Switch Sequence Chain

A sequence chain is a procedure of multiple logic tables. At any time on step will be active only.

All steps of a sequence chain need to be in the same group.

The step number will be defined in the logic table header. Additional a step need to be defined as a member of a sequence chain.

Elements in the same group which are not part of the sequence chain are handled as normal logic tables.

The switching to another step sets the active sequence chain member to the given step. A step number can set directly, or it can be taken from a variable.

In case of switching to invalid step numbers - the destination step does not exist - the actual step number will be preserved. The OK bit will not be set.
