Hi guyz,

My $1 question to all the gurus.

In siemens step7 we can download FC or FB(with DB) without downloading the whole program which give programmer ease to work away from the control panels and download once finished without stopping the process or PLCs.

But in RSLogix5000 or Unity Pro XL i failed to find that option. you need to be online and then build/verify to do the changes. which makes difficult for the programmer and require presence at the control panels.

How we can achieve the same option as Siemens in RS Logix5000 or Unity Pro XL softwares.

cheers

Unity Pro... if a used developed DFB has been added to the "custom" libray then it can be "added" to a project database while on-line and in run.

If the DFB is not currently in the library...

1. Online/run/equal.

2. Detach from Controller and close the current project.

3. Open a project containing the desired DFB or develop/test a new DFB.

4. Add the desired DFB to the Unity library.

5. Close this project.

6. Open the original project and connect (online/run/equal).

7. Browse to the Derived FB Types folder

8. Select "Get from Library" and proceed.

9. Build changes (no controller stop).

DFBs may also be developed and modified while on-line and in run. DFBs can be protected against changes (or examination) using passwords.
