jwlamb Posted September 11, 2015 Share Posted September 11, 2015 I am trying to download a simple PLC (attached) into a Geo Brick LV. The code before the OPEN seems to do what is expected, but once the OPEN has been issued, the following lines give an error: **PMAC Error 5, Command not allowed unless buffer is open I am downloading through PEWIN32Pro2 v4.4.0.0, and have stopped all PLCs. Any help on this would be appreciated.read-positions-v1.txt Link to comment Share on other sites More sharing options...
jwlamb Posted September 11, 2015 Author Share Posted September 11, 2015 OK, please ignore. I had a typo in my variable names and the #define'd names had a case difference relative to the invoked names :-( Works as expected now :-) Link to comment Share on other sites More sharing options...
