The following sequence describes the steps necessary to perform one of the reset operations.
This combination of DIP switch settings and mode switch manipulation is purposely
complex to prevent these reset operations from being accidentally executed.
Clear only the Network Settings
This reset function will clear ONLY the Network settings, which consists of the Module ID,
Module Name, Module Description, IP Address, Subnet Mask and Gateway Address.
•
Begin by powering down the controller.
• Remove the controller from the base and record the location of the DIP switches (so they can be set back
to their original position after the manual reset is finished).
• Next set ONLY DIP #1 and #7 ON to perform the Clear Only the Network Settings operation, make
sure all other DIP switches are OFF.
• Reinstall the controller in the base.
• Set the controller mode switch to TERM (the center location) and power up the controller.
• At this point the LEFT bank of 4 LEDs should be blinking the ‘stay in the boot loader sequence’, that
is, they should be blinking in sequence, from top to bottom then back to the top, alternating between
red and green.
• Move the controller mode switch to RUN (to the left).
• Move the controller mode switch to TERM (to the center).
• Move the controller mode switch to RUN (to the left).
• Move the controller mode switch to TERM (to the center).
• Move the controller mode switch to STOP (to the right).
• Move the controller mode switch to TERM (to the center) - the LEFT bank of 4 LEDs should now
be ON.
NOTE:
If you want to terminate the reset at this point you can do so by moving switch to RUN instead of
STOP or powering down the controller.
• Move the controller mode switch to STOP (to the right) - the RIGHT bank of 4 LEDs should now
be ON.
NOTE:
If you want to terminate the manual reset at this point you can only do so by powering down the
controller.
• Move the controller mode switch to TERM (to the center) - the LEFT bank LEDs begin flashing the
power up sequence, and the ROM led should briefly be ON indicating that the data in the ROM is
being rewritten. The LEDs will then begin flashing the ‘staying in boot loader’ sequence indicating
the reset is complete.
• Power down the controller.
• Remove the controller from the base and return the DIP switches to their original positions.
• Set the controller mode switch to TERM (in the center location).
