[RS-485 Communications] - (Available for Comms1 and
Comms 2 only). This pull down box allows the user to se-
lect whether or not the communications will be through
RS-485 hardware protocol or not. A drop down menu is
provided to select from the following:
• Yes
• No
[Protocol] - A protocol is the special set of rules that each
end of a communications connection use when they com-
municate. A drop 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
[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 communications or intermittent
communications failures to the internal Quan-
tum™ LX I/O boards.
• Active - Indicates that normal I/O communica-
tions 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 re-
moved, a communication error shutdown will be issued
until this key is selected. Reference the About screen to
view what has been detected.
[Use Map File] - Because the addressing scheme between
earlier Quantum™ version software and the Quantum™
LX version 3.0x and later software is not the same, this
utility was created. The map le is a conversion utility that
can be used to allow a communications application that
was previously written by the user under the Quantum™
version 2.3x and earlier to function properly with the LX
by redirecting the old addresses to the new LX addresses.
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 communications, or
they will be writing the communication applica-
tion based upon the LX addresses.
• Yes - The user has an application that was previ-
ously written for the Quantum™ version 2.3x or
earlier, and they want to utilize the same code
for the LX.
Two keys are located at the bottom right hand side of the
screen. The following describes their 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 modied the MapFile.txt le to suit their
needs, pressing this key will cause the le to be up-
loaded from the USB memory back into the Quan-
tum™ LX.
