ISPSoft User Manual Open the window for RUN_STOP , and force STOP_BT ON. RUNNING is reset to OFF. The equipment stops running. Open the window for GLUING , and force InP_SNR_1 OFF. TRIG_1 is still ON. The situation is correct. RUNNING is a flag connected to the En pin of the function block. RUNNING is OFF, and therefore the function block is not executed. The value of TRIG , a pin of the function block, is not sent to the symbol TRIG_1 , and therefore the state of TRIG_1 remains unchanged. 7-46
