1 EQUIPMENT DESCRIPTION
T he HART
®
4-20 mA VHC10-P converter is a member of the Vivace Process Instruments product family, designed to
create up to two additional 4-20 mA current channels, aiding analog monitoring in devices that do not have this
feature (valve positioners, for example) or that need this monitoring in more than one variable.
The converter can be powered by voltages between 12 and 45 Vdc, generating up to two 4-20 mA current channels
(according to NAMUR NE43 standard). Its function is to monitor any user-configured variables of other HART
®
equipment (regardless of its version) and output them through the current channels.
Its configuration uses the HART
®
7 communication protocol, already established as the most used in the industrial
automation world for configuration, calibration, monitoring and diagnostics.
The converter configuration is carried out at the beginning of its operating cycle, with the converter in "slave" mode,
being completed by the user by changing the use mode to "master". Configurations can be performed using a
HART
®
configurator or tools based on EDDL
®
or FDT/DTM
®
.
Prioritizing high performance and robustness, it was designed with the latest technologies in electronic components
and materials, ensuring long-term reliability for systems of any scale.
1.1. BLOC DIAGRAM
The modularization of the converter components is described in the following block diagram.
Figure 1.1 –VHC10-P block diagram.
The DC source input block is responsible for powering all circuits. The current control block is composed of a circuit
that transforms the digital values generated by the microcontroller into 4-20 mA currents, proportional to the
variables monitored by the converter.
The HART
®
modem block interfaces the microcontroller signals with the HART
®
line connected to the monitored
equipment.
Finally, the CPU block can be related to the converter's brain, where all the time controls, switching between HART
®
Master/Slave state machines take place, in addition to routines common to transmitters, such as configuration,
calibration and generation of output values digital for the currents, proportional to the monitored variables.

The equipment model and specifications are indicated on the identification labels located on the front
and side of the enclosure. Check that the specifications and model provided are as specified for your
application and requirements.
The electrical installation of the VHC10-P converter must be carried out after fixing it to the DIN rail. The HART
channel must be connected between the converter and the equipment to be monitored and, only later, connect the
supplies to the converter's current channels.
Converter connections are shown in figure 2.1 (2-channel model).
Note at the top, that the converter is powered by a voltage source (12 to 45 Vdc - OUT1) and its input is polarized,
with the positive terminal being number 1 (on the left) and the negative terminal being the number 2 (on the right).
Terminals 3 and 4 must be powered by another voltage source (polarized input) to enable the output of current
OUT2 for the two-channel model.

At the bottom user can find the HART
®
communication terminals (terminals 5 and 6). In this case, there is no polarity.
Terminal 7 must be left open and terminal 8 can be optionally grounded.
The VHC10-P can monitor variables from HART
®
devices powered by voltage (transmitters) or by current (valve
positioners). The communication connections with these devices are represented, respectively, in figures 2.2 and
2.3, below.
In the case of monitoring a transmitter equipment (figure 1.4), a load of 250 ohms is required to enable the
modulation of the current in the HART
®
standard, in series with the transmitter's supply voltage.
User must use an independent voltage source to power the transmitter, different from the source(s) of the VHC10-P
converter, since the converter output currents will indicate the variables read from the transmitter, as indicated in the
figures.
Communication terminals 5 and 6 of the converter must be connected over the 250 ohm load, where there is
modulation of the HART
®
signal in the current.

In the case of monitoring a valve positioner (figure 2.3), a 250 ohm load is not required for communication, as the
valve positioner is powered by a 4-20 mA current input.
Note that in this example only one output is used to monitor the valve position by reading the positioner's PV
variable.
Communication terminals 5 and 6 of the converter must be connected directly to the current supply input of the

3 CONFIGURATION
3.1. JUMPERS FOR LOCAL ADJUST AND WRITE PROTECTION
In addition to the software write protection function, using a
configurator, user can change the hardware protection (figure 3.1),
in order to ensure that no user can remotely modify their settings.
Software write protection does not disable hardware protection and
vice versa. For write protection to be disabled, both must be
disabled.

PROGRAMMER
The configuration of the equipment can be performed using a programmer compatible with HART
®
technology.
Vivace offers VCI10 HART
®
line interfaces (USB or Bluetooth) as a solution for configuration and monitoring of
HART
®
line equipment.
Figure 3.2 exemplifies the use of the USB interface with a personal computer that has HART
®
configurator software
installed, for communication with a valve positioner.
A 250Ωresistor must be used in series with the equipment power supply when the equipment to be monitored is
powered via voltage, if the source does not have this load internally, to enable HART
®
communication over the 4-20
mA current. Vivace interfaces already have this load internally.

3.3. CONFIGURATION PARAMETERS
Parameters are available for user configuration through a HART
®
programmer. In addition to the parameters inherent
to the protocol, there are some basic parameters to be configured before starting the converter: the address of the
equipment to be monitored, the codes of the variables to be monitored, units and working ranges for calculating the
currents.
The parameters inherent to the protocol concern the converter itself, basically dealing with its identification (Tag,
Description, Date, Address) and calibration of the currents to be used as output signals of the monitored variables.
For more details on each of these parameters and where to configure them, see section 3.5.
CONFIGURATION WINDOW
VHC10-P normally works as a "master" in order to monitor the "slave" equipment and generate currents proportional
to the monitored variables. So, converter will not receive HART
®
commands from another master, making it
impossible to configure it when in this mode.
To configure it, the user must follow the procedure below.
a. Reset VHC10-P converter
The converter will wait for configuration commands to be received. If no command is sent within 30 seconds", the
"master mode will be enabled automatically.
b. Localize the conversor
Using a HART
®
configurator, poll device at address one (1) – or at the address modified by user user.
c. Change mode to Configuration
In the "Settings" directory, change the converter mode to "Configuration". From this moment on, the user will be able
to make any configuration with peace of mind, without the converter going back to the "master" mode.
d. Configure addresses, variables and ranges
User must verify that the address of the "slave" equipment, the codes of the variables to be monitored, working
ranges and units are correct.
The variables to be monitored can be chosen among the dynamic variables (PV, SV, TV or QV) or by a variable-
specific code index (check the indexes available in the monitored product manual).
e. Change mode to Monitoring
In the "Settings" directory, change the converter mode to "Monitoring" (or "Enable Master Mode", according to the
configurator used). From this moment on, the user will no longer be able to configure the converter and it will work in
"master" mode.
CAUTION
As VHC10-P converter will be connected on the same HART
®
line as the equipment monitored, its default
address is one (1). Therefore, when using the HART
®
configurator for configuration, this address must be
entered by the user in the 'Polling Address' field.
CAUTION
If the converter enters monitoring mode and the user wants to change any configuration, the procedure
must be restarted.
NOT
E
Vivace configuration tools such as VMT-HART and converter DTM already send this command
automatically. In this case, the user can go straight to item d..

IDENTIFYING SLAVE DEVICE
After installing the converter on the HART
®
network, user must configure the address of the equipment to be
monitored (0 to 15, for HART
®
6 or earlier; 0 to 63, for HART
®
7) and the variable codes of this equipment to be
converted to 4-20 mA current.
In the case of variables, user can choose between main dynamics (PV, SV, TV or QV) or manually enter the code of
the desired variable, if it is not one of the four above.
With these configurations completed, user will be able to activate the monitoring of the slave equipment ('Enable
Master Mode') in the “Configuration” menu, when the converter will start to try to identify the slave equipment at the
configured address.
In case of success, the monitoring of the configured variables will start automatically, generating the 4-20 mA output
currents proportional to the values configured in the parameters of the respective working ranges and current
calibrations (HART
®
standard).
CONFIGURATION EXAMPLE:
Converter: Address 1
Slave Device: Address 0
Monitored Variable 1: PV%
Variable 1 Unit: %
Variable 1 Range: 0% to 100%
Monitored Variable 2: SV
Variable 2 Unit: °C
