to install the EcoStruxure Control Expert programming software? Resolution Using the EcoStruxure OPC UA Server Expert Configuration Tool, enable the Populate option, we can use topological addressing to retrieve data values from the EcoStruxure OPC UA Server Expert without the requirement to create located and unlocated variables in EcoSruxure Control Expert.

Issue A security database was created with the Security Editor tool on a PC where an old version of EcoStruxure Control Expert is installed (i.e. version 15.0). Then, a newer version of EcoStruxure Control Expert is installed (i. e. version 16.0) on the same PC. How to avoid creating the entire security database from scratch after installing a newer version of EcoStruxure Control Expert. Resolution Use the Security Database Migration Tool to migrate the previous security database to the one that is automatically created as part of the installation process of EcoStruxure Control Expert V16.0.

Manage forced variables in a PLC program has been a challenge on the industry for decades. Ideally every plant manager wants a ZERO force policy but in real world this not possible and eventually a force must be put in place to ensure production KPIs. Then the challenge becomes how to manager those forces. The solution to manage forces is to give full transparency by showing the status of forced variables in a SCADA system where operation managers and maintenance managers could see and take the needful action to replace the damaged sensors and then removed the forces in the PLC program. This KB shows an easy way to manage forces through the OPC quality code by displaying it in the supervision system.

Issue EcoStruxure Control Expert doesn't provide Double length real calculation functions. Resolution This library performs Long real calculation using an array type LREAL of 2 Dword, where the long real is coded using IEEE 754 format. The zip file attached contains the library, a FBD section to test the library and a tool allowing to convert the IEEE 754 format (useful to make the test) Be aware that all the controls are not performed when overflow happens, so use the library with care, mainly when you perform type conversions.

This knowledge base document do not intend to explain how to create a EPE supervision project but to give best practice advises on how to customize a EPE project based on General Purpose Library – GPL Situational Awareness. Software versions used in the kb: EcoStruxure Hybrid DCS 2019. GPL SA R2. This kb also apply to EcoStruxure Process Expert 2020 and further versions based on GPL SA. The GPL SA workspace include project is based on Citect Scada Situational Awareness template. The General Purpose Workspace leverage from Citect Scada Parameter Page Logo as show on the picture ... Keep reading this article to learn how to customize the GPL workspace with customer logo.

Issue The Modicon M580 Hot Standby System is a redundant control system designed for high availability and reliability in industrial applications. It consists of two M580 Programmable Automation Controllers (PACs) configured in a Hot Standby configuration, where one PAC operates as the active controller and the other as the standby controller. It is possible to have the other standby controller to run program sections while in Wait or Standby state. Resolution Any program sections of the application can be executed by defining the condition of execution in the Properties window of the Section screen under the Condition tab. Disclaimer The views and opinions expressed in this article are those of the author(s) and do not necessarily reflect the official policy or position of Schneider Electric.

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. Disclaimer The views and opinions expressed in this article are those of the author(s) and do not necessarily reflect the official policy or position of Schneider Electric.

Issue There are some scenarios where making online modifications on the standby CPU of a hot standby system may be necessary. For example, if there are changes to the process or system configuration that need to be implemented immediately, and the primary CPU is not available, making online modifications on the standby CPU may be necessary to ensure continuity of the process. Resolution To make online modifications to an application program, a logic mismatch signal will be enabled to allow a Hot Standby system to continue operating even if there is a mismatch between the applications in the Primary and Standby CPUs. The Logic Mismatch feature will be used to modify an application program and the I/O configuration while the process remains redundant. This document describes the procedure to perform an online modification to a Modicon M580 Standby controller.
