Configuring a TDY
One of the benefits of the TDY transmitter is its easy-
to-use PC program; there are no internal or external
controls to adjust or settings to change. All operating
parameters are set using the PC program included
with each shipment. These settings are “downloaded”
in the form of a Configuration File into nonvolatile unit
memory over a connection between the PC’s serial
(COM) port (or USB port when using cable
804-030-26) and a COM port on the transmitter.
This section of the manual contains instructions for
configuring the TDY:
• Installing the Software
• Saving the Default Configuration
(Keeping What You’ve Got Safe)
• Selecting Input Type, Wiring Configuration,
etc.
• Scaling the Input/Setting Reverse Output
• Setting the Display
• Scaling the Output
• Trimming the Input
• Trimming the Output
• Setting Miscellaneous Parameters,
including Readout Engineering Units in °F
or °C, Input Filtering, Upscale or Downscale
Drive on Sensor Failure, and Broken Input
Wire Detection
• Setting Output Damping, Using the Loop Test
• Creating Custom Linearization Tables
• Managing Configuration Files
What is First
First, it is necessary to install the TDY Configuration
Program on a PC. Once the program is loaded and
running, nearly all of the operating parameters for the
connected transmitter are shown on a single screen
(see Figure 3). This makes it easy to determine which
aspects of transmitter operation need to be changed
to suit the application requirements.
What is Next
Once the Configuration Program is installed on the
PC, the TDY can be connected to equipment to
simulate input and monitor output, and with the PC
program, the user can view and/or change its
operating parameters.
No Transmitter Needed
It is not necessary to connect the TDY to a PC to
create Configuration Files. The Configuration
Program can be run without connecting a transmitter,
and
most
operating parameters can be set without
benefit of input from a sensor or from a transmitter.
This makes it easy to create a set of operating
parameters, save them to disk, and download them to
one or more transmitters at a later time.
Note, however, that
not all parameters can be set
without a transmitter. In some cases, a source of
input is also required.
The TDY must be connected to the PC in order to:
• Trim Input
• Trim Output
• Assign a Tag
• Perform a Loop Test
• Receive (via download) a Configuration File
And, perhaps most importantly...
• SAVE THE CONFIGURATION FILE ALREADY IN
THE TRANSMITTER’S MEMORY (refer to
“Keeping What You’ve Got Safe—Using ‘Get
Setup’”
)
