Refer to my recent post /tf/WW/en/Posts/55504#top At the first OB's first network, turn off a BIT, call it "RUN MODE" At the last OB's last network, turn onthat RUN MODE BIT. Process image updates to always set the RUN MODE BIT to ON. If the PLC fails after the RUN MODE BIT is set to OFF (program crash), the process image seems to still be updated, so it would beset to OFF. You can use a counterthatincrements everyscan. If the counter stops, so has the CPU. |
