Page 24: 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 25 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 26: Operating Environment Precautions
!Caution When connecting the PLC to a computer or other peripheral device, either ground the 0 V side of the external power supply or do not ground the external power supply at all. Otherwise the external power supply may be shorted depending on the connection methods of the peripheral device.
Page 27: Application 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 28 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 29 • Wire correctly according to specified procedures. • Do not connect pin 6 (+5V) on the RS-232C Option Board on the CPU Unit to any external device other than the NT-AL001 or CJ1W-CIF11 Con- version Adapter. The external device and the CPU Unit may be damaged.
Page 30: Conformance To Ec Directives
• 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 31: Conformance To Ec Directives
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.

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.

CPU Unit Operation 2-4-1 General Flow The following flowchart shows the overall operation of the CPU Unit. First the user program is executed and then I/O is refreshed and peripheral servicing is performed. These processes are then repeated in cyclic fashion.
Page 117: I/O Refreshing And Peripheral Servicing
CP-series Expansion I/O Units and I/O words in the CIO Area • Refreshing between CJ-series Special I/O Units and CJ-series CPU Bus Units and the words allocated to these in the CIO Area (and for CPU Bus Units, words allocated in the DM Area) All I/O refreshing is performed in the same cycle (i.e., time slicing is not used).
Page 118: I/O Refresh Methods
CJ-series Special I/O Unit, CJ-series CPU Bus Unit, USB port, serial port, and communications port servicing is allocated 4% of the previous cycle time by default (the default can be changed) for each service. If servicing is sepa- rated over many cycles, delaying completion of the servicing, set the same allocated time (same time for all services) rather than a percentage under execute time settings in the PLC Setup.
Page 119 Note IORF(097) has a relatively long execution time which increases with the num- ber of words being refreshed. Be sure to consider the affect of this time on the overall cycle time. Refer to the CP Series CP1H Programmable Controllers...

Page 132: 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.
Page 133: Interrupt Response Times
20 ms Minimum I/O response time = 1 ms + 20 ms + 0.1 ms = 21.1 ms Maximum I/O response time = 1 ms + (20 ms × 2) + 0.1 ms = 41.1 ms Input Response Input response times can be set in the PLC Setup. Increasing the response Times time reduces the effects of chattering and noise.
Page 134 The length of the interrupt response time for scheduled interrupt tasks is 1 ms max. There is also an error of 80 µs in the time to the first scheduled interrupt (0.5 ms min.). Note...

Page 207: Using Index Registers
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 209: 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 220 Section 5-1 Interrupt Functions If you click the X Button in the upper-right corner of the window, you can cre- ate the program that will be executed as interrupt task 140. The programs allocated to each task are independent and an END(001) instruction must be input at the end of each program.
Page 221 The interrupt occurs during processing of the +B instruction and the result is saved temporarily without being written to the destination word (D0). The interrupt task transfers the value of #0010 to D0, but the saved result of the +B instruction (1235) is written to D0 when processing returns to the cyclic task.

Page 227: Input Interrupts (Counter Mode)
Refer to 5-1-2 Input Interrupts (Direct Mode) for details. • The counter input mode can be set to up or down (incrementing or decre- menting) with MSKS(690). • The counter-mode input interrupts start the same interrupt tasks (140 to 147) as the direct-mode input interrupts.
Page 228 Note The input interrupt (counter mode) function is one of the input interrupt func- tions and executes an interrupt based on the pulse count. If the input pulse frequency is too high, interrupts will occur too frequently and prevent normal cyclic task processing.

Page 230: 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 231 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.
