Objective The objective of this knowledge base article it to demonstrate how to disable the User Rights Only for the Web-visualization on M2xx controllers. Resolution This is done by creating an empty ".cfg" file on the controller files system and rebooting the controller. This helps accessing the visualization via the Web server without being asking for a password and username.

Issue When designing a Safety Instrumented Function (SIF), it is mandatory to define the Process Safety Time and ensure that the function will be executed within this time. According to IEC 61508, part 2, 7.4.3.2.5: The Process Safety Time (PST) is defined as the period between a failure occurring in the EUC (Equipment Under Control) or the EUC control system (with the potential to give rise to a hazardous event) and the occurrence of the hazardous event if the safety function is not performed. Resolution Engineers must carefully balance the scan cycle time and CPU bandwidth to ensure that all safety and non-safety tasks are executed efficiently. This often involves optimizing the program code and possibly upgrading hardware to meet the demands of stringent Process Safety Time (PST) requirements.

Issue The purpose of this document is to look at how and why devices using the Ethernet/IP protocol need to be managed at a switch level and how these simple settings can help improve system performance. Resolution Please review the document below.

Objective In this article, we will learn how to connect EAE HMI to a local SQL Database. The Database here emulates one that contains Recipes that are managed by an imaginary ERP system. We will learn C# Codes that leverages on existing .NET components to retrieve data from a Table which is then shown on the HMI.

Objective The Data Grid in EAE’s HMI is useful for many purposes. In this article, we will learn how to populate it with recipes so that the user may choose one to eventually send to a controller. Behind all of these are C# Codes. We will learn the codes and techniques necessary to perform the operations related. The eventual bigger picture is towards building a bigger application such as one that retrieves information from a data source. But before we can do that, we need to know the basics of Data Grid first.

Issue Teams with multiple engineers involved in authentication wants to use the Security Editor to administer access to EcoStruxure Control Expert (Classic & Topology Manager) software. The software tool simplifies the configuration of EcoStruxure Control Expert user access control and supports a secure centralized architecture. Resolution A centralized user management system reduces operational complexities in controlling user accounts and server requests. It enhances security by efficiently managing user requests for applications and online servers. Centralized user management improves security, simplifies administration, ensures compliance, and supports efficient operations in industrial settings. EcoStruxure Control expert Client-Server Architecture This document aims to provide you with recommendations for configuring an EcoStruxure Control Expert (Classic & Topology Manager) in a secure client-server architecture. 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 Teams with several engineers want to be able to gain access to the EcoStruxure Control Expert Classic software through authentication. In addition, the tool facilitates user access control configuration for EcoStruxure Control Expert Classic software and allows a secure centralized network design. Centralized Security Database Resolution The Security Editor tool simplifies the configuration of EcoStruxure Control Expert Classic user access control and supports a secure, centralized architecture with the following features: Client-server architecture supporting a secure proprietary protocol for users without IT authentication infrastructure. Client-server architecture using the Microsoft Active Directory as the Lightweight Directory Access Protocol (LDAP) server. Manage the certificate whitelist. Generate a certificate. Centralized security database.

Objective The purpose of this article is to introduce the necessary steps to calibrate a Lexium Multicarrier track with the example project embedded in EcoStruxure Machine Expert. Resolution This article has highlighted how to calibrate a Lexium Multicarrier track in EcoStruxure Machine Expert. It shows which steps must be done and guides the reader through the functionalities and provided structure of the track calibration.

Issue I would like to upgrade the firmware of my Modicon Switch to overcome published vulnerabilities identified in the previous firmware version or gain access to features delivered in a newer Resolution The aim of this article is to provide a step-by-step guide to update the firmware of Modicon Managed Switch using the Web Interface. 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 Programming explicit requests in EcoStruxure Control Expert requires care to ensure they execute correctly. Resolution The attached document explains how to program blocks, like READ_VAR and WRITE_VAR using a technique known as a State Machine. 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 When building a Solution in EAE, each engineer has their own idea of how to name items such as pins on a function block, the names of Composite or Basic Function Blocks which they create, the names of folders, Symbols, Faceplates and the list goes on. Without a standard naming convention to conform to, a Solution can become an accumulation of unorderly syntaxes. Resolution This article serves to uncover the different naming conventions widely used in real world engineering. A EAE Naming Convention Reference Card is also provided. Its intention is to be used as a guide during your EAE’s engineering lifecycle. It is produced based on close observation of Schneider’s Libraries that comes in EAE.
