Issue There are often customer requirements to send safety related data over communications links. At the same time, the requirement automatically arises for the transference of safe and non-safe data via a collective standard network. A safe network will allow the Safety controller to communicate with each other and provides a robust and safe means of sending safety related data using the communications medium that best suits the applications and budget. Resolution With M580 Safety CPU firmware 3.20 or later, the safe time synchronization is based on an internal "monotonic" time clock. The safe communication DOES NOT need NTP time synchronization as the CPU is sharing its safe time with all its local and remote I/Os. The remote I/O drop uses BM•CRA31210 module and must have a firmware 2.60 or later to work. A monotonic clock is a time source that always moves forward and will not be impacted by variations leading to jumps in time (due to NTP or Daylight Savings Time updates). Monotonic uses Thomas Habets's cross platform "monotonic_clock" library under the hood. Attached herewith are two documents file that guide you on how to implement Safe Peer-to-Peer communication between two M580 Safety ePAC (MASTER PAC and SLAVE PAC).

Issue In some network architectures, the transparency of the network is necessary to be able to do configuration and commissioning from a local engineering station without having to go to the field, reducing the time of downtime and commissioning. Resolution This document explains the configuration of the BMENOC0321 Network Card to obtain transparency in the network without the need for the use of L3 switches.

Issue When connecting Schneider controllers to a customer network infrastructure there is often an issue where the path between IT and OT seems blocked. The purpose of this document is to examine one of the common causes and explain the different architecture philosophy implemented in IT using Cisco as an example. Resolution Please the attachment for more details.

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 If the Local Network Interface is not configured, the connection to the Harmony HMIBSC Edge Box will be not established. Resolution This article describes the necessary steps how to configure the Local Network Interface on HMIBSC Edge Box.

Issue In a M580 Hot Standby architecture the BMENUA0100 Module does not swap IP addresses like the other communication modules, therefore the SCADA system has to independently detect which NUA module is Primary. Resolution The aim of this document is to provide a step-by-step guide for configuration of AVEVA Plant SCADA (Citect) communicating to the BMENUA0100 Module using OPC UA Client and M580 Hot Standby.

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 Dynsim provides the full power of rigorous dynamic simulation and high-fidelity control system emulation for process engineers, control engineers, plant operators, and plant managers to optimize plant design and operation. AVEVA APC provides the integrated capability to develop, implement, and support model-predictive control and optimization strategies. These strategies tighten the control of the key variables in a process and push the process as a whole closer to the economic optimum. Resolution This workshop steps through the usage of these offers, See the attachment for all the details.
