This might take the form of a separate NML channel or something - I don't know what would be the best design. In any case, you would use some program other than a "normal" EMC2 GUI to make changes through this new interface.

Pausing a program remains in AUTO mode, so doing any manual/MDI actions at that time is not possible with the current implementation. It may be possible to change the EMC2 modes around, or eliminate them altogether. This is a task for 2.4 or beyond, if it's to be done at all. - Steve ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
