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.   Function list Math functions ADD_DREAL SUB_DREAL MUL_DREAL DIV_DREAL ABS_DREAL NEG_DREAL POW_DREAL SQRT_DREAL EXP_DREAL LN_DREAL LOG_DREAL Trigononmetric Functions ACOS_DREAL ASIN_DREAL ATAN_DREAL COS_DREAL SIN_DREAL TAN_DREAL Logic Functions EQ_DREAL GE_DREAL GT_DREAL LE_DREAL LT_DREAL Convertion Functions INT_TO_DREAL DINT_TO_DREAL DREAL_TO_DINT DREAL_TO_INT DREAL_TO_REAL DREAL_TO_STRING REAL_TO_DREAL 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.

Introduction The attached document explains the best practice of implementation of FDT/ DTM technologies for integration of smart instruments (HART supported instrumentations) into Automation system architecture Exercise In the exercise, it will have some specific customer requirements scenario. By the completion of this lab the participant will be able to: • To design and to decide the correct place/ platform to implement FDT/DTM in order to answer specific customer requirements in their whole life cycle of the project (engineering/development, commissioning, maintenance and operation • To understand the drawback or limitation for each platform in term of FDT/DTM implementation in order to help participant to decide the correct platform.

Issue One of the biggest challenges in the industrial automation and control field is how to get machines to talk to each other. Exchanging data from machine to machine, or a machine to PC, machine integration between vendors of different types can be complex, laborious, and difficult, requiring expensive engineers and incurring significant expense. When you integrate systems of multiple vendors to provide total solutions to your customers, you want to use standardized, reliable, secure, scalable and platform independent technology. Resolution This is where we can leverage the OPC UA (Open Platform Communications Unified Architecture) to solve these strategic issues faced by most manufacturers. It is a standardized protocol that allows for seamless and secure communication between different systems and devices, regardless of the vendor or platform. The document here describes one of the methods of exchanging data between different machines. By implementing OPC UA client function blocks in a controller, the controller can directly access data from any other OPC UA servers. As an example, a demo architecture is shown: A virtual machine or PC is used here as the OPC-UA server and the Modicon M580 ePAC as the OPC UA client, should be on the same network and should have the correct network settings configured. The virtual machine's network adapter should be set to bridged mode, and the virtual machine PC's firewall settings should allow communication with the M580 CPU (Firmware ≥ 4.10). See attached document on how to implement the Modicon M580 OPC-UA Client Read/Write function blocks.

Issue The IEC 61131-3 not only describes the PLC programming languages themselves, but also offers comprehensive concepts and guidelines for creating PLC projects. Defined in IEC 61131 standard, a Program Organization Unit (POU) provides a modular and hierarchical way of structuring programs that makes it easier to develop, debug, and maintain industrial control programs. How will this concept be used to organize and structure industrial control programs? Resolution In this document the term POU is used for programming elements in general that can contain IEC code, such as methods, properties, interfaces etc. The term Program Organization Unit (POU) is used for all programming objects (programs, function blocks, functions, etc.) which are used to create a controller application.   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.
