SECTION 5
Instruction Set
The C200HX/HG/HE PCs have large programming instruction sets that allow for easy programming of complicated control
processes. This section explains instructions individually and provides the ladder diagram symbol, data areas, and flags used
with each.
The C200HX/HG/HS PCs can process more than 100 instructions that require function codes, but only 100 function codes (00
to 99) are available. Some instructions, called expansion instructions, do not have fixed function codes and must be assigned
function codes from the 18 function codes set aside for expansion instructions before they can be used.
The many instructions provided by the C200HX/HG/HE PCs are organized in the following subsections by instruction group.
These groups include Ladder Diagram Instructions, Bit Control Instructions, Timer and Counter Instructions, Data Shifting
Instructions, Data Movement Instructions, Data Comparison Instructions, Data Conversion Instructions, BCD Calculation
Instructions, Binary Calculation Instructions, Logic Instructions, Subroutines, Special Instructions, Network Instructions,
Serial Communications Instructions, Advanced I/O Instructions, and Special I/O Unit Instructions.
Some instructions, such as Timer and Counter instructions, are used to control execution of other instructions, e.g., a TIM
Completion Flag might be used to turn ON a bit when the time period set for the timer has expired. Although these other
instructions are often used to control output bits through the Output instruction, they can be used to control execution of other
instructions as well. The Output instructions used in examples in this manual can therefore generally be replaced by other
instructions to modify the program for specific applications other than controlling output bits directly.
