As more and more environments become wired for the
Internet, we’ve developed scales to match. You can now
monitor and control your Arlyn Scales over your local
network. Simply plug the scale into the network and connect
to it using our Remote Indicator software. Weights can be
recorded, sorted, grouped and analyzed from your workstation
PC. It is also possible to set up your network so that you
can access the scale from anywhere in the world over the
Internet. We also offer a Wireless Ethernet option.
The Setpoint output provides some simple Batching and PLC
type functions. You may set up to 8 target weights at a
time, and use these targets to turn other equipment on and
off. Feeders, mixers, motors, valves, solenoids and other
devices may be controlled using solid-state relays that are
operated by the setpoint outputs. The most common use is
automated filling and mixing operations. Through the use of
the setup menu, formulas can be input to control how those
output lines behave based on the weight applied to the scale
platform. Many different formulas may be saved in the scale
memory, and recalled when needed.
USB (Universal Serial Bus) is the most common interface
on today’s PCs. This option, in combination with Arlyn’s
Remote Software allows scale data to be sent to an Excel
spreadsheet or Access database file on the PC. The PC can
also control the scale’s operation. A utility is also
available to send weight data from the scale directly into
any Windows application software.
RS-232 is a standard communications protocol used mainly
to transmit data from one piece of computerized equipment to
another. In the digital scale world, RS232 is used to
communicate with printers, programmable logic controllers
and computers. Arlyn’s RS232 Option is a bi-directional
interface that allows the Scale Indicator to not only send
data, but also receive commands from computers and the like.
This allows full remote capability. Consult our
Options Manual for full details.
Included in the scale’s operating software is a print frame
definition editor that allows for customized outputs like
complex printed labels.
Need a robust, long distance network protocol to connect
several scales and a personal computer? RS-485 is another
communication system built into Arlyn Scales. It differs
from RS-232 and USB by the distance over which it can
successfully transmit and recieve - 4000 feet. RS-485 is a
“multidrop” protocol, meaning that several scales can share
a signle line, forming a network. We also sell an RS-485 to
USB interface allowing you to log data and directly control
up to ten scales from a single PC.
This is an add-on option to RS232 that gives it the
capability to add time (12 or 24hr format), day of week and
date to any print frame. The clock is set through the
indicators menu system. An internal lithium battery will
keep time for up to ten years, even if the power is removed
from the scale.
Analog Output is used to communicate with programmable
logic controllers and chart recorders. Through the setup
menu, full configuration is provided allowing you to set the
start and ending currents or voltages. Analog Output is
available in two configurations, Current and Voltage output.
Voltage Output = 0 to 5VDC scalable
Current Output = 4 to 20ma scalable
An internal six cell, rechargeable NiMH battery Pack and
its associated peak detect charging circuit can be installed
in the scale indicator for portable use. The scale can
operate for over twenty hours on a single four hour peak
Many of our customers need to record weights from our scales. Our datalogging option enables your scale to record a weight along with time, data, group and item information. Data is saved on USB drive that can be removed from the scale and read on a personal computer using Microsoft Excel.
