About the trace variable！ #7

This problems is about the BEREMIZ runtime debug functions. If there are many vairables in a PLC program. such as 1000 DINT datas. each cycle the PLC must make 4000 bytes debug-buffer and each get-variable command will send 4000 bytes. Is it right?

No. Only registered (watched) variables are transfered the during debug session.

See RegisterDebugVariable and ResetDebugVariables functions in plc_debug.c template in targets subdir of beremiz dir.
