Programming Appendix A
Instruction Location and Input Conditions
The following table shows the possible locations for instructions. Instructions are grouped into those that do
and those do not require input conditions.
Note (1) There is another group of instructions that executes a series of mnemonic instructions based on a
single input. These are called block programming instructions. Refer to the Instructions Reference
Manual (Cat. No. O011) for details on these block programs.
(2) If an instruction requiring an input condition is connected directly to the left bus bar without a logical
start instruction, a program error will occur when checking the program on the CX-Programmer.
Addressing I/O Memory Areas
Bit Addresses
Example: The address of bit 03 in word 0001 in the CIO Area would be as shown below. This address is given
as “CIO 0001.03” in this manual.
Word Addresses
Example: The address of bits 00 to 15 in word 0010 in the CIO Area would be as shown below. This address
is given as “CIO 0010” in this manual.
