Hello suresh; Please verify if you present system meets the hardware/software requirements for CiR (Confguration in Run), which is what Siemens calls the hot-swapping method it applies.They is described in this manual: SIMATIC STEP7 V5.5 Modifying the System during Operation via CiR In particular (extracted from the introduction to that manual): To enable CiR, the user program must meet the following requirements: The program may not include elements that switch the CPU into STOP mode in the event, for example, of a station failure or module error. The following OBs have to be on your CPU: • Hardware interrupt OBs (OB 40 to OB 47) • Timeout OB (OB 80) • Diagnostics interrupt OB (OB 82) • Removal/Insertion OB (OB 83) • Program runtime error OB (OB 85) • Module rack error OB (OB 86) • I/O access error OB (OB 122) Hope this helps, Daniel Chartier |
