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 When an EcoStruxure Process Expert application is being created, the user groups need to be planned according to the actions allowed to each one of them on the supervision participant Resolution This document explains how you can plan your users groups based on the Classic GPL.

In 2019 EcoStruxure Process Expert was released with a new General Purpose Library for Situational Awareness – GPL SA - as its default library. This is a new library and while functionally like previous General Purpose Library – GPL Classic - there is no direct upgrade between the libraries. Instead the existing library is maintained and supported for existing customers. If projects or customers want to leverage the new general process library, they must migrate their project between the libraries and re-draw their graphics screens...

Issue Schneider Electric provides M580 ePAC and Ethernet modules. Several architectures are already documented. However, the need of customer sometimes is different and requires a specific architecture. In this case, we will have a look on remarks and questions regarding topology and modules characteristics with a special focus to avoid broadcast storms. Resolution From extraction of the EcoStruxure Control Expert Help and “M580 Ethernet Remote IO / Distributed IO Principles and Technologies” document, this article reminds the basic rules of the Ethernet ports of modules and Ethernet cables to connect or not, to avoid broadcast storm.

All control projects require some level of time synchronization. The time synchronization serves a fundamental role in any network, but it's too often added as an afterthought. However, it can mean the difference between correctly troubleshooting in minutes and returning the production to the desired level or having no idea about what caused production lost. The Network Time Protocol is a client-server protocol and has been widely adopted in all kind of Industries since 1985. It is a low-cost solution that can be easily applied for all EcoStruxure Process Expert architectures.

How to Enable Native Citect Scada OPC DA Server on EcoStruxure Process Expert? In EcoStruxure Process Expert 2019 (former HDCS) and previous versions the communication between the supervision participant Citect Scada and Modicon PAC controllers are handle by OFS – OPC Factory Server. The OFS is an OPC DA Server which is installed in the same server as the EPE operation server(s). Whenever a third-party software needs to collect data from EPE it can be done by connecting to OFS Server in either primary or standby operation server. This solution using OFS Server as an unique OPC DA Server to interface with other system works fine but some customers standard or customers best practice doesn’t allow other systems to collect data direct from the controllers. These customers prefer third-party software collecting data from the supervision servers. Another motivating force to have an OPC DA server enabled on supervision participant is that some projects could have calculate variables on supervision which does not exist on control project...

Issue Once a Modicon Edge I/O NTS distributed system is configured using the configurator or the web interface, the next step is to download the configuration into the target hardware. At this stage, there may be input/output modules that are part of the detected hardware using an older firmware version that is not compatible. To overcome this configuration mismatch, an update of the firmware of the existing modules is required. Resolution The purpose of this article is to show how to perform bulk firmware update for input/output modules that are part of a Modicon Edge I/O NTS island using EcoStruxure Automation Device Maintenance.

Issue Explicit messaging can be used more effectively instead of implicit messaging in a few use cases. E.g. polling multiple services devices connected through a Modbus TCP to serial gateway; or configuring event-based read/write communication instead of cyclic ones. EcoStruxure Control Expert provides many function blocks for explicit messaging. The Data_Exch block stands out as it allows to program any Modbus or Ethernet/IP query required by the users. However, from its user manual, it's not so clear on how to go about it. Resolution This article can be read as additional guidance to users apart from the block's user manual. Focus is on using this block for any Modbus query, and as an example, Function codes 22 and 23 are implemented. Usage of Data_Exch over Ethernet/IP is not included as it has been well described in an existing document.

Introduction The GPL Communication library contains objects managing explicit messaging for Modbus TCP and Modbus RTU technologies. This document will summarize how to manage devices on serial lines connected to BMXNOM0200 module on M580 X80 drops on EcoStruxure Process Expert/ Hybrid DCS platform Resolution Please see attached document where it explains how to manage devices on serial lines connected to BMXNOM0200 on M580 drops on EcoStruxure Process Expert/ Hybrid DCS platform.
