Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of an NJ-series Controller. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions. The following notation is used.
Page 22 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 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 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 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 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 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 • 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. Refer to the relevant manuals for surge current specifications.

Page 29 • You cannot upload or download information for forced refreshing with the Sysmac Studio. After downloading data that contains forced refreshing, change to RUN mode and then use the Sys- mac Studio to perform the operation for forced refreshing. Depending on the difference in the forced status, the control system may operate unexpectedly. •...
Page 30 • EtherCAT communications are not always established immediately after the power supply is turned ON. Use the system-defined variables in the user program to confirm that communications are estab- lished before attempting control operations. • 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.
Page 31 Unit Replacement • We recommend replacing the Battery with the power turned OFF to prevent the CPU Unit’s sensitive internal components from being damaged by static electricity and to prevent malfunctions. The Bat- tery can be replaced without turning OFF the power supply. To do so, always touch a grounded piece of metal to discharge static electricity from your body before you start the procedure.
Page 32: 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 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 SD Memory Cards • Insert the SD Memory Card all the way. • Do not turn OFF the power supply to the Controller during SD Memory Card access. The files may be corrupted. If there is a corrupted file in the SD Memory Card, the file is automatically deleted by the restoration function when the power supply is turned ON.

Page 177: I/O Communication Characteristics
5 Operation I/O Communication Characteristics 5-5-1 I/O Data Configuration  I/O Data Configuration Each slave device defines its I/O data size, sequence and format by means of I/O modules, each of which consists of one or more bytes, containing a PROFIBUS defined coding scheme. The I/O mod- ules can define input data, or output data or both input and output data.
Page 178 5 Operation • I/O modules per slave device, are mapped in the order in which they were selected, when set- ting up the slave device. Furthermore, Input area 1 is by default mapped to CIO 3300, whereas Output area 1 is by default mapped to CIO 3200.
Page 179 The figure below shows an example of the effects of Auto Addressing on (re)allocation of I/O mod- ules. In the original I/O configuration on the left, the first slave - an OMRON CJ1W-PRT21 - con- sisted of two I/O modules. In new configuration one I/O module was inserted, and subsequent modules were re-allocated in the process.
Page 180 5 Operation One I/O module of two output Initial I/O Configuration words was inserted, and re-allocated subsequent I/O modules. Note The start address of Output area 1 in the example remains the same after adding an I/O module.  Re-allocating I/O Modules After setting up the initial I/O configuration the I/O modules can be re-mapped to the second Input/Output area.
Page 181 5 Operation Hold the left mouse button and drag the I/O module to the Input/Output area of choice. Release the left mouse button to drop the module in place. Note The area to place the module in must be empty. The area to put the modules in does not need to be selected first.
Page 182 5 Operation Initial I/O configuration The first Output modules of slave device #2 and #3 were moved to Output area 2. The example shows that the sequence of slave addresses is maintained, the sequence of I/O mod- ules selected is maintained and the I/O modules are allocated to the lowest address of the area. 5-30 CJ-series PROFIBUS Master Unit Operation Manual for NJ-series CPU Unit (W509)
Page 183 5 Operation  Enable/Disable Auto Addressing The Auto Addressing feature can be disabled in the CJ1W-PRM21 Master DTM. Perform the follow- ing sequence to control Auto Addressing. Open the CJ1W-PRM21 Master DTM - Configuration User Interface. Select the Master Setup tab. Enable/Disable Auto Addressing by selecting/deselecting the Auto Addressing checkbox in the Support box.
Page 184 5 Operation Initial I/O Configuration Note: Auto-addressing is disabled Output module 2 of slave device #2 was moved to Output area 2, location CIO 3401, leaving behind a gap in Output area 1.  Removing Gaps from the I/O Mapping Since gaps in the I/O mapping are generally undesirable, the CJ1W-PRM21 Master DTM provides a means to remove all gaps, after finalizing the I/O mapping procedure.
Page 185 5 Operation  Compressing the I/O Mapping Compressing re-allocates all I/O modules in an area as close to the start of the area as possible. Compressing an area does not change the sequence of the slave devices and/or the I/O modules. It only removes the unused memory gaps.
Page 186: Supported Data Types
5 Operation The total size per Input/Output area can be found for each area, next to the CPU memory area selection box (for example, the figure above; Output area 1 occupies 7 words).
