Page 12: About This Manual
The CP Series is centered around the CP1H CPU Units and is designed with the same basic architec- ture as the CS and CJ Series. The Special I/O Units and CPU Bus Units of the CJ Series can thus be used.
Page 13 Section 4 describes the structure and functions of the I/O Memory Areas and Parameter Areas. Section 5 describes the CP1H’s interrupt and high-speed counter functions. Section 6 describes all of the advanced functions of the CP1H that can be used to achieve specific application needs.

Page 21: Intended Audience
!WARNING It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
Page 22 As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system. • The PLC or outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.
Page 23: Operating Environment Precautions
• Locations subject to possible exposure to radioactivity. • Locations close to power supplies. !Caution The operating environment of the PLC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System.
Page 24: Application Precautions
• Connecting or disconnecting the connectors !Caution Failure to abide by the following precautions could lead to faulty operation of the PLC or the system, or could damage the PLC or PLC Units. Always heed these precautions. • Install external breakers and take other safety measures against short-cir- cuiting in external wiring.
Page 25 Doing either of these may break the cables. • Do not place objects on top of the cables. Doing so may break the cables. • When replacing parts, be sure to confirm that the rating of a new part is correct.
Page 26 • If the I/O Hold Bit is turned ON, the outputs from the PLC will not be turned OFF and will maintain their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM mode.
Page 27: Conformance To Ec Directives
EMC Directives OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note).
Page 28: Relay Output Noise Reduction Methods
The CP1H PLCs conforms to the Common Emission Standards (EN61131-2) of the EMC Directives. However, noise generated by relay output switching may not satisfy these Standards. In such a case, a noise filter must be con- nected to the load side or other appropriate countermeasures must be pro- vided external to the PLC.

Page 33: Features And Main Functions
The SYSMAC CP1H is an advanced high-speed, package-type Programma- ble Controller. While the CP1H employs the same architecture as the CS/CJ Series and provides the same I/O capacity of 40 I/O points as the CPM2A, the CP1H is approximately ten times faster.
Page 34 • The CPU Unit has 4 analog voltage/current inputs and 2 analog voltage/ current outputs built in. • The CP1H can be expanded to a maximum total of 320 I/O points by using CPM1A Expansion I/O Units. • Using CPM1A Expansion Units also allows extra functions (such as tem- perature sensor inputs) to be added.

Page 69: Function Blocks
Function blocks allow complex programming units to be reused easily. Once standard program sections have been created as function blocks and saved in files, they can be reused just by placing a function block in a program and set- ting the parameters for the function block's I/O. Reusing standardized function blocks reduces the time required for programming/debugging, reduces coding errors, and makes programs easier to understand.

When pulse output ports 2 and 3 are used, the cycle time increases in propor- tion to the output frequency. Cycle time rate of increase (%) from pulse output ports 2 and 3 = Output fre- quency (kHz) 0.1.
Page 127: Online Editing Cycle Time Extension
Online Editing Cycle Time Extension When online editing is executed to change the program from the CX-Program- mer while the CPU Unit is operating in MONITOR mode, the CPU Unit will momentarily suspend operation while the program is being changed. The period of time that the cycle time is extended is determined by the following conditions.
Page 128: I/O Response Time
The I/O response time is the time it takes from when an input turns ON, the data is recognized by the CPU Unit, and the user program is executed, up to the time for the result to be output to an output terminal. The length of the I/O response time depends on the following conditions.

The SRCH(181), MAX(182), and MIN(183) instructions can output the PLC memory address of the word with the desired value (search value, maximum, or minimum) to IR0. In this case, IR0 can be used in later instructions to access the contents of that word.
Page 201 If, for example, instruction A above is a comparison instruction, table data could be read from start to the end of the table to compare all of the data with a specific value. In this way, blocks of user-defined processing can be freely created depending by applying Index Registers.
Page 202: Precautions For Using Index Registers
Each Index Register task is processed independently, so they do not affect each other. For example, IR0 used in Task 1 and IR0 used in Task 2 are differ- ent. Consequently, each Index Register task has 16 Index Registers.
Page 203 FINS commands, write a program to store Index Register values from each task to another area (e.g., DM area) at the end of each task, and to read Index Register values from the storage words (e.g., DM area) at the beginning of each task.

Page 223: Scheduled Interrupts
Section 5-1 Interrupt Functions When CIO 0.01 goes from OFF to ON 200 times, processing of the cyclic task that is currently being executed will be interrupted and processing of interrupt task 141 will start. When the interrupt task processing is completed, process- ing of the interrupted ladder program will restart.
Page 224 Scheduled Interrupt Interval Setting Note (1) Set a scheduled interrupt time (interval) that is longer than the time re- quired to execute the corresponding interrupt task. (2) If the scheduled time interval is too short, the scheduled interrupt task will be executed too frequently, which may cause a long cycle time and ad- versely affect the cyclic task processing.

Origin Search The ORG instruction outputs pulses to turn the motor according to the pat- tern specified in the origin search parameters.
Page 281 The origin location can be determined after using either method. The CP1H CPU Units are also equipped with the origin return function, which can be executed to return the system to the origin after the origin location has been determined by one of the methods above.

These set- tings affect all pulse outputs. (This setting is called the Limited Input Signal Operation setting.)

Set a Origin Proximity Input Signal dog setting that is long enough (longer than the deceleration time.)
