data unit (typically seven or eight data bits) that
are transmitted. The parity bit for each unit is set
so that all bytes have either an odd number or
an even number of set bits. Parity checking is the
most basic form of error detection in communica-
tions. A pull down menu is provided to select from
the following:
• None
• Even
• Odd
Protocol - A protocol is the special set of rules
that each end of a communications connection
use when they communicate. A pull down menu is
provided to select from the following Frick recog-
nized protocols:
• None
• Frick
• ModBus ASCII
• ModBus RTU
• AB DF1 Full Duplex
• AB DF1 Half Duplex
• DBS Motor Starter
• Vyper
Map File - Because the addressing scheme between
the Quantum™ version 3.0x and earlier software and
the Quantum™ LX version 3.1x and later software is
not the same, this le was created. The map le is a
conversion utility that can be used to allow a commu-
nications application that was previously written by the
user to function properly with the Quantum™ LX by re-
directing the old addresses to the new addresses (see
the section entitled Using the MAP le for additional
information). A pull down menu is provided to select
from the following:
• No - Do not use map le. The user is either
not going to be using external communica-
tions, or they will be writing the communi-
cation application based upon Quantum™ LX
addresses.
• Yes - The user has an application that was
previously written for the Quantum™ version
3.0x or earlier, and they want to utilize the
same code for the Quantum™ LX.
I/O Comms - A status indicator is provided to show
the current state of the internal communications of the
I/O boards. The possible displayed states are:
• Off - Loss of or intermittent communications
failures to the internal Quantum™ LX I/O
boards.
• Active - Indicates that normal I/O communi-
cations are occurring.
• Failed - Loss of communications, a shutdown
message will be generated.
Redetect IO Comms - Select this key to detect all con-
nected Analog and Digital boards. If a board has been
removed, a communication error shutdown will be is-
sued until this key is selected. Reference the About
screen to view what has been detected.
Two keys are located at the bottom right hand side of the
screen. The following describes there function:
Download MapFile.txt from Quantum™ LX – With
a USB memory stick installed on the LX, pressing this
key will cause the MapFile.txt le to be downloaded
from the Quantum™ LX into the USB memory.
Upload MapFile.txt to Quantum™ LX – After the user
has modied the MapFile.txt le to suit their needs,
pressing this key will cause the le to be uploaded
from the USB memory back into the Quantum™ LX.
USING THE MAP FILE
The MAP le is simply a text le (map.txt), which can
be downloaded from the Quantum™ panel. The le
can be used in its original format, which contains a
limited number of addresses, or may be modied by
the user, to incorporate additional addresses.
Downloading The Map File From The Quantum™ LX
Through a Web Browser:
To download the map le from the Quantum™ LX
controller, click the Download button. A new box
will appear with a link labeled MapFile.txt. Right
click on the link, and select Save Link Target As…
from the menu. The web browser will then pres-
ent a dialog box allowing the user select a location
on their computer for the map le to be stored.
(NOTE: This operation is not intended to be per-
formed from the Operator Interface Panel. In-
stead, a desktop computer should be used to ac-
cess the Evaporator controller via a web browser).
Downloading the MAP File From the Panel Using a
USB Memory Stick:
Two keys are located at the bottom right side of
the screen. The following describes there func-
tion:
Download MapFile.txt from Quantum™ LX
– With a USB memory stick installed on the
LX, pressing this key will cause the MapFile.
txt le to be downloaded from the Quan-
tum™ LX into the USB memory.
Upload MapFile.txt to Quantum™ LX –
After the user has modied the MapFile.txt
le to suit their needs, pressing this key will
cause the le to be uploaded from the USB
memory back into the Quantum™ LX.
