Follow the ISA-88 standard for batching. Break your operation into phases and follow the state model (Idle/Active/Held/ect...) to control equipment. Have a permissive check before transitioning to active, and program faults that will force the phase to be held. Equipment only runs when the right phase is active.
Rockwell has something in ControlLogix called Phase Manager that does a lot of the work for you when it comes to controlling phases, but it's not too hard to program your own phase state engine once you understand the model.

Try reading the "Ice Cream" book, Applying S88: Batch Control from a User's Perspective. It was recommended to me from a colleague who worked at Emerson (who developed DeltaV) as a standard introduction to S88 methodology and control implementation.

Fun fact, DeltaV's hierarchy is laid out using S88 as a basis for the entire program. It is very well laid out in terms of the top down approach S88 suggests. It gives layout suggestions and rules of thumb in equipment organization for scheduling, acquiring, and releasing certain pieces of equipment for the batch's recipe. DeltaV is made for this stuff.
You may also hear about Honeywell Experion's Batch manager (which is total garbage in my professional opinion). It's really only used as a means to quickly migrate legacy Honeywell batch code. You can do the same stuff in their application control environment (ACE) node with recipe control modules and sequential control modules but it's not as well laid out in terms of program hierarchy as DeltaV.
Siemens also has a robust batch program but I'm not too familiar with it.
Have fun though with this type of stuff! Once you get the process vetted and approved with minimal downtime, optimal batch executions and robust troubleshooting/fault handling, it really pays off and feels like you've made a difference. Good Luck!
