  • Page 2 SAFETY PRECAUTIONS (Always read these instructions before using this equipment.) Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The instructions given in this manual are concerned with this product. For the safety instructions of the programmable controller system, please read the CPU module user’s manual.
  • Page 3 [Design Precautions] DANGER When a communication error occurs on PROFIBUS-DP, the status of the faulty station is as shown below. Create an interlock circuit in the sequence program using the communication status information to ensure the system operates safely (Input X1, buffer memory 5A20 to 5B19 (23072 to 23321)).
  • Page 4 [Design Precautions] DANGER When the QJ71PB92V is mounted in a redundant system, set the watchdog timer for DP-Slaves so that the calculation formula shown in PROFIBUS-DP Master Module User's Manual. If the formula is not satisfied, a watchdog timer error occurs in DP-Slaves during system switching. CAUTION Do not bunch PROFIBUS cables with the main circuit or power wires, or install them close to each other.
  • Page 5 [Installation Precautions] CAUTION Do not directly touch the module's conductive parts or electronic components. Touching the conductive parts could cause an operation failure or give damage to the module. [Wiring Precautions] DANGER Be sure to shut off all phases of the external power supply used by the system before wiring PROFIBUS cables.
  • Page 6 [Startup and Maintenance Precautions] DANGER Before cleaning, be sure to shut off all phases of the external power supply used by the system. Failure to do so may cause electrical shocks. CAUTION Do not disassemble or modify the module. Doing so could cause trouble, erroneous operation, injury, or fire. Use any radio communication device such as a cellular phone or a PHS phone more than 25cm (9.85 inch) away in all directions of the programmable controller.
