The Omron CP1H series of programmable logic controllers are capable of having 4096 basic counters. There are two basic counter instructions in the PLC. Each of the basic instructions can be either binary or BCD. The memory area for counters has separate areas for the Counter PVs (Present values) and the Counter Completion Flags. We will be looking at the basic Counter instructions in the CP1H along with some programming examples.
The secret to using counters is a post that will go over timing charts. It is a good place to understand how timing charts can assist you in programming counters.

There are several reasons why we are using the Omron CP1H Controller. Here are just a few.
- Standalone PLC with built-in I/O
- Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus, Host Link, ASCII (No Protocol)
- Built-in Analog inputs and outputs
- 4 axis control of motion
- 4 high-speed counters
- powerful instruction set (similar to CS and CJ series)
- Ability to expand the system with a variety of modules
The Omron CP1 series of programmable logic controllers consists of three different units. CP1E is the cost-effective unit, CP1L is the high performing controller that can come with embedded Ethernet and the CP1H is the position control and comprehensive programmable logic controller.
We will be looking a the CP1H for this series, but a majority of the information can be applied to the CP1E and the CP1L controllers as well.
