The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
  • Page 22 Safety Precautions Symbols The circle and slash symbol indicates operations that you must not do. The specific operation is shown in the circle and explained in text. This example indicates prohibiting disassembly. The triangle symbol indicates precautions (including warnings). The specific operation is shown in the triangle and explained in text. This example indicates a precaution for electric shock.
  • Page 23 Safety Precautions Warnings WARNING During Power Supply Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. Do not attempt to take any Unit apart. In particular, high-voltage parts are present in the Power Supply Unit while power is supplied or immediately after power is turned OFF.
  • Page 24 Safety Precautions Unintended outputs may occur when an error occurs in variable memory or in memory used for CJ-series Units. As a countermeasure for such prob- lems, external safety measures must be provided to ensure safe operation of the system. Provide measures in the communications system and user program to ensure safety in the overall system even if errors or malfunctions occur in data link communications or remote I/O communications.
  • Page 25 Safety Precautions Cautions Caution Application Do not touch any Unit when power is being supplied or immediately after the power supply is turned OFF. Doing so may result in burn injury. Wiring Be sure that all terminal screws and cable connector screws are tightened to the torque specified in the relevant manuals.

  • Page 26: Precautions For Safe Use

    Precautions for Safe Use Precautions for Safe Use Disassembly and Dropping • Do not attempt to disassemble, repair, or modify any Units. Doing so may result in malfunction or fire. • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit malfunc- tion or burning.
  • Page 27 Precautions for Safe Use • Do not apply voltages or connect loads to the Output Units or slaves in excess of the maximum rat- ings. • Surge current occurs when the power supply is turned ON. When selecting fuses or breakers for external circuits, consider the above precaution and allow sufficient margin in shut-off performance.
  • Page 28 Precautions for Safe Use • Connecting cables or wiring the system • Connecting or disconnecting the connectors The Power Supply Unit may continue to supply power to the rest of the Controller for a few seconds after the power supply turns OFF. The PWR indicator is lit during this time. Confirm that the PWR indicator is not lit before you perform any of the above.
  • Page 29 EtherNet/IP Communications • All related EtherNet/IP nodes are reset when you transfer the settings for the CJ1W-EIP21 Ether- Net/IP Unit (including IP addresses and tag data links settings) from the Support Software. Confirm that the system will not be adversely affected by resetting nodes before you transfer the settings.
  • Page 30 Precautions for Safe Use • After you transfer the user program, the CPU Unit is restarted and communications with the Ether- CAT slaves are cut off. During that period, the slave outputs behave according to the slave settings. The time that communications are cut off depends on the EtherCAT network configuration. Before you transfer the user program, confirm that the system will not be adversely affected.

Operation may stop or malfunctions may occur. • Locations subject to direct sunlight • Locations subject to temperatures or humidity outside the range specified in the specifications •...
  • Page 33 Precautions for Correct Use Error Processing • In applications that use the results of instructions that read the error status, consider the affect on the system when errors are detected and program error processing accordingly. For example, even the detection of a minor error, such as Battery replacement during operation, can affect the system depending on how the user program is written.
  • Page 34 Precautions for Correct Use Battery Replacement • Be sure to install a replacement Battery within two years of the production date shown on the Battery label. • Turn ON the power after replacing the Battery for a CPU Unit that has been unused for a long time. Leaving the CPU Unit unused again without turning ON the power even once after the Battery is replaced may result in a shorter Battery life.

  • Page 384: Variable Memory Allocation Methods

    Appendices Variable Memory Allocation Methods You must be aware of the way in which memory is allocated to variables to align the memory locations of the members of structure or union variables with variables in other devices. Adjustments are neces- sary mainly when structure variables are used in the following type of communications with other devices.
  • Page 385 Appendices The alignments and the amounts of memory that are allocated for the basic data types and enumera- tions are given below. Amount of memory that Data type Alignment [bytes] is allocated [bytes] BOOL BYTE, USINT, or SINT WORD, UINT, or INT DWORD, UDINT, or DINT LWORD, ULINT, or LINT REAL...
  • Page 386 Appendices Precautions for Correct Use Precautions for Correct Use Amount of Memory That Is Allocated for BOOL Arrays Two bytes are allocated in memory for individual BOOL variables, BOOL structure members, and BOOL union variables. However, for a BOOL array, two bytes of memory are not allocated for each element.
  • Page 387 Appendices  Variables with Four-byte Alignments (e.g., DWORD) Four bytes of memory are allocated for the four-byte alignment. The location of the first byte of data in memory is an integer multiple of four bytes. Therefore, if a variable with a two-byte alignment, such as WORD data, is inserted, two bytes of unused memory will remain.
  • Page 388 Appendices  Variables with Eight-byte Alignments (e.g., LWORD) Eight bytes of memory are allocated for the eight-byte alignment. The location of the first byte of data in memory is an integer multiple of eight bytes. Therefore, if a variable with a two-byte alignment, such as WORD data, is inserted, six bytes of unused memory will remain.
  • Page 389 Appendices Arrays A continuous section of memory is allocated for the elements of the array based on the data size of the data type of the array variable. The alignment of an array is the same as alignment of the data type of the elements.

Variable Alignment [bytes] Amount of memory that is allocated [bytes] Data Type Definitions Memory First byte + Name...
  • Page 392 Appendices Unions For a union variable, the members overlap in the same memory locations. The alignment of a union is largest alignment of all of the members. The amount of memory that is allocated is the largest amount of memory that is allocated for any of the members. Example: The alignments and the amounts of memory that are allocated for the four variable declara- tions given in the following figure are given in the following table.

  • Page 393: A-4-2 Important Case Examples

    Appendices A-4-2 Important Case Examples When you exchange structure variable data between an NJ-series CPU Unit and a remote device, you must align the memory configuration of the structure variable members with those of the remote device. This section describes what to do in either the NJ-series CPU Unit or in the remote device. Additional Information This is not necessary when you exchange data between NJ-series CPU Units.
