When the application is stopped, all PLC configuration settings (as reported on the PLC Configuration web
pages) are restored to default values.
The controller is then reset, and the controller remains stopped on the subsequent startup.

EFAULTS
Pressing and holding the recessed pushbutton for greater than 15 seconds causes the controller to return
to as-shipped factory defaults by pressing the button for greater than 15 seconds. This action will reset all
PLC configuration settings to default (see list in
R
ESET
C
ONFIGURATION
S
ETTINGS
section above) and delete all
user files including application programs and source files from the internal SD card.
After the button is pressed and held for 10 seconds, the display shows
Cr
(see
R
ESET
C
ONFIGURATION
S
ETTINGS
description above). If the button press is maintained for another second, the front panel display
shows countdown for ‘seconds to Factory Reset’ (4
-1). If the pushbutton is released any time during this
period until countdown reaches zero, the button press is treated as a
R
ESET
C
ONFIGURATION
event as
described above.
If the button press is held until the
F
ACTORY
R
ESET
countdown completes, the display changes to
Fr
(indicating pending
F
ACTORY
R
ESET
) and displays this value until the button is released or power is
removed. Releasing the button when
Fr
is displayed initiates a
F
ACTORY
R
ESET
event.
If the controller is in
RUN
or
LOGIC STOP
state when the
F
ACTORY
R
ESET
event is detected, the application
will be halted and operational data stored (equivalent to stopping the application from Workbench)
before the reset is triggered.

HTTP Data Server
The Janus controller includes an HTML Data Server that provides an embedded HMI function. Using the Data
Server, you can access
“live”
controller variable data using any recent version of a standard web browser
(Microsoft Edge, Internet Explorer 11, Mozilla Firefox, or Google Chrome) on any PC or internet-capable smart
device. Variable data is constantly updated from the controller database. Read/write services allow you to modify
variables values from the web page based on a user-designed graphics page configuration. You have complete
control over which PLC control variables are accessible via the web browser. See the
Janus Workbench
help
system for information regarding configuration and use of the Data Server.
Access to the Data Server can be controlled via Username/Password set in the controller web server
