Issue There are some scenarios where making online modifications on the standby CPU of a hot standby system may be necessary. For example, if there are changes to the process or system configuration that need to be implemented immediately, and the primary CPU is not available, making online modifications on the standby CPU may be necessary to ensure continuity of the process. Resolution To make online modifications to an application program, a logic mismatch signal will be enabled to allow a Hot Standby system to continue operating even if there is a mismatch between the applications in the Primary and Standby CPUs. The Logic Mismatch feature will be used to modify an application program and the I/O configuration while the process remains redundant. This document describes the procedure to perform an online modification to a Modicon M580 Standby controller.

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.
