Page 21: Safety Precautions
Safety Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of a CJ-series CompoNet Master Unit. The safety precautions that are provided are extremely important to safety.
Page 22: Symbols
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 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 WARNING Fail-safe Measures Unintended outputs may occur when an error occurs in variable memory or in memory used for CJ-series Units. As a countermeasure for such problems, 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 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 • 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. Refer to the relevant manuals for surge current specifications. Refer to the NJ-series CPU Unit Hard- ware User’s Manual (Cat.
Page 28 Precautions for Safe Use 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 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. If the EtherCAT network configuration contains only OMRON EtherCAT slaves, communications are cut off for a maximum of 45 seconds.
Page 30 Precautions for Safe Use • If frames sent to EtherCAT slaves are lost due to noise or other causes, slave I/O data is not commu- nicated, and the intended operation is sometimes not achieved. If noise countermeasures are required, use the _EC_InDataInvalid (Input Data Disable) system-defined variable as an interlock condition in the user program.
Page 31 Precautions for Safe Use • Make sure that the required data, including the user program, configurations, settings, variables, and memory used for CJ-series Units, is transferred to a CPU Unit that was replaced and to externally connected devices before restarting operation. Be sure to include the routing tables, network parameters, and other CPU Bus Unit data, which are stored in the CPU Unit.
Page 32: Precautions For Correct Use
Precautions for Correct Use Precautions for Correct Use Storage, Mounting, and Wiring • Do not operate or store the Controller in the following locations. 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 35: Regulations And Standards
Concepts • EMC Directive 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.* Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.

Page 42: Componet Networks
1 Introduction CompoNet Networks 1-1-1 Features CompoNet Networks feature easy operation and installation in a component-level network that con- nects Controllers and onsite I/O. The CPU Unit and CompoNet Slave Units cyclically exchange I/O information through the CompoNet Master Unit, refreshing I/O in sync with the task periods of the CPU Unit.
Page 43 1 Introduction Communications Cables CompoNet Networks use Round Cable I, Round Cable II, Flat Cable I (DCA4-4F10 Standard Flat Cable), and Flat Cable II (DCA5-4F10 Sheathed Flat Cable) for Communications Cables. Master Unit The Master Unit manages the CompoNet Network and transfers I/O data between the CPU Unit and the Slave Units.
Page 44 1 Introduction • Sub-branch line: The transmission path created using a T-branch from a branch line. (T-branching is not possible from sub-branch lines.) Note Due to differences in functionality, the same type of cable must be used between the trunk line and a branch line, a sub-trunk line and a branch line, and a branch line and a sub-branch line.
Page 45: Segments
1 Introduction 1-1-3 Segments Segment Layers When Repeater Units are used, the CompoNet Network is divided into segments by the Repeater Units. Each segment is connected to the same network, but is isolated electrically.

4 Installation and Wiring 4-4-5 Precaution in Supplying Power to Slave Units When supplying communications power and I/O power, the allowable currents of cables and connec- tions, the voltage drop, and the capacity and location of power supplies must be considered. Allowable Current Restrictions Do not allow the total current consumption of all Slave Units to exceed the allowable current of the com- munications cables and connectors.
Page 150 4 Installation and Wiring Voltage Drop Cable Voltage Drop The voltage drop must be considered so that the power supply voltage at the Slave Unit that is the farthest from the power supply will still be within the allowable power supply range. The voltage drop is expressed by the following formula.
Page 151: Precautions On Locating The I/O Power Supply
4 Installation and Wiring 4-4-6 Precautions on Locating the I/O Power Supply When building a system, the supply methods for communications power and I/O power must be consid- ered. Not only hardware, such as selecting the power supplies and cables based on allowable currents and voltage drop, be considered, but also system operation for power supply errors, costs, and other software issues must be considered when studying power supply methods.
Page 152: Other Precautions
4 Installation and Wiring 4-4-7 Other Precautions Power Supply Errors The location of power supplies and the grouping of Slave Units should be considered based on whether the overall system is to be stopped when a power supply error occurs. If it is necessary to prevent the overall system from stopping to ensure system safety, consider placing power supplies in more than one location and consider the way Slave Units should be grouped when supplying power.
