Programming Appendix A
Instructions Not Allowed in Subroutines
The following instructions cannot be placed in a subroutine.
Note Block Program Sections
A subroutine can include a block program section.
Instructions Not Allowed in Step Ladder Program Sections
Note A step ladder program section can be used in an interlock section (between IL(002) and ILC(003)). The
step ladder section will be completely reset when the interlock is ON.
Instructions Not Allowed in Block Program Sections
The following instructions cannot be placed in block program sections.
Note (1) Block programs can be used in a step ladder program section.
(2) A block program can be used in an interlock section (between IL(002) and ILC(003)). The block pro-
gram section will not be executed when the interlock is ON.
(3) A JUMP instruction (JMP(004)) can be used in a block program section, but the JUMP (JMP(004))
and JUMP END (JME(005)) instructions must be used in a pair within the block program section.
The program will not execute properly unless these instructions are paired.
