If products are used in a different way from that specified by manufacturers, the protection function of the products may not work properly. The precautions given in this manual are concerned with this product. For the safety precautions of the programmable controller system, refer to the User’s Manual for the CPU module.  \nIn this manual, the safety precautions are ranked as \" WARNING\" and \" CAUTION\" .  \n\n| | Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.\u003Cbr>Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage. |\n| --- | --- |\n\nNote that the  CAUTION level may lead to serious consequences according to the circumstances. Always follow the precautions of both levels because they are important for personal safety.  \nPlease save this manual to make it accessible when required and always forward it to the end user.  \n[Design Instructions]  \n\n|  WARNING |\n| --- |\n| 􀃜 When data change, program change, or status control is performed from a personal computer to a running\u003Cbr>programmable controller, create an interlock circuit outside the programmable controller to ensure that the whole system always operates safely.\u003Cbr>Furthermore, for the online operations performed from a personal computer to a programmable controller CPU, the corrective actions against a communication error due to such as a cable connection fault should be predetermined as\u003Cbr>a system. |\n\n[Security Precautions]  \n\n|  WARNING |\n| --- |\n| 􀃜 To maintain the security (confidentiality, integrity, and availability) of the programmable controller and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other cyberattacks from external devices via the network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions. |\n\n[Startup and Maintenance Instructions]  \n\n|  CAUTION |\n| --- |\n| 􀃜 The online operations performed from a personal computer to a running programmable controller CPU (Program change when a programmable controller CPU is RUN, operating status changes such as forced input/output operation and RUN-STOP switching, and remote control operation) must be executed after the manual has been carefully read and the safety has been ensured.\u003Cbr>When changing a program while a programmable controller CPU is RUN, it may cause a program corruption in some operating conditions. Fully understand the precautions described in GX Works2 Version 1 Operating Manual (Common) before use.\u003Cbr>􀃜 The positioning test functions of OPR, JOG, inching or positioning data for QD75/LD75 positioning module must be executed with the programmable controller set to STOP after the manual has been carefully read and the safety has been ensured. Specially when executing the function on the network system, ensure the safety thoroughly since the machinery whose operation cannot be checked by an operator may be activated. The operation failure may cause the injury or machine damage. |\n\n CONDITIONS OF USE FOR THE PRODUCT   \n(1) MELSEC programmable controller (\"the PRODUCT\") shall be used in conditions;  \ni) where any problem, fault or failure occurring in the PRODUCT, if any, shall not lead to any major or serious accident; and  \nii) where the backup and fail-safe function are systematically or automatically provided outside of the PRODUCT for the case of any problem, fault or failure occurring in the PRODUCT.  \n(2) The PRODUCT has been designed and manufactured for the purpose of being used in general industries.  \nMITSUBISHI ELECTRIC SHALL HAVE NO RESPONSIB","cbCaipsEbENlsCVZ","https://ap.wps.com/l/cbCaipsEbENlsCVZ","pdf",3791516,108,"English","# SAFETY PRECAUTIONS\n## WARNING and CAUTION ranking\n## Design Instructions\n## Security Precautions\n## Startup and Maintenance Instructions\n## CONDITIONS OF USE FOR THE PRODUCT","[{\"question\":\"What are the WARNING and CAUTION levels used for in this manual?\",\"answer\":\"The manual ranks safety precautions into WARNING and CAUTION.
