    !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 32 !Caution Confirm safety before transferring data files stored in the file memory (Mem- ory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a peripheral tool. Otherwise, the devices connected to the output unit may mal- function regardless of the operation mode of the CPU Unit.

    PLC to which is mounted a non-insulated Unit (CS1W-CLK12/52(-V1) or CS1W-ETN01) connected to an external power supply. A short-circuit will be created if the 24 V side of the external power supply is grounded and the 0 V side of the peripheral device is grounded. When connecting a peripheral device to this type of PLC, either ground the 0 V side of the external power supply or do not ground the external power supply at all.

    1-1-1 Program Capacity The program capacity tells the size of the user program area in the CPU Unit and is expressed as the number of program steps. The number of steps required in the user program area for each of the CS/CJ-series instructions varies from 1 to 7 steps, depending upon the instruction and the operands used with it.

  • Page 42: Differentiated Instructions

    PLC is converted for a CS/CJ- series PLC based on the assumption that 1 word is 1 step. Refer to the infor- mation at the end of SECTION 4 Instruction Execution Times and Number of Steps for guidelines on converting program capacities from previous OMRON PLCs.

The input condition is OFF (P_Off is the Always OFF Flag), so the OUT instruction sets 000013, which is indirectly addressed by IR0, to OFF. The OUT instruction is executed, so IR0 is incremented. As a result, the PLC memory address 000014, which was incremented by +1 in the IR0, is stored.

  • Page 946: Pulse With Variable Duty Factor: Pwm(891) (Cj1M-Cpu21/22/23 Only)

    ORG(889) starts an origin return operation for pulse output 0 by outputting pulses using the CW/CCW method. According to the PLC Setup, the initial speed is 100 pps, the target speed is 200 pps, and the acceleration and deceleration rates are 50 Hz/4 ms.
  • Page 947 F specifies the frequency of the pulse output between 0.1 and 6,553.5 Hz (0.1 Hz units, 0001 to FFFF hex). The accuracy of the PMW(891) waveform that is actually output (ON duty +5%/ 0%) applies only to 0.1 to 1,000.0 Hz due to limitations in the output circuits.

  • Page 948: Step Instructions

    Example When CIO 000000 turns ON in the following programming example, PWM(891) starts pulse output from pulse output 0 at 200 Hz with a duty factor of 50%. When CIO 000001 turns ON, the duty factor is changed to 25%.
