What does FCS0101 SFCSWDAC SF-0001 S=2(0) L=1 100-81C1 mean in the system alerts? In SFCSWDAC, DAC is the material code

There is a problem with the SEBOL statement used in your SFC. S=2 is the step number, and L=1 is the first line of the SEBOL statement. Find this statement and see what the reason is. This is a non-fatal error. For example, operations like dividing by 0.

May I ask, does this alarm mean that the sequential control program will not proceed to the next step?

Hello: This controller is used to regulate the amount of feed in kilograms. There is a problem now: after the button is pressed, it does not stop automatically once the set value is reached. This alarm appeared right after it started. Modules such as ST16, _SFCSW, TM, and BDSET-1L are used in this. Is it this alarm that is causing the program to malfunction?
