SECTION 1 — INTRODUCTION
The Remote Operations Controllers (ROCs) and FloBoss units use standard Highway Addressable
Remote Transducer (HART ® ) Protocol commands to request and write parameters to a HART Slave device. The HART Protocol relies on the Bell 202 Frequency Shift Keying (FSK) standard to superimpose digital signals at a low level on top of the 4 to 20mA. The low-level FSK sine-wave signal transmits digitally. The HART Protocol allows both analog and digital communication signals to be transmitted simultaneously on the same wiring allowing two-way field communications from the
Host to the HART device. Process Variable and control signal information may be transmitted using the 4 to 20mA while additional measurements, device configuration, parameters, and calibration travel over the digital channel.

1.3 HART INTERFACE CARDS AND HART INTERFACE MODULES
The ROC or FloBoss and HART devices create a Host/Slave network. The ROC or FloBoss is the Host and each HART device is a Slave. There are two ways to send and receive HART messages between a
ROC and HART devices, depending on the type of ROC/FloBoss and HART interface being used.
HART Interface Card — The way first uses one HART Interface Card installed in a:
♦
ROC306 or ROC312 with a ROCPAC, firmware version 1.10.
♦
ROC306 or ROC312 with a FlashPAC, firmware version 2.0 or 2.1.
HART Interface Modules — The second way uses one or more HART Interface Modules (sometimes called HART I/O Modules or HART Modules) installed in a:
♦
ROC312 with a ROCPAC, firmware version 1.10.
♦
ROC364 with a ROCPAC, firmware version 1.70.
♦
ROC312 or ROC364 with a FlashPAC, firmware version 2.0 or 2.1.
♦
FloBoss 407 with firmware version 1.04 or 1.06.
NOTE
In the case of the ROC312, it is not possible to use both a HART Interface Card and
HART Interface Modules. One or the other must be chosen. Either option requires the correct HART user program to be loaded into the ROC.
NOTE
ROCLINK Configuration Software is required when using a ROC with a
FlashPAC, or a FloBoss 407 with firmware version 1.06. For ROCs with a
ROCPAC or a FloBoss 407 with firmware version 1.04, either the GV101 or the
ROCLINK Configuration Software may be used.
NOTE
In most cases, the FloBoss 407 and ROC300-series units are identical in operation.
Unless otherwise noted, the descriptions and procedures in this manual apply to all
FloBoss and ROC types. In areas where the operation differs, the differences are described.

HART Program User Manual
1.5 OVERVIEW
ROC and FloBoss units use the standard HART protocol commands to request and write parameters to a HART device. HART travels over low signal frequencies (1200 and 2200Hz) which restricts transmissions to 1200 baud rate. When data is transmitted, 1200Hz represents a “1” state and 2200Hz represents a “0” state. Each message passed between a field device (Slave) and the Host includes the
ROC Address and the destination Slave Address of the HART device, Device Status, and series of bytes representing the Commands sent by the Host. HART Host Commands are detailed in Section 6.
The Host transmits a voltage signal and the Slave responds with a current signal.
Each response message received from the HART Slave device contains information used to indicate problems with the device or communication errors. The Command Response or Response Code reports communication problems or problems with the HART Command the Slave received. The Device
Status field displays the specific condition of the HART field device.
When loaded into RAM, a HART program can use the following configuration software for configuring and monitoring HART points and devices.
♦
ROCLINK Configuration Software version 2.0 or 2.1.
♦
GV101 Configuration Software version 1.63.
NOTE
ROCLINK Configuration Software is required when using the HART program in a
ROC with a FlashPAC, or in a FloBoss 407 with firmware version 1.06. For ROCs with a ROCPAC or a FloBoss 407 with firmware version 1.04, either the GV101 or the ROCLINK Configuration Software may be used.
The HART parameters are referenced in the ROC the same as standard point type parameters by Type,
Logical number, and Parameter (TLP). Each input and output has a unique Point Number to identify the input or output. Each I/O Point Type must be individually configured. This allows parameters such as a HART Primary Variable to be assigned as an input to an AGA Flow Calculation, a Process
Variable or Process Value for a PID loop, a variable to display on a Local Display Panel, or a variable for any other ROC function.
Two point types are added to the ROC protocol by a HART program:
♦
Point Type 30 – HART Point Configuration Parameters
♦
Point Type 31 – HART Device Configuration Parameters
Refer to Appendix B for a complete list of the parameters associated with these HART point types.
Rev 3/99 1-5
HART Program User Manual
1.6 HART INTERFACE CARD PROGRAM
The HART Interface Card Program allows a ROC306 or ROC312 with an installed HART Interface
Card to communicate with HART devices. Using HART digital communications, up to four measurements (Dynamic Variables) can be communicated in a single message. Other HART device specific transmitter variables may also be read. The HART Card allows both digital and analog signals through the ROC analog inputs.
Each of the three built-in analog inputs (AIs) on the ROC306/ROC312 can be configured as a HART
Point. Once a built-in analog input is configured as a HART Point, it can communicate either in the point-to-point mode or in the multi-drop mode to HART devices.
In point-to-point mode, digital communications are superimposed on the 4 to 20 milliamp analog signals (which can still measure the Process Variable) through a built-in analog input. This mode allows communications with one HART device per built-in analog input point and maximizes polling speed. In point-to-point mode, all HART field devices have an address of 0.
In multi-drop mode, several HART devices are connected to a single communications line. As many as five HART devices (limited by the total current consumption of the devices) can be connected in parallel to a single built-in analog input. Like the point-to-point mode, digital communications are superimposed on the current signals; however, the analog signal is used only to measure the current consumed by all HART devices in the multi-drop loop. Communications are restricted to digital transmissions as the loop current is fixed at a minimum value and no longer has meaning relative to the process. The digital transmissions contain the values read from the HART device. Multiple field devices may be physically connected (in parallel) to the same pair of wires when installed. When all three built-in analog input channels are used in multi-drop mode and five HART devices are wired to each input channel, a ROC306/ROC312 with a Hart Card can support a maximum of 15 HART devices.
In multi-drop mode, HART field devices have an address of 1 through 15, and each device sets its output current to a fixed value (typically 4 mA). The ROC HART application sends a message to all multi-dropped devices, telling the HART device with a certain tag name to respond. Therefore, the
Address of that HART device must match the Device Tag as defined in the Config HART Point screen.
If the Device Tag of the HART device (typically set by a handheld communicator) does not match the
Device Tag set in the Config Hart Point screen, the HART device will not respond.

HART Program User Manual
1.7 HART INTERFACE MODULE PROGRAM
The HART Interface Module Program allows a ROC312, ROC364, or a FloBoss 407 unit with one or more installed HART Interface Modules to communicate with HART devices. The 4mA to 20mA analog signal is ignored when using a HART Module and communications are limited to digital signals only.
When using a HART module, the HART module polls the HART device and temporarily stores the data in the HART module. The HART User Program polls the HART module and stores the data into the user defined point types. If the HART User Program fails to collect the data from the HART module, the next time the HART module polls the HART device, the data is overwritten in the HART module.
Each HART module contains two channels configured as HART Points. Each HART module channel or point may be configured for point-to-point mode or multi-drop mode.
In point-to-point mode, one HART device is connected to a HART module channel, for a total of two
HART devices per HART module. In this mode, the speed of polling a HART device is maximized.
In multi-drop mode, as many as five HART devices (limited by the total current consumption of the devices) can be connected in parallel to a single HART module channel. Since each HART module has two channels, one module can support as many as ten HART devices.
The maximum number of HART points/devices allowed by the HART module program is 32. Depending on the mode, this may be accomplished with as few as four or as many as six HART modules.
Therefore, although the ROC364 can physically hold more than six HART modules, the program limits it to using six HART modules.

2.3 HART INTERFACE MODULE
The HART Interface Module provides communications between a ROC and other devices using the
HART protocol. The module has its own microprocessor and mounts in the I/O module sockets of a
ROC.
The HART Interface Module communicates digitally to HART devices through the I/O termination blocks associated with the module position. Each HART module contains two separate channels. Each channel polls all HART devices connected to it before the other channel is polled. Each channel can be configured to operate in either the point-to-point mode or the multi-drop mode. In the point-to-point mode, each module channel supports one HART device.
In the multi-drop mode, each channel can support up to five HART devices for a total of ten devices for each module. By using the multi-drop mode with multiple HART modules, up to 32 HART devices
(limited by the software) can be supported by a single ROC. Refer to Figure 2-1.

2.3.2 HART Interface Module Wiring
The HART Interface Module allows the ROC to interface with up to ten HART devices per I/O slot.
The HART Interface Module communicates digitally to HART devices through the I/O termination blocks associated with the module position. The HART module provides “loop source” power (+T) on terminal A and two channels for communications on terminals B and C. The +T power is regulated by a current limit. If the power required by all connected HART devices exceeds 40 milliamps (more than an average of 4 milliamps each), the total number of HART devices must be reduced.
Channel 1 is wired to terminals A and B. Channel 2 is wired to terminals A and C. The HART module polls one channel at a time. If more than one device is connected to a channel in a multi-drop configuration, the module polls all devices on that channel before it polls the second channel. The
HART protocol allows one second per poll for each device, so with five devices per channel the entire poll time for the module would be ten seconds.
In a point-to-point configuration, only one HART device is wired to each HART module channel.
In a multi-drop configuration, two to five HART devices are connected to a channel. In either case,
Rev 3/99 2-11
HART Program User Manual terminal A (+T) is wired in parallel to the positive (+) terminal on all of the HART devices, regardless of the channel to which they are connected.
Channel 1 (terminal B) is wired to the negative (-) terminal of a single HART device, or in parallel to the negative terminals of two to five devices. Likewise, channel 2 (terminal C) is wired to the negative
(-) terminal of a single HART device, or in parallel to the negative terminals of a second group of two
to five devices. Refer to Figure 2-2 and Figure 2-3.

2.3.3 Testing the HART Interface Module
The HART Interface Module provides the source for the HART devices and uses two test procedures to verify correct operation. Use the first procedure to check the integrity of the loop power and the second to verify communications.
2.3.3.1 Verify Integrity of Loop Power Supplied by ROC
Equipment Required: Multimeter
1.
Measure voltage between terminals A and B to verify channel 1.
2.
Measure voltage between terminals A and C to verify channel 2.
The voltage read in both measurements should reflect the value of +T less the voltage drop of the
HART devices. 24 volts indicates an open circuit in the I/O wiring, a defective HART device, or a defective module.
2.3.3.2 Verify Communications
Equipment Required: Dual-trace Oscilloscope
In this test, the HART module and the ROC act as the Host and transmit a polling request to each
HART device. When polled, the HART device responds. In this test, use the oscilloscope to observe the activity on the two HART communication channels. Note that there is normally one second from the start of one request to the start of the next request.
1.
Attach one input probe to terminal B of the HART module and examine the signal for a polling request and response for each HART device connected to this channel.
2.
Attach the other input probe to terminal C and examine the signal for a polling request and response for each HART device connected.
3.
Compare the two traces; signal bursts should not appear on both channels simultaneously.
Keep in mind that each device on one channel is polled before the devices on the other channel are polled. If a channel indicates no response, this could be caused by faulty I/O wiring or a faulty HART device. If the HART module tries to poll both channels simultaneously, this could be caused by a defective module, in which case the module must be replaced.

2.4 HART INTERFACE CARD
The HART Interface Card plugs “piggy-back” on top of a ROC communications card. Refer to Figure
2-4 and Figure 2-5. The HART Card communicates to HART devices through one or more of the three
built-in analog input channels on the ROC. Each of these input channels can be configured to operate in either the point-to-point mode or the multi-drop mode.

In the point-to-point mode, digital communications is superimposed on the 4 to 20 milliamp analog signal (which can still measure the process variable) through a built-in analog input. This mode allows communications with one HART device per fixed analog input point.
2-14 Rev 3/99
HART Program User Manual
In the multi-drop mode, as many as five HART devices can be connected in parallel to a single built-in analog input. Like the point-to-point mode, digital communications are superimposed on the fixed signal (typically 4 mA); however, the analog signal is used only to measure the current consumed by the multi-drop loop. With all three built-in analog input points in the multi-drop mode and five HART devices wired in parallel, the ROC306/312 can support a maximum of fifteen HART devices.
2.4.1 Installing a HART Interface Card
The HART Interface Card package includes one HART Interface Card, one 6-pin header, and a mounting screw. The following items are also required to support the HART Interface Card:
♦
GV101 Configuration Software version 1.63, or ROCLINK Configuration Software version
2.0 or 2.1.
♦
ROC306 or ROC312 main board with part number W48032X0012 revision A or greater.
♦
ROC306/312 with ROCPAC version 1.10, or with FlashPAC version 2.0 or 2.1 (used with
ROCLINK only).
♦
HART Interface User Program, loaded into ROC memory.
♦
A ROC communications card installed and functioning.
To allow a HART Interface Card to be installed, a communications card of any type must already be
the procedure.
CAUTION
Install HART Interface Cards only in areas known to be non-hazardous.

2.4.2 HART Interface Card Wiring
The HART Interface card provides digital, command/response communications with HART devices such as smart transmitters. The HART devices connect to the ROC via one or more of the three built-in analog inputs, and the digital communications are superimposed on the 4 to 20 milliamp current signal.
modes.
From one to five HART devices can be used in the multi-drop mode. In this mode, the fixed current
(typically 4mA) is used only to measure the current consumed by the HART devices. In the point-to-
point mode, only one HART device is connected and the same analog input terminals are used. In this mode, the 4 to 20 milliamp signal can be used for measuring the process variable.
At the analog input, the HART card provides “loop source” power (+T) and the “+” terminal is used to bring the digital signal to the HART card. The +T power is regulated by a current limit.

2.4.3 Testing the HART Interface Card
The HART Interface card provides the source for the HART devices and uses two test procedures to verify correct operation. Use the first procedure to check the integrity of the loop power and the second to verify communications.
2.4.3.1 Verify Integrity of Loop Power
Equipment Required: Multimeter
For each built-in Analog Input being used, measure the voltage between the “T” and “+” terminals.
The voltage read is the voltage drop of the HART device. 24 volts indicates an open circuit in the I/O wiring, a defective HART device, or a defective supply to “T” from the ROC. Any value below the minimum value of 10.5 volts indicates that the HART device is malfunctioning. A typical value should read between the range of 15 to 17 volts.
2-18 Rev 3/99
HART Program User Manual
2.4.3.2 Verify Communications
The HART card and the ROC act as the Host and transmit a polling request to each HART device.
When polled, the device responds. In this test, use the oscilloscope to observe the communications between the HART devices and the HART card.
Equipment Required: Oscilloscope
1.
For each Analog Input channel being used, attach the input probe of the oscilloscope to the “+” terminal.
2.
Verify the channel is active by observing the oscilloscope trace for signs of communications activity. There should be a request and response message burst for each device connected, with one second of time from the start of one request to the start of the next request.
If a channel indicates no response, this may indicate faulty I/O wiring or a faulty device. If a channel shows no polling request (even after ensuring proper configuration), the HART card is defective and must be replaced.

A screen appears that shows the allocation status of all user memory blocks in the upper half of the screen and a list of the User Programs and task status in the lower half. Memory blocks are 16K bytes in length and the individual User Program determines their allocation. The ROC Operating System checks each block for proper allocation and does not permit two different programs to the share same memory block. If you install a user program into memory that already contains another user program, the user program currently installed will be overwritten.
The upper half of the display appears similar to the following:
Block 6000 = Unalloc Block a000 = Unalloc Block c000 = Code 1
Block 6400 = Unalloc Block a400 = Unalloc Block c400 = Code 1
Block 6800 = Unalloc Block a800 = Unalloc Block c800 = Data 1
Block 6c00 = Unalloc Block ac00 = Unalloc Block cc00 = Unalloc
Block 7000 = Unalloc Block b000 = Unalloc Block d000 = Code 2
Block 7400 = Unalloc Block b400 = Unalloc Block d400 = Code 2
Block 7800 = Unalloc Block b800 = Unalloc Block d800 = Data 2
Block 7c00 = Unalloc Block bc00 = Unalloc Block dc00 = Unalloc
3-8 Rev 3/99
HART Program User Manual
For a ROC300-series unit with a ROCPAC, blocks 6000 through bc00 correspond to various RAM modules, and blocks c000 through dc00 correspond to the RAM.
For a ROC300-series unit with a FlashPAC, blocks a000 through bc00 correspond to various RAM in the FlashPAC, and blocks c000 through dc00 correspond to the Flash memory in the FlashPAC.
For the FloBoss 407, blocks 6000 through 7c00 correspond to user RAM in the ROC; blocks a000 through cc00 correspond to Flash memory in the ROC; and blocks d000 through dc00 are reserved for factory use.
The allocation status since the last Warm Start is shown for each memory block as follows:
No RAM — No RAM is installed in this location. When viewing FloBoss 407 memory, No RAM displayed for Flash memory blocks a000 through cc00 means that the memory is unallocated.
Unalloc — No program assigned or no memory installed. The memory is available to install a User
Program.
Code x — Code location for the User Program installed at that memory location.
Data x — Data location for the User Program installed at that memory location.
For more information on viewing the memory allocation of all User Programs loaded in the ROC, refer to Section 8 in the GV101 Configuration Software User Manual.

3.2.3.1 Deleting A User Program From FloBoss 407 Flash Memory
User Programs loaded in the Flash memory (ROM) of a FloBoss 407 are not deleted in the same way
User Programs loaded in RAM would be deleted. Programs loaded in RAM are removed with the
Clear All User Memory selection under User Program Routines in the Utilities menu of GV101. This routine has no effect on User Programs loaded in Flash memory.
NOTE
This procedure is not required when using ROCLINK.
To clear User Programs loaded into Flash memory, you must download a “dummy” User Program
(which contains all zeros) to the targeted blocks of Flash memory. A series of programs,
FBCLR_xx.H00, are supplied with the other HART user program files (see the listing in Table 1-1 at the end of Section 1). When downloaded, the FBCLR program clears out Code in the segment (16
Kbytes) by causing zeros to be written to the first 64 bytes. For example, to clear the A000 memory
Code segment, download the FBCLR_A0.H00 program.
To download an FBCLR program using the GV101 configuration software and to clear Flash memory:
1.
Determine the memory location where the User Program is currently installed and select the clear HART User Program that corresponds to the allocated block of memory. Refer to
Section 3.1.4, Viewing Available Memory, on page 3-5 to view available memory.

To configure HART Points using ROCLINK:
1.
Select the I/O menu in ROCLINK.
2.
Select HART Point.
Rev 3/99
Figure 4-1. Config HART Point Using ROCLINK
4-1
HART Program User Manual
When using a HART Interface Card program, the first line, Config Hart Point 1 of x, shows the current point displayed (1) and the maximum number of points (x). The value for x is fixed at 3 when using the HART Interface Card. When using a HART Interface Card program, the HART Points use the three built-in analog input points (for example, HART Point 1 uses Analog Input Point Number 1).
If you are monitoring or controlling a fast-changing process, it is a good idea to configure the HART
Point into the point-to-point mode and also configure the corresponding Analog Input point to make use of the analog signal.
When using a HART Interface Module program, the first line, Config Hart Point 1 of x, shows the current point displayed (1) and the maximum number of points (x). The value for x is the number of modules multiplied by 2. There are two points for every module installed. If you are monitoring or controlling a fast-changing process, it is a good idea to configure the HART Point into the point-topoint mode. The HART modules do not use, and are not associated with, any Analog Inputs, whether built-in or modular. The HART module can power the HART device(s), and communicate digital
HART Protocol only using the I/O termination block associated with the HART Module.
HART Point — Enable or disable the corresponding built-in analog input (AI) point for HART operation. If turned OFF, no ROC memory is allocated for HART on the AI point. Turning this parameter ON causes the ROC to check memory allocation and build new HART device data templates, if required.
Scanning — Enable or disable the polling of the HART devices. Scanning should be disabled (OFF) if a device is being replaced or if continuous polling is done from another source such as a hand-held configuration device. Scanning must be enabled (ON) to use the HART device.
Enabling or disabling Scanning has no effect on the ROC memory allocation of HART device data.
Device Type — This feature is currently inactive. All HART Points are inputs.
HART Mode — This field determines the operating mode of the HART Point. The operating mode may be Single (point-to-point) or Multi-Drop, with the Device Tag value denoting the number of devices on the drop. Changing this parameter causes the ROC to Check Memory Allocation and build new HART device data templates if required.
Device Tags 1 through X — The Device Tag identifies each HART device in the multi-drop mode. A unique tag must be placed in a device prior to its installation on the multi-drop point. You can modify the Device Tag by using the Config Hart device display. Refer to Section 5, Device
Tag. Be sure to enter the most current Device Tag in these fields. Press (F2)Prev and (F3)Next to view each of the points.
NOTE
It is not recommended that a HART device be used for inputs to PID controls or
AGA calculations unless the input is used in a slow-acting process.

Low Alarm — If the Primary Value is less than this value, in engineering units, and Alarming is
Enabled, a Low Alarm generates and an entry is made to the Alarm Log. This alarm clears if the Primary Value minus the Alarm Deadband value is greater than the Low Alarm. Out-of range alarms are typically set around 3.95 mA.
High Alarm — If the Primary Value is less than this value, in engineering units, and Alarming is
Enabled, a High Alarm generates, and an entry is made to the Alarm Log. This alarm clears if the Primary Value plus the Alarm Deadband value is less than the High Alarm. Threshold alarms are typically set around 20.3 mA.
LoLo Alarm — If the Primary Value is less than this value, in engineering units, and Alarming is
Enabled, a Low-Low Alarm generates, and an entry is made to the Alarm Log. The value is set lower than the Low Alarm. This alarm clears if the Primary Value minus the Alarm Deadband value is greater than the LoLo Alarm. Threshold alarms are typically set around 3.78 mA.
HiHi Alarm — If the Primary Value is less than this value, in engineering units, and Alarming is
Enabled, a High-High Alarm generates, and an entry is made to the Alarm Log. The value is set higher than the High Alarm. This alarm clears if the Primary Value plus the Alarm Deadband value is less than the HiHi Alarm. Out-of -range alarms are typically set around 20.9 mA.
Rate Alarm — This value denotes the amount of change required from the previous update of the
Primary Value before a Rate Alarm generates and an entry is made to the Alarm Log. The value, in engineering units, that represents the maximum amount of change allowed between updates. If the change is equal to, or greater than this value, a Rate Alarm is generated.
Alarm Deadband — This is the inactive zone around the alarm values. When the Primary Value leaves this zone, the alarm clears. The value, in engineering units, is an inactive zone above the
Low Alarm limits and below the High Alarm limits. The purpose of the Alarm Deadband is to prevent the alarm from being set and cleared continuously when the input value is oscillating around the alarm limits. This also prevents the Alarm Log from being over-filled with data.
Active Alarms — This field indicates any alarms that are active for this point. When Alarming is
Enabled, the limit alarms (such as Low Alarm and Rate Alarm) that are active appear. Even if
Alarming is Disabled, the Point Fail alarm and Manual (Scanning Disabled) indicators can still appear. If Alarming is Enabled, an alarm is generated when Scanning is Disabled.
If Alarming is Enabled and there is no response from the HART device for ten consecutive polls, a Point Fail alarm code is set in the Active Alarms field of the Alarms/Device Status dialog. In addition, if you are using the HART Interface Card program, the value of the Primary
Value parameter will be set to - 9999.0. All alarms will still be recorded in the Alarm Log.

Sensor Limit or Lower Sensor Limit. The analog signal and digital values read by the HART
Commands are unreliable.
♦
Configuration Change – The Host or local operator interface (LOI) has changed the Slave’s configuration. Primary Host should recognize this bit and re-read configuration information and then transmit Command 38 to clear the configuration bit.
♦
Non-PV Out of Limits – Variable other than the Process Variable or Primary Value out of limits. The analog signal and digital values read by the HART Commands are unreliable.
There is no way to identify the specific variable.
♦
Cold Start – HART device has been powered up.
♦
PV Output Saturated – Measurement is outside the linear analog output range (Lower
Output Limit - 0.6% through Upper Output Limit +5%). A linear overrange band, typically –
0.63% (3.9mA) to +105% (20.8mA) is often allowed before this error occurs.
♦

Alarm Enable — Setting this field to “1” enables alarming on the Primary Variable and the logging of alarms to the ROC Alarm Log. Setting the field to “0” disables the alarming function.
If Alarm Enable is set to “1” and there is no response from the HART device for ten consecutive polls, the Point Fail bit in the Alarm Code parameter will be set to “1.” In addition, if you are using the HART Interface Card program, the value of the Primary
Variable parameter will be set to -9999.0. All alarms will still be recorded in the Alarm
Log.
Low Alarm EU — If the Primary Variable is less than this value and alarming is enabled, a
Low Alarm generates, and an entry is made to the Alarm Log. This alarm clears if the
Primary Variable minus the Alarm Deadband value is greater than the Low Alarm EU.
High Alarm EU — If the Primary Variable is greater than this value and alarming is enabled, a
High Alarm generates, and an entry is made to the Alarm Log. This alarm clears if the
Primary Variable plus the Alarm Deadband value is less than the High Alarm EU.
LoLo Alarm EU — If the Primary Variable is less than this value and alarming is enabled, a low-low alarm generates, and an entry is made to the Alarm Log. This alarm clears if the Primary Variable minus the Alarm Deadband value is greater than the LoLo Alarm
EU.

HiHi Alarm EU — If the Primary Variable is greater than this value and alarming is enabled, a
High-High Alarm generates, and an entry is made to the Alarm Log. This alarm clears if the Primary Variable plus the Alarm Deadband value is less than the HiHi Alarm EU.
Rate Alarm — This value denotes the amount of change required from the previous update of
Primary Variable before a Rate Alarm is generated and an entry is made to the Alarm
Log.
Alarm Deadband — The value, in engineering units, is an inactive zone above the Low Alarm limits and below the High Alarm limits. The purpose of the Alarm Deadband is to prevent the alarm from being set and cleared continuously when the input value is oscillating around the alarm limit. This also prevents the Alarm Log from being overfilled with data. When the Primary Variable leaves this zone, the alarm clears.

6.1 HART COMMANDS
The ROC or FloBoss is considered to be a HART Host (primary master) interface with a Class 1
Conformance classification. Most Universal and some Common Practice Commands are supported as
listed in Table 6-1. The supported Universal Commands are numbered 0 through 18 and the Common
Practice Commands supported are numbered 33 through 38. The supported Commands conform to
Revision 5.1 of the Universal Command Specification and Revision 7.0 of the Common-Practice
Command Specification (as found in the HART - Smart Communications Protocol document).
Because the ROC operates as a HART Host, it can request and write parameters to a HART device.
Various modes of operation can be further configured with the ROC.
The Primary Variable or Process Value can be represented in engineering units (EUs) with Command 1 or Command 3 and the PV can be represented as a percent of range using Command 2. Command 3 can also represent the actual analog output current in milliamps.

6.1.1 HART Message Frames
Refer to Figure 6-1 concerning the structure of HART message frames.
Preamble Start Address Command Byte Count Status
Figure 6-1. HART Message Frame
Data Checksum
Preamble — Between 5 and 20 bytes of hexadecimal FF characters that are all 1’s. HART devices use the Preamble to synchronize to the character stream.
Start — One byte in length and may include several values indicating the type of message such as:
Host to Slave, Slave to Host, and address format (long or short frame).
6-2 Rev 3/99
HART Program User Manual
Address — Includes both the Host address and the Slave address. The Host address is a single bit with the most significant bit (MSB) of the address field either representing the primary Host as 1 or representing the secondary Host as 0. In a short frame, the Slave address is four bits representing the polling address of 0 through 15. In a long frame, the Slave address is 38 bits containing the Device Tag and one bit indicating if the Slave is in Broadcast mode. The ROC and FloBoss units do not support Broadcast (burst) mode. Long frame formats do not use the polling address. The remaining 38 bits of the five-byte address field contain the Slave’s unique identifier as an address.
Command — One byte (0 to hexadecimal FD or decimal 253) contains the HART Command message.
Refer to Section 6, HART Commands. The Command code is echoed back by the Slave in the reply message.
Byte Count — The number of bytes to follow in the Status and Data bytes fields. The Slave uses the
Byte Count to know when the message is complete. Byte Count functions as the end of message indicator. The Data field is limited to 25 bytes maximum so the Byte Count range is 0 to 27.
Status — Two-byte response code. Present in the response message sent from the Slave. The two bytes include information about outgoing communication errors in the return message
(Command Response), the Status of the received Command (device is busy or does not recognize the Command), and the operational Device Status of the HART Slave.
Command Response codes are integers from 0 through 127 and indicate errors or warnings, which may have single or multiple meanings. Refer to Table 5-1. The Command Response code may be applicable to any transaction or have multiple meanings specific to a Universal or
Common Practice Command. A Command Response code includes both fault conditions and abnormal operational modes or conditions, which do not indicate a faulty device.
Communication errors are typically errors in parity, overrun, and framing errors. An overflow of the receive buffer or discrepancies between the message content and the received checksum may occur.
Data — Depending on the HART Command, the Data field may or may not be present. A maximum length of 25 bytes is recommended. The number of bytes of data and the formatted data used
for each item are designated by each Command. Refer to Table 6-1, HART Commands. Data
may be in the form of:
♦
Integers – 8, 16, 24, or 32 bits, unsigned.
♦
Floating point numbers – IEEE 754 single-precision floating point format.
♦
ASCII character strings – usually packed four characters into each three bytes.
♦
Enumerated items from a standard list – code as 8-bit integers.
Rev 3/99
If a Command is unsuccessful, the return Command Response message will not contain Data. A successful Command always includes the same set of variables as were contained in the
Command message; however, the values in the return response message are those actually used and acquired from the Slave device’s memory.
6-3
HART Program User Manual
Checksum — One byte containing the longitudinal parity (exclusive-or) of all other bytes (Start through Data) with Parity bit attached to each byte. The Checksum byte is used to detect communication errors and message corruption.
The least significant byte (LSB) is always sent first.

6.2 FULL UPDATE
A full update requests data from a HART device using most of the read Commands supported (such as
HART Commands 0, 11, 12, 13, 14, and 15). The full update is initiated automatically on power-up and after a major change in the configuration of a HART Point has been made. A major change is defined as a reconfiguration from point-to-point mode to multi-drop mode or vice-versa, or the addition or deletion of a device in the multi-drop mode.
A full update can also be performed on-demand either by using GV101, ROCLINK, or by using a remote host. Refer to either of the procedures below:

6.3 POLLING METHODS
A HART data poll by the ROC is defined as the data that is continuously requested from the HART device. The ROC allows four different polling sequences or methods. The amount of time spent gathering data from a device depends upon the polling method used. Each polling method always updates the Response Code and Device Status parameters. The following table shows these polling methods.

6.4 WRITING PARAMETERS
To write or change a parameter in a HART device, the parameter must first be changed and saved into
ROC memory (Write to EEPROM or Write to Internal Config Memory). After the parameter is changed in ROC memory, a Command (Write Changes) must be issued to write the data to the HART device. The ROC issues a Command to the HART device to change the parameter, and then automatically follows with a full update request to update any data in ROC memory that may have been affected by the parameter change. Refer to:
♦

SECTION 7 — USING HART PARAMETERS
7.1 USING HART PARAMETERS WITH THE ROC
The HART parameters are referenced by Type, Logical Number, and Parameter (TLP) in the same manner as the rest of the ROC parameters. This allows access to all the ROC functions when using the
GV101 Configuration Software or ROCLINK.
For example, a HART Primary Variable or Primary Value can be assigned as an input (in a slow-acting process) to an AGA3 Flow Calculation, a process variable for a PID Loop, a Tank Level in Tank
Volume Calculations, as a variable for 35 days of hourly history archival, as a variable to display on the
Local Display, and as an item on the user-configured ROC Displays.
The HART parameters are also included in the ROC Event Log whenever a HART parameter is changed, showing the description, time of change, old value, new value, and who initiated the change.
7.2 USING HART WITH ROC PROTOCOL
The HART parameters can be accessed using Opcodes 166 and 167 (Block Read and Block Write),
Opcodes 180 and 181 (Parameter Read and Parameter Write), and also through the Configured Opcodes by configuring a HART parameter in the Opcode parameter tables. More information can be obtained from the ROC Protocol User Manual (Form A4199).
7.3 USING HART WITH MODBUS PROTOCOL
Since all of the supported HART parameters also reside in the ROC memory, any parameter can be mapped to a Modbus register using the ROC Modbus Protocol. Any parameter can be read using mapping and can also be written to if the parameter has Write enabled. Accessing different data types
(ASCII, Floating, Byte, Integer, Long) depends upon the Host system.
