RIA15 Product description
Endress+Hauser 9
3 Product description
3.1 Function
Process display unit RIA15 is integrated in the 4 to 20 mA/HART® loop and transmits the
measuring signal in digital form. The process display unit does not require an external
power supply. It is powered directly from the current loop.
The device meets the requirements of the HART® Communication Protocol Specificaions
and can be used with devices with HART® Revision ≥ 5.0.
3.2 Operating modes
The process display unit can be used in two different operating modes:
4 to 20 mA mode:
In this operating mode, the process display unit is incorporated into the 4 to 20 mA
current loop and measures the transmitted current. The device shows this value in digital
form on the 5-digit LCD display. In addition, the associated dimension and a bar graph can
be scaled and displayed.
HART mode:
The device functions as a display unit even when operating with a HART® sensor/actor. In
this case, the display is also powered from the current loop.
The process display unit can choose to function as a primary master or secondary master
(default) in the HART® loop. The master type is configured in the SETUP – MTYPE menu.
When it functions as a master, the device can read process values from the measuring
device and display them. HART® communication operates on the principle of master/slave.
As a general rule, the sensor/actor is a slave and only transmits information if a request
has been made by the master.
A HART® loop can have a maximum of two HART® masters at any one time. A distinction
is made between primary (e.g. the control system) and secondary master (e.g. handheld
terminal for on-site operation of the measuring devices) for these HART® masters. The two
masters in the loop/in the network cannot be masters of the same type, e.g. they cannot
be two "secondary masters".
If a third HART® master is added to the network, one of the other masters must be
disabled; otherwise a collision occurs in the network.
If the process display unit is operating as "secondary master" and another "secondary
master", e.g. a handheld device, is added to the network, the device interrupts HART®
communication as soon as it detects that there is another "secondary master". The display
alternates between error message C970 "Multi master collision" and "- - -". A measured
value is not displayed in this case. The device leaves the HART® loop for 30 seconds and
tries to re-establish HART® communication once again. Once the additional "secondary
master" is removed from the network, the device continues communication and displays
the measured values of the sensor/actor once more.
Please note that if two process display units are to be used in a multidrop connection,
one device must be configured as "primary master" and the other as "secondary master"
to prevent a master collision.
In HART mode, the process display unit can show up to four device variables of a
multivariable measuring device. These variables are referred to as the Primary Variable
(PV), Secondary Variable (SV), Tertiary Variable (TV) and Quaternary Variable (QV). These
variables are placeholders for measured values that can be called up using HART®
communication.

Product description RIA15
10 Endress+Hauser
For a flowmeter, such as the Promass, these four values can be as follows:
• Primary process variable (PV) →Mass flow
• Secondary process variable (SV) → Totalizer 1
• Third process variable (TV) → Density
• Fourth process variable (QV) → Temperature
For a level meter, such as the Levelflex FMP5x, these four values can be as follows:
• Level measurement:
Primary process variable (PV) → Level linearized
Interface measurement:
Primary process variable (PV) → Interface
• Level measurement:
Secondary process variable (SV) → Distance
Interface measurement:
Secondary process variable (SV) → Level linearized
• Level measurement:
Third process variable (TV) → Absolute echo amplitude
Interface measurement:
Third process variable (TV) → Upper interface thickness
• Level measurement:
Fourth process variable (QV) → Relative echo amplitude
Interface measurement:
Fourth process variable (QV) → Relative interface amplitude
The HART® section at the end of these Operating Instructions provides further examples of
these four device variables for multivariable measuring devices (→  42).
Please refer to the Operating Instructions for each device for details on the variables
that are set as default on the sensor/actor and how they can be changed.
The process display unit can show each of these values. The individual values must be
activated in the SETUP – HART1 to HART4 menu for this purpose. The individual
parameters are assigned to fixed process variables in the RIA15 in this case:
HART1 = PV
HART2 = SV
HART3 = TV
HART4 = QV
For example, if the PV and TV are to be displayed on the process display unit, HART1 and
HART3 must be activated.
The values can either be shown alternately on the process display unit or one value is
displayed continuously and the other values are only shown by pressing '+' or '–'. This can
be configured in the "EXPRT" – "SYSTM" – "TOGTM" menu.
3.3 Input channels
The process display unit has one analog 4 to 20 mA input. In "HART" operating mode, this
channel can be used for measuring and displaying HART® values for a connected sensor/
actor. In this case, a HART® device can be directly connected to the process display unit in a
point-to-point connection or the process display unit can be incorporated in a HART®
multidrop network.
