SECTION 5
Instruction Set
The C200HS PC has a large programming instruction set that allows 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 C200HS 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 C200HS 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, and Network 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.
