Chapter 1 Introduction 13. Hot swap The AH500 series I/O modules support the on-line uninterruptible hot swap. When the system runs, users can replace the module which breaks down without disconnecting the module. After the module is replaced, the new module runs normally. Users do not need to set the module manually or switch the state. 14. Supporting the on-line debugging mode After a single instruction step has been complete, or after a breakpoint is specified, users can easily find the bug in the program by means of the on-line debugging mode supported by the AH500 series CPU module. If users want to enter the debugging mode, the CPU module must run.
After users enable the on-line . The debugging screen varies from programming language to programming language, but the same operation applies to these programming languages. For the AH500 series PLC, structured texts do not support the debugging mode, and sequential function charts support the debugging mode during the action and the transition. Step 1: Setting the PLC to RUN monitoring function, they have to click 1-15
