SET // Set RLO to 1SAVE// Save RLO to BR bit ~ ~ When BR= 1, the output of ENO is 1, so please use it with caution, because ENO also indicates the execution status of FB and FC. If forced to 1, then you need to program FB and FC separately. Otherwise, it will cause program defects ~ ~ In addition, it is not necessary to use ENO to trigger the subsequent FB, and users can use FC's Return and FB's OUT variables to trigger the execution of subsequent blocks. exceed
