COMMUNICATIONS SETUP
Stop Bits - A bit(s) which signals the end of a
unit of transmission on a serial line. A pull down
menu is provided to select from the following:
•
1
•
2
Parity - In communications, parity checking
refers to the use of parity bits
to check that data
has been transmitted accurately. The parity bit is
added to every 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 communications. A pull down menu is provided
to select from the following:
•
None
•
Even
•
Odd
RS-485 Connection - This defines to the
Quantum™ LX the type of hardware that it will be
communicating to. This selection does not apply
to Com-3, as it is dedicated to RS-232
communications only. A pull down menu is
provided for Com-1 and Com-2 to select from the
following:
•
Yes – This port will be connected to an
RS-485 device.
•
No – This port will not be connected to
an RS-485 device. It will be using RS-
422. If Com-2 is setup through jumper
11 to use RS-232, then this setting will
be ignored.
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
recognized protocols:
•
None
•
Frick
•
ModBus ASCII
•
ModBus RTU
•
AB DF1 Full Duplex
•
AB DF1 Half Duplex
Map File - Because the addressing scheme
between the Quantum™ version 2.0x and earlier
software and the Quantum™ LX version 3.0x and
later software is not the same, this file was
created. The map file is a conversion utility that
can be used to allow a communications
application that was previously written by the
user under the Quantum™ version 2.0x and
earlier to function properly with the Quantum™
LX by redirecting the old addresses to the new
addresses (see the section entitled Using the
MAP file for additional information). A pull down
menu is provided to select from the following:
•
No - Do not use map file, the user is
either not going to be using external
communications, or they will be writing
the communication application based
upon the Quantum™ LX addresses.
•
Yes - The user has an application that
was previously written for the
Quantum™ version 2.0x 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
communications are occurring.
•
Failed - Loss of communications, a
shutdown message will be generated.
Redetect IO Comms - Select this key to detect all
connected Analog and Digital boards. If a board has
been removed, a communication error shutdown will
be issued 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 file to be downloaded
from the Quantum™ LX into the USB memory.
Upload MapFile.txt to Quantum™ LX – After the
user has modified the MapFile.txt file to suit their
needs, pressing this key will cause the file to be
uploaded from the USB memory back into the
Quantum™ LX.
USING THE MAP FILE
The MAP file is simply a text file (Mapfile.txt), which
can be downloaded from the Quantum™ panel. The
file can be used in its original format, which contains a
limited number of addresses, or may be modified by
the user, to incorporate additional addresses.
Downloading The Map File From The Quantum™
To download the map file 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 present a dialog box allowing the user select
a location on their computer for the map file to be
stored. (NOTE: This operation is not intended to
