some changes means like downloading blocks into plc. Is it possible to change plc user program and download to plc without stopping plc

In V11 SP2, some changes are allowed which do not require plc stop. However, modifying DBs, adding OBs/FBs/FCs often require a plc stop.

"You can make the following changes in program blocks and tags and download them in RUN mode:

• Create, overwrite, and delete Functions (FC), Function Blocks (FB), and Tag tables.

• Create and delete Data Blocks (DB); however, DB structure changes cannot be overwritten. Initial DB values can be overwritten. You cannot download a web server DB (control or fragment) in RUN mode.

• Overwrite Organization Blocks (OB); however, you cannot create or delete OBs.

A maximum number of ten blocks can be downloaded in RUN mode at one time. If more than ten blocks are downloaded, the CPU must be placed into STOP mode.

Once a download is initiated, you cannot perform other tasks in STEP7 until the download is complete."

Dear Ganes10,
The points which you have mentioned are all correct, however there are limitations in the number of chages you can make in each FB,FC or OB before downloading.
