YASNAC PCNC PLC Programming Manual Chapter 4: Sequence Control Method
(5) Time Check
• The compiler checks the range of registers used for timers.
• It also checks the interference in the addresses of the timers (#1700s and #1300s).
(6) Label Check
• The compiler checks the ADR label names for overlapped definition.
• The correspondence between the JMP and ADR is also cheeked.
(7) STR and AND-STR Check
The compiler checks the correspondence between the STR (STR-NOT) and AND-STR
(OR-STR)
(8) SUBP Calling Sequence Check
• The compiler checks the correspondence between the SUBP and PUSH (APSH,
TPSH, IPSHD).
• It also checks the correspondence between the SUBP and STR.
(9) Existence Check for RTH and RET
The compiler checks the RTH and RET for the following:
• Only one RTH exists.
• Either RET or RTI exists.
