Installation Chapter 2
Reset Pushbutton GuardPLC 1600 and 1800 controllers and distributed I/O are equipped
with a reset pushbutton. Reset via the pushbutton is necessary if you:
•
forget the password to go online via the programming software.
•
are unable to determine the IP address and SRS of the controller.
The pushbutton is accessible through a small round hole at the top of
the housing, approximately 4…5 cm (1.6…2.0 in.) from the left rim
and recessed approximately 9.5 mm (0.375 in.).
To reset, press and hold the pushbutton while restarting the controller
by cycling power. Hold the reset pushbutton until the PROG status
indicator stops flashing. Pressing the Reset pushbutton during
operation has no affect.
After a reset, the IP address, SRS, and login accounts are temporarily
reset to their default settings.
•
IP = 192.168.0.99
•
SRS = 60000.1
•
Login Username = Administrator
•
Login Password = [none]
At the next power cycle, these settings will be reset to the last values
stored into Flash. This means that either:
•
the settings prior to the reset will be restored.
•
if any settings were changed after the reset, these new settings
will still be in effect.
IMPORTANT
Activate the reset pushbutton by using an insulated pin to
prevent short-circuits.
