Real-Time Vista Basic Commands - ABB PGC2000 Operation And Service Manual

Real-Time Vista BASIC Commands

While all standard Vista BASIC commands are available for use with Real-Time Vista BASIC, the
following commands are specifically for running in real time.
When using Real-Time Vista BASIC, do not use these commands: LPRINT and
DACS_EVT_MSG!
The Real-Time Vista BASIC program can generate LPRINT and DACS_EVT_MSG information
FASTER than it can be processed. This could eat up all of the memory in the GCC.
