The APAX-5620 PLC now supports redundancy. When the primary controller goes offline, in less than 10 ms, the backup controller will take over. Programmers can configure the primary and backup controller from a simple configuration screen; no code-level thinking is required. The product supports five IEC-61131-3 languages, including ladder diagram, function block diagram, structured text, instruction list, and sequential function chart. Programmers can develop a project in any of these languages or combination of languages, allowing them to take advantage of each language’s key feature.
