Appendix B
Programming Instructions
This appendix provides tables listing the programming instructions used with C200H PCs. The first table sum-
marizes all instructions and gives page references where more detailed information can be found in the body
of the manual. The second table gives the execution times for the instructions for both ON and OFF execution
conditions. The third part is divided into two tables and summarizes the instructions, giving the ladder diagram
symbol, a brief description, and the applicable data areas. In all tables, the entries are listed alphanumerically.
Instructions without function codes are given first in alphabetical order, according to the mnemonic. These are
followed by the instructions with function codes which are listed numerically, according to the function code.
A PC instruction is entered either using the appropriate Programming Console key(s) (e.g., LD, AND, OR,
NOT), or by using function codes. To input an instruction using its function code, press FUN, the function
code, and then WRITE.
