Print LED
The Print LED lights when the OIT is printing and blinks when the printer cannot print
for any reason (such as being off line, out of paper, etc.). Once blinking, the Print LED
continues to blink until the OIT successfully sends a print command. For more
information on printing, refer to CHAPTER 9: Using a Serial Printer.
Status LEDs
The eight Status LEDs can be used to monitor eight consecutive PLC coils starting with the
PLC address specified in OITware-200. The OIT reads each PLC coil once per second. If the
coil is set, the corresponding Status LED is turned on. If the coil is clear, the corresponding
Status LED is turned off. If not required, the status LEDs can be disabled.
The OIT4450 and OIT5400 have a clear area where you can insert a custom legend to
label the Status LEDs. For more information on the slide-in legend, refer to APPENDIX
B: Slide-in Legend Templates.
To enable the Status LEDs:
1. From the Configuration menu, choose LED Control Editor. The LED Control Editor
dialog box appears.
2. In the OIT Status LEDs group box, select the Enable? check box.
3. In the OIT Status LEDs group box, in the Address scroll box, select the starting PLC
coil address.
4. Choose the Done button to return to the OITware-200 main screen.
