Introduction
Links connect steps and transitions, transitions and steps, etc.
Attention should be paid to the following programming information:
Links between objects of the same type (step with step, transition with transition, etc.) are not possible.
Links are possible between:
Unused object outputs
Used or unused step inputs
(i.e. step inputs can be connected using links)
Overlapping links and other SFC objects (step, transition, jump, etc.) is not possible.
Overlapping links and links is possible.
Crossing links and links is possible. Crossed links are indicated by a "broken" link.
The signal flow is generally from top to bottom. In exceptional cases (e.g. return) it can also be from bottom to top. This special case is indicated using an arrow symbol.
