Reset Modes: a Brief Summary
The MLC Plus 84 Series controllers offer the following reset modes:
•
Use Factory Firmware
:
Press and hold the rear panel
Reset
button while applying power to the unit. Keep holding
the button down until the Reset LED blinks twice, or for 6 seconds, then release the button.
The control processor enters factory firmware mode. For units with firmware prior to version
2.00.0001, the LED blinks quickly. Use this mode to revert to factory firmware in the event of a
firmware failure.
Do not continue to operate the controller using the factory firmware version. If you want to use
the factory default firmware version, you must upload that version again.
•
Project Recovery
:
See the
MLC Plus 84 Series User Guide
for instructions. Use this mode to recover the project in
the event of a lost user name and password.
•
Run/Stop Program
:
Hold down the
Reset
button for about 3 seconds, until the Reset LED blinks once. Release
and press the
Reset
button momentarily (for <1 second) within 1 second. (Nothing happens if
the momentary press does not occur within 1 second.) The LED blinks 2 times if the program is
starting. The LED blinks 3 times if the program is stopping. This mode allows you to restart any
scripts or events stopped by an IP settings reset.
•
Toggle DHCP Client
:
Press the
Reset
button five times (consecutively). Release the button. Do not press the button
within 3 seconds following the fifth press. Use this mode to enable or disable the DHCP client
for the LAN port.
•
The
Reset
LED blinks 6 times if the DHCP client is enabled.
•
The
Reset
LED blinks 3 times if the DHCP client is disabled.
NOTES:
•
DHCP toggle mode is supported on firmware version
3.00.0000
or higher.
•
By default DHCP is off and the unit uses a static IP address.
•
When you disable DHCP, the unit uses the factory default IP address
(192.168.254.250).
•
Reset All IP Settings
:
Press and hold the rear panel
Reset
button for 6 seconds. After the Reset LED blinks twice,
release and momentarily press the
Reset
button. Use this mode to reset all network settings
to factory default values without affecting user-loaded files. This reset mode also stops any
running scripts and events.
•
Reset to Factory Defaults
: Press and hold the rear panel
Reset
button for 9 seconds. After the Reset LED blinks three
times, release and momentarily press the
Reset
button within 1 second. Use this mode to
return the controller to factory default settings. This mode also deletes all user-loaded files and
configurations.
For detailed information on each mode and its use, see the

Rev. C, 08/2018: Changed wording of various items in the
reset modes summary:
For the Use Factory Firmware mode, added more text to
clarify how long to hold the button, and on LED behavior
for units with versions prior to 2.x.
Per peer reviewer (Sean), added (for IPCP guides) “
Do
not continue to operate the control processor using
the factory firmware version. If you want to use the
factory default firmware version, you must upload
that version again.
“
Added Run/Stop Program mode and DHCP toggle mode.
For the Reset All IP Settings mode, noted that the mode
stops running scripts/events.
For the Reset to Factory Defaults mode, noted that the
reset deletes user-loaded files and configs.
Rev. C, 09/2018: Removed the
“About Global Configurator (with
GC Professional and GC Plus
Modes)” section (as has been done
in the IPL Pro and IPCP Pro setup
guides), which isn’t needed here
and is partially redundant with text
earlier in this guide.
