The WCC III - MCD
The WCC III – MCD
Overview
The WCC III – MCD was converted from the Windows XP
operating system over to the Ubuntu version of Linux using the
command line interface only and was then released by WattMaster
Controls in October of 2009. The main function of the WCC
III – MCD is to provide a hardware and software platform for a
program that WattMaster Controls has developed that is called
“BACKTASK.exe”. The BACKTASK.exe program is a multiple
BACKground TASKing application program.
BACKTASK.EXE (SS5009)
The BACKTASK.exe program performs many functions such
as:
• USB communications to the internal MCOMM board
• Time clock functions
• Analog/binary global processing
• Overrides of control points
• Holiday scheduling
• Optimal starts
• PID programs
• Shed /Restore programs
• Duty cycle programs
• Proportional Programs
• Tenant Overrides
• Emailing of alarms
The BACKTASK.exe program also provides for remote IP
connection to a set of windows-based programs generally referred
to as the WCC III programs. This WCC III – MCD also has
hardware (WCCIII MCOMM board) that interfaces to a RS-485
communications loop that connects to SAT III type controllers for
building automation controls.
Watchdog Circuit/Power Fail
If the BACKTASK.exe program is not running on the WCCIII
- MCD, there is a watchdog circuit that will restart the WCCIII
– MCD. This watchdog circuit may interfere with the installation
of new BACKTASK.exe software. There is a way to disable this
watchdog circuit. Please contact WattMaster Controls for further
information on temporarily disabling this watchdog circuit. In
addition to this watchdog circuit, there is a small wall wart 24vac
transformer that must be connected to 120VAC or else the WCCIII
- MCD will restart every two minutes. This is part of the power fail
design circuit of the WCC III – MCD. This transformer is meant to
be plugged into a (NON – UPS) 120VAC outlet. The power cord
for the WCC III – MCD is to be connected to a dedicated UPS
(Uninterruptible Power Supply) outlet so that the MCD will keep
running during a minor power outage. The Cable/DSL modem/
router should also be plugged into one of these dedicated UPS
(Uninterruptible Power Supply) outlets.
MCD-Menu Program Overview
WattMaster Controls has developed a simple setup installation
program for the Linux command line interface, and this program
is called mcd-menu. Prior knowledge of Linux is not required, but
would be helpful. This mcd-menu program has eleven subprograms
incorporated into it that will allow for the following operations to
be preformed:
•
The setup of the Network IP Confi guration of the
WCC III – MCD network card interface
•
Copying of the BackTask specifi c data fi les to the root
of the USB Drive
•
Restoring of the BackTask specifi c data fi les from the
root of the USB Drive
•
The resetting of the WCC III - MCD IP address back
to the WattMaster factory Default IP Address settings
•
The resetting of the WCC III - MCD DNS settings
back to the WattMaster factory default DNS settings
•
The restarting of the 2 by 20 line LCD Driver that is
located on the front of the WCC III - MCD
•
The restarting of the 2 by 20 line LCD Display that is
located on the front of the WCC III - MCD
•
The testing of the Internet Connection, from the WCC
III - MCD to the internet
•
The testing of DNS Settings, from the WCCIII - MCD
to the internet
•
The shutdown of the WCC III - MCD – properly
closing down
•
The shutdown and restart of the WCC III - MCD
The Webmin access method can also accomplish all of these same
tasks, but is a little bit harder to use and is meant to be more of an
“off site” management tool for the WCC III - MCD. The mcd-
menu program is meant to be used as the initial IP setting tool and
BACKTASK data fi le loading tool for the WCC III - MCD. For
this a monitor and keyboard needs to be connected temporarily
just for the initial IP setup and BACKTASK data fi le loading.
