Working Principle
The S2PU72A continuously scans the user program stored in memory and processes input signals from connected I/O modules. Based on the program logic, it calculates output states and updates digital or analog outputs. The module supports multitask execution, allowing different control tasks to run at suitable cycles. Communication ports enable programming, monitoring, data collection and connection to touch panels or host computers. The built-in Flash ROM helps retain programs and parameters, while the backup battery maintains memory data during power-off conditions.

Installation Requirements

  • Install in a Toshiba V series model 2000 controller rack.
  • Ensure the rack power supply matches the module requirement.
  • Insert the module firmly into the correct slot.
  • Connect the TOOL port and LINK port only when the system is properly configured.
  • Verify that the operation mode switch is set correctly before startup.
  • Install the backup battery correctly if replacement is required.
  • Keep ventilation spaces around the controller rack.
  • Avoid installation in locations with excessive dust, moisture or vibration.

Precautions for Use

  • Do not change the HALT/RUN switch during unsafe operating conditions.
  • Back up programs and parameters before maintenance.
  • Replace the backup battery only according to Toshiba instructions.
  • Avoid hot insertion or removal unless permitted by the system manual.
  • Check FAULT and BAT LEDs regularly.
  • Use the real-time trace function for diagnostics rather than frequent program changes during operation.
  • Confirm I/O module compatibility before system expansion.
  • Refer to the Toshiba V series S2 CPU module user manual for wiring, programming, troubleshooting and maintenance details.
