That's a bit scary.  We have had some problems with interlocks in seq
code.  It has to be done with care and is a difficult thing to accomplish
correctly.  We are moving away from having interlocks solely in seq
code (they must be duplicated in other cont. blocks and/or a separate
PLC).  Be very careful with this.
