    PRECAUTIONS This section provides general precautions for using the CS/CJ-series Programmable Controllers (PLCs) and related devices. The information contained in this section is important for the safe and reliable application of Programmable Controllers. You must read this section and understand the information contained before attempting to set up or operate a PLC system.

  • Page 28

    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 29

    Safety Precautions !WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. !WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.

  • Page 30

    Operating Environment Precautions !Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burning or malfunction. !Caution Do not touch the Power Supply Unit when power is being supplied or immedi- ately after the power supply is turned OFF.

  • Page 31

    Application Precautions A Programming Console can, however, be used to edit multitask pro- grams originally created with the CX-Programmer. !WARNING Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury. • Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground of 100 Ω...

  • Page 32

    Application Precautions • Always turn ON power to the PLC before turning ON power to the control system. If the PLC power supply is turned ON after the control power sup- ply, temporary errors may result in control system signals because the output terminals on DC Output Units and other Units will momentarily turn ON when power is turned ON to the PLC.

  • Page 33

    Application Precautions • Separate the line ground terminal (LG) from the functional ground termi- nal (GR) on the Power Supply Unit before performing withstand voltage tests or insulation resistance tests. Not doing so may result in burning. • Install the Units properly as specified in the operation manuals. Improper installation of the Units may result in malfunction.

    Operating Modes Section 1-4 Programming Device operations like monitoring the status of program execu- tion (monitoring programs and monitoring I/O memory) are enabled. Use this mode for normal system operation. Task execution is the same as in MONITOR mode. See 10-2 CPU Unit Operating Modes in the Operation Manual for more details on operations that are available in each operating mode.

  • Page 47

    Section 1-4 Operating Modes 1-4-3 Startup Mode Refer to the Operation Manual for details on the Startup Mode setting for the CPU Unit. Note With CJ1, CS1-H, CJ1-H, CJ1M, or CS1D CPU Units, the CPU Unit will start in RUN Mode if a Programming Console is not connected. This differs from the default operation for a CS1 CPU Unit, which will start in PROGRAM Mode by default if a Programming Console is not connected.

  • Page 48: Programs And Tasks

    A. When execution of program B is completed, the rest of program A would be executed from the place where execution was interrupted. With earlier OMRON PLCs, one continuous program is formed from several continuous parts. The programs allocated to each task are single programs that terminate with an END instruction, just like the single program in earlier PLCs.

  • Page 49

    Programs and Tasks Section 1-5 One feature of the cyclic tasks is that they can be enabled (executable status) and disabled (standby status) by the task control instructions. This means that several program components can be assembled as a task, and that only spe- cific programs (tasks) can then be executed as needed for the current product model or process being performed (program step switching).

    Description of Tasks Section 1-6 Task Execution Time While a task is on standby, instructions in that task are not executed, so their OFF instruction execution time will not be added to the cycle time. Note From this standpoint, instructions in a task that is on standby are just like instructions in a jumped program section (JMP-JME).

    Basic Concepts Section 2-1 General Structure of the A ladder diagram consists of left and right bus bars, connecting lines, input Ladder Diagram bits, output bits, and special instructions. A program consists of one or more program runs. A program rung is a unit that can be partitioned when the bus is split horizontally.

  • Page 80

    Section 2-1 Basic Concepts Basic Ladder Program Concepts 1,2,3... 1. When ladder diagrams are executed by PLCs, the signal flow (power flow) is always from left to right. Programming that requires power flow from right to left cannot be used. Thus, flow is different from when circuits are made up of hard-wired control relays.

  • Page 81

    Basic Concepts Section 2-1 5. Output bits can also be used as input bits. 0002 0002 Restrictions 1,2,3... 1. A ladder program must be closed so that signals (power flow) will flow from the left bus bar to the right bus bar. A rung error will occur if the program is not closed (but the program can be executed).

    Basic Concepts Section 2-1 Mnemonic Execution Order PLCs execute ladder programs in the order the mnemonics are entered so instructions may not operate as expected, depending on the way rungs are written. Always consider mnemonic execution order when writing ladder dia- grams.

  • Page 91: Precautions

    Precautions Section 2-2 Precautions 2-2-1 Condition Flags Using Condition Flags Conditions flags are shared by all instructions, and will change during a cycle depending on results of executing individual instructions. Therefore, be sure to use Condition Flags on a branched output with the same execution condi- tion immediately after an instruction to reflect the results of instruction execu- tion.

    Precautions Section 2-2 Using Execution Results in N.C. and N.C. Inputs The Condition Flags will pick up instruction B execution results as shown in the example below even though the N.C. and N.O. input bits are executed from the same output branch. Instruction A Incorrect Reflects instruction A execution...

  • Page 93

    Precautions Section 2-2 Example: The following example will move #0200 to D00200 if D00100 con- tains #0010 and move #0300 to D00300 if D00100 does not contain #0010. Incorrect Reflects CMP execution results. Reflects MOV execution results. The Equals Flag will turn ON if D00100 in the rung above contains #0010. #0200 will be moved to D00200 for instruction (1), but then the Equals Flag will be turned OFF because the #0200 source data is not 0000 Hex.

  • Page 94

    Precautions Section 2-2 Using Execution Results from Differentiated Instructions With differentiated instructions, execution results for instructions are reflected in Condition Flags only when execution condition is met, and results for a pre- vious rung (rather than execution results for the differentiated instruction) will be reflected in Condition Flags in the next cycle.

  • Page 95

    Precautions Section 2-2 When the ER Flag is ON, the status of other Condition Flags, such as the <, >, OF, and UF Flags, will not change and status of the = and N Flags will vary from instruction to instruction. Refer to the descriptions of individual instructions in the CS/CJ-series Pro- grammable Controllers Instructions Reference Manual (W340) for the condi- tions that will cause the ER Flag to turn ON.

  • Page 96

    Precautions Section 2-2 As an example, consider the results of executing a block transfer with XFER(070) if 20 words are specified for transfer beginning with W500. Here, the Work Area, which ends at W511, will be exceeded, but the instruction will be executed without turning ON the Error Flag.

  • Page 97

    Precautions Section 2-2 Note Instructions that specify program areas cannot be used for programs in other tasks. Refer to 4-2-2 Task Instruction Limitations for details. Subroutines Place all the subroutines together just before the END(001) instruction in all programs but after programming other than subroutines. (Therefore, a subrou- tine cannot be placed in a step ladder, block program, FOR - NEXT, or JMP0 - JME0 section.) If a program other than a subroutine program is placed after a subroutine program (SBN to RET), that program will not be executed.
