Approaches are also ideas, and the common programs we usually see can be summarized intotwo approaches.
1. Use coil outputs for output points, with only one occurrence in the program.
2. Directly control output points using set and reset, with one output point appearing multiple times in the program.
What approaches do you all use, and what are their respective advantages and disadvantages?/
Netizen A: I prefer the second approach; the first one is a bit cumbersome with manual switching, which increases the number of program steps. For example, when dealing with a single control solenoid valve, it automatically positions the cylinder. At this point, switching to manual control of that cylinder requires resetting the automatic state.
Netizen B: Generally, I use M points to control coils; multiple M points can control one coil in the program, which avoids multiple coils, similar to the first approach.
Netizen C: I lean towards the second approach; the first one is troublesome with all the switching.
Netizen D:
Approach one: one output corresponds to a set of logic, determining when this output point is turned on, turned off, alarmed, reset, or emergency stopped;
Approach two: set and reset, suitable for this program step, while outputting several at once.
For example, when you are about to go out, you need to take your phone, wallet, and car keys;
Approach one: when to take the phone, when not to take the phone;
Approach two: when the logic of going out is reached, I take the phone, wallet, and car keys.
