Appendix I Programming Considerations
When using the ladder programming language, to avoid many of the same variable operation
with the same instruction. Scan sequence ladder program, the program is from top to bottom, left
to right. When programming, do not copy and paste commands in the editing area (function
blocks), or compiler errors, you can drag the editing area from the right side of the Edit wizard, or
type the command (function blocks) name directly in the editing area.
The following command does not support:
GET_CHAR
GET_ERROR
GET_ERROR CATALOG
GET_SYM
CLR_OUT
COLD_RESTART
CONTINUE
HO_ RESTART
WRITE_RETAIN
WARM_RESTART
Written instructions PDD variables, such as WR_BOOL_BY_SYMFOR cycle: the number of
steps can not be too long, such as 15,000, or may error, a program can not be more larger the FOR
loop (such as 10,000 steps) appears, or it may be wrong. The maximum length of the array
ARRAY is 32767.
