Issue When reading a string from the logic and displaying it in EcoStruxure Automation Expert, sometimes the user needs to change it from the HMI, it is not natively possible using drag & drop whilst creating a CAT. Resolution This knowledge base will show how to customize and do the C# code to not only read the string from the input, but to allow you to change the string from the HMI and update the output.

Objective In this KB, we will learn the basics of how to create our own button symbol that can be mapped to a physical digital output. This technique is based on leveraging inbuilt available objects. The knowledge gained will enable us to further develop our own animated symbols using other available graphic objects in the Canvas Designer.

Issue References are widely used in programming, especially to efficiently pass large or mutable data as arguments to procedures, or to share such data among various uses. A reference may point to a variable or record that contains references to other data. This idea is the basis of indirect addressing and of many linked data structures, such as linked lists. Resolution There are many advantages of using variables reference over pointer variables (like in C++ programming) such as: A reference variable does not consume any extra memory. It has the same memory address as the variable it refers to. While a pointer needs extra space for itself. In order to access the value of the referenced variable using pointer, we need to use a dereferencing operator whereas we can do the same using reference variable without any dereferencing method. Reference variables are cleaner and modish as compared to the pointers; they can also be used while passing in the function as arguments, known as call by references.

Issue How can I configure Plant SCADA to communicate with the Modicon M580 BME NUA 0100 (OPC UA) module using trusted certificates. Resolution The attached document provides a step-by-step guide for the configuration of AVEVA Plant SCADA (Citect) communicating to the BMENUA0100 module using OPC UA Client and Trusted Certificates.

Issue Customers would like to monitor the power supply modules of the Modicon M580 controller and observe whether they function correctly. Diagnose and analyse with the information so as to find its root cause. Resolution The Modicon X80 Redundant Power Supply module beside providing power supply module redundancy coming from different power sources, it can also provide users monitoring and diagnostics information. The PWS_DIAG and PWS_CMD function function blocks provide users internal diagnostic (e.g. voltage and current) for each of the redundant power supply modules.

Issue Using the GroupManagement/GroupControl objects to configure group/subgroup route & sequences – EPE 2021 Resolution This document will help you understand and use the $GroupMGTGP/$GroupCTLGP objects to quickly configure start/stop sequences of assets, routes and also generate subgroups that are part of the main sequence. These objects are part of the “Group Control Library”.

Background There are some industry segments (such as power) which require that when communication with RTU/PAC/PLC is broken, instead of showing the #BAD #COM or #PEND, display the last know good value instead. Resolution In this sample project, we show how to make use of Tag Extension for such matters.

Issue How to migrate previous version of EcoStruxure™ Control Expert Classic project to use in Topology Manager? The functionality of Topology Manager within EcoStruxure™ Control Expert provides a collaborative environment that manages, designs and deploys the entire automation architecture with multiple controller systems including various types of automation assets. Resolution To convert and upgrade existing EcoStruxure™ Control Expert Classic project to the latest version of EcoStruxure™ Control Expert Classic, at least from version 15.1 onwards. Create a new System Project and import the converted or upgraded project into Topology Manager. To support the Topology Manager features, the I/O Scanning mode will be changed to Enhanced mode and the M580 CPU firmware must be at least version 2.70 or higher..

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 This document intends to give an overview on EcoStruxure CIP Advisor. It should cover the basic steps so a new user can start using and understanding better the EcoStruxure CIP Advisor.
