Omron · NJ/NX-series Machine Automation Controller
The NX Unit detected that the I/O power supply was turned ON. This is an informational event confirming the successful detection of the I/O power supply status by the NX Unit.
Click steps to track your progress.
Measure the input voltage to the I/O power supply unit to ensure stability and conformity with specified tolerances.
Measure the output voltage from the I/O power supply unit at the connection points to the NX I/O modules, confirming stable and correct voltage levels.
Inspect all power and communication cabling between the I/O power supply and the NX I/O modules for secure connections, signs of damage, or potential intermittent contact.
Review the Omron NJ/NX controller's event log for the frequency and sequence of the 'I/O Power Supply ON Detected' event (84850000 hex) to identify any patterns of instability or unexpected power cycling.
