Separation of flow
When creating an SFC program having two or more initial state relays, separate the blocks for each initial state relay.
The ON status can be transferred among SFC programs created by block separation (jump to a different flow).
A state relay in a program created in a different block can be used as a contact for the internal circuit or transfer condition of
another state relay.
