3.3 Additional IHP24 FF-Fieldbus Menu Function
Internally in IHP24 there is a hardware Foundation Fieldbus module. This module communicates
with the rest of the hardware in IHP24 via a local Modbus interface. This interface needs to run at a
fixed setup ID = 1, Baud rate = 38400, Parity = Even, Stop bits = 1. The communication settings
should always be set to these values.
It is important to set the Baud rate after an “Advanced Reset” of the IHP24.

4.2 FF - Function blocks used in Default Setting.
Analogue Input (AI)
Analog input function block, used to receive input data from the transducer blocks (MTB). Other
function blocks can then read the value from the “OUT” port.
In the Default setting:
The “OUT” contains the actual position signal from the Val Controls Device. Values 0.00 to
100.00%
Configuration
If you want to change the sensor input just change the CHANNEL register in the AI Block.

Analogue Output (AO)
Analog output function block, used to transmit output data to transducer block, acting on the
physical device.
In the Default setting:
In “Cascade Mode” the Val Controls Device gets its SP ( Setpoint ) from the “CAS_IN” Input.
Values of the “CAS_IN” should be in the range from “0.00% - 100.00%”
“OUT” contains the same value as “CAS_IN”

Fail position in Cascade Mode
If the Val Controls Device receives the status bad from the fieldbus, the device goes to its fail
position. The fail position is determined depending on configuration.
Example showing what will happen on the AO.OUT when one of the following errors occurs.
Fault Causes
•AO.CAS_IN.STATUS signal has status BAD
•Connection to SPUR is broken
Configuration
•AO.IO_OPTS, can be set to “0” (Disabled) or “Fault state to value”
•AO.FSTATE_VAL, the fail position 0.0% - 100.0%
Control Signal
•AO.CAS_IN –In cascade Mode

5Appendix –NI-FBUS Configurator Tool
5.1 DD File
NI-FBUS Configurator Rev 4 is a tool that can be used to configure the Fieldbus Interface used by
the Val Controls Device.
First you should be sure that the interface is installed in NI-FBUS.
5.2 Import DD Files
In windows
Select [National Instruments / NI-FBUS / Utilities / Interface Configuration Utility]
•If the Interface Configuration Utility will not start, stop the NI-FBUS process.
In windows go to “Task Manager”, and end the “nifb.exe” process.
On the start-up window
•Press Import DD/CFF
•Browse the location for the files, open 000105, open 1001, open 0101.ffo
•Press Ok, .. the DD files is imported successfully
•Browse the location for the files, open 000105, open 1001, open 010101.cff
•Press Ok, .. the DD files is imported successfully
Now start the NI-FBUS configurator
Select [National Instruments / NI-FBUS / NI-FBUS Configurator]
Now NI-FBUS is configured to recognise the Val Controls Fieldbus Device.
5.3 Upload data to NI-FBUS from the device.
First start the NI-FBUS Configurator if not already started. If the application dos not start, check
that to pc is connected to the Fieldbus Network.
In the network there should be a “ValControls” device.
•Click on ‘Device Tag Name’ in the tree window.
•In the menu select ‘Configure’.
•Choose ‘Upload Configuration.’
•Press ‘Yes’
•.. now its uploading data from the device to NI-FBUS Configurator.

5.4 Changing Node ID from NI-FBUS
If you need to change the Fieldbus Node ID address then you should do it now.
•Click on ‘ValControls’ in the tree window.
•In the menu select ‘ValControls”.
•Choose ‘Set Address’.
•Press ‘Yes’ if you get a warning
•Now you can set the Address in between 17 –36 and 223 - 247
5.5 Modifying Device Tag name
If the default tag names “ValControls” conflicts with the other tag names in the network, they can
be modified with the NI-FBUS tool.
5.6 Modifying Block Tags names
If the default tag names “AI” .. “AO” conflicts with the other tag names in the network, they can be
modified with the NI-FBUS tool.
5.7 Factory Reset of the device.
Do not make a factory reset of the device, since it will reset all parameters in the MTB transducer
block and all TAG names and Node ID address.
