Operation RIA45
14 Endress+Hauser
6 Operation
The easy operating concept of the device makes it possible for users to commission the
device for many applications without a printed set of Operating Instructions.
The FieldCare operating software is a quick and convenient way of configuring the device.
Brief explanatory (help) texts provide additional information on individual parameters.
6.1 Operating elements
6.1.1 Local operation at the device
The device is operated by means of the three keys integrated in the front part of the device
• Open the configuration menu
• Confirm an entry
• Select a parameter or submenu offered in the menu
Within the configuration menu:
• Scroll step-by-step through the parameters/menu items/characters offered
• Change the value of the selected parameter (increase or decrease)
Outside the configuration menu:
Display enabled and calculated channels, as well as min. and max. values for all the active
channels.
You can always exit items/submenus at the end of the menu by selecting "x Back".
Leave the setup directly without saving the changes by pressing the ‘-’ and ‘+’ keys
simultaneously for > 3 s.
6.1.2 Configuration via interface & FieldCare Device Setup PC
configuration software
LCAUTION
Undefined switching of outputs and relays possible while configuring with FieldCare
‣Do not configure during running process.
To configure the device with the FieldCare Device Setup software, connect the device to
your PC. You need a special interface adapter for this purpose, e.g. the Commubox
FXA291.
Installing the communication DTM in FieldCare
Before the configuration of the device can be done, FieldCare Device Setup must be
installed on your PC. The installation instructions can be found in the FieldCare
instructions.
Subsequently, install the FieldCare device driver according to the following instructions:
1. Firstly, install the device driver "CDI DTMlibrary" in FieldCare. It can be found under
"Endress+Hauser Device DTMs → Service / Specific → CDI" in FieldCare.
2. Then the DTM catalog must be updated. Add the new installed DTMs to the DTM
catalog.

RIA45 Operation
Endress+Hauser 15
Installing the Windows driver for the TXU10/FXA291
To install the Windows driver Administrator rights are required. Proceed as follows:
1. Connect the device to the PC using the TXU10/FXA291 interface adapter.
 A new device is detected and the Windows installation assistant opens.
2. In the installation assistant, do not carry out the automatic search for a driver. For
this, choose "No, not this time" and click "Next".
3. In the subsequent window, choose "Install from a list or specific location" and click
"Next".
4. In the next window, click "Browse" and select the directory where the driver for the
TXU10/FXA291 adapter is located.
 The driver is installed.
5. Finish the installation by clicking "Finish".
6. A further device is detected and the Windows installation assistant opens once more.
Again, choose "No, not this time" and click "Next".
7. In the subsequent window, choose "Install from a list or specific location" and click
"Next".
8. In the next window, click "Browse" and select the directory where the driver for the
TXU10/FXA291 adapter is located.
 The driver is installed.
9. Finish the installation by clicking "Finish".
The installation of the Windows driver for the interface adapter is now complete. Which
COM-Port has been assigned for the adapter can be seen in the Windows device manager.
Establishing the connection
To establish the connection with FieldCare, proceed as follows:
1. Firstly, edit the connection macro. For this, start a new project and in the window
displayed, click with the right mouse button on the symbol for "Service (CDI) FXA291"
and choose "Edit".
2. In the following window, next to "Serial interface", select the COM port which has
been assigned during the installation of the Windows driver for the TXU10/FXA291
adapter.
 The macro is now configured. Complete configuration by clicking "Finish".
3. Start the macro "Service (CDI) FXA291" by double-clicking it and confirm the
subsequent query with "Yes".
 A connected device is searched and the suitable DTM is automatically opened.
The configuration starts.
To then configure the device itself, follow these Operating Instructions for the device. The
entire Setup menu, i.e. all the parameters listed in these Operating Instructions, can also
be found in the FieldCare Device Setup.
In general, it is possible to overwrite parameters with the FieldCare PC software and
the appropriate device DTM even if access protection is active.
If access protection by means of a code should be extended to the software, this
function should be activated in the extended device setup.
For this purpose, select: Menu → Setup / Expert → System → Overfill protect →
German WHG and confirm.
