Introduction 1
Section 1: Introduction
This manual provides information required to understand the specifications for the ROC protocol.
The intended use is for developing communication drivers to interface with a FB Series flow
computer.
The ROC database is broken into individual parameters. Each database parameter is uniquely
associated by parameter number and point type. See Chapter 3, Parameter Lists for Point Types, for
detailed information.
Note:
For simplicity, this manual uses the term “FB Series” when referring to the Emerson FB1100,
FB1200, FB2100 and FB2200 flow computers. Unless otherwise noted, the descriptions and
procedures apply to all FB Series devices using the ROC protocol.

A message generally contains the following fields, in order from left to right:
Field
Description
Destination
Specifies the address for the destination device. Destination has two
components:
Unit
One-byte unit code for the station address. The unit
code for a ROC address is user-configurable. For a host,
this must be a unique number. 0 represents “broadcast
within group” and 240 is the “direct connect address.”
Group
Indicates the group code for the station address. This is
user-configurable.
Source
Specifies the address for the source device. Source has two
components:
Unit
One-byte unit code for the station address. The unit
code for a ROC address is user-configurable. For a
host, this must be a unique number. 0 represents
“broadcast within group” and 240 is the “direct
connect address.”
Group
Indicates the group code for the station address. This
is user-configurable.
Opcode
Defines the operation code (opcode) action to perform. See Section 2
for description of supported opcodes.
# of bytes
Indicates the number of bytes in the data byte field, consisting of the
path, desired opcode, number of data bytes for the desired message,
and the desired message itself.
Data Bytes
Contains messages of varying lengths, consisting of the path, desired
opcode, number of data bytes for the desired message, and the
message itself.

Introduction 3
CRC
Confirms validity of message transmission.
lsb
Least significant byte.
msb
Most significant byte.
Messages are of flexible length. The first six data bytes are used for the header information
including: destination, source, opcode, and data length (number of bytes). The length of a
message equals the number of data bytes transmitted plus eight overhead bytes (header
information and CRC).
The minimum message length is eight bytes if the number of data bytes is zero (no data bytes
transmitted). The maximum message length is 248 bytes (240 bytes of data). a byte.
Tables 1-4 and 1-5 provide examples of the messages exchanged if the host requests the current
time and date from ROC 13 of Group 5.

1.3 Calculating Data Offsets
A data byte offset is the offset (zero-based) from the beginning of a transmit or receive buffer for
the data items that comprise the opcode data. The offset of the first data item is always 6 to allow
for the header information (bytes 0-5).
Certain data offset values are determined based on the ROC configuration. The data byte offset for
each item may be calculated. To calculate the next data offset value, add the previous offset value
to the length of the previous data item:
Offset = Previous Offset + Length of Previous Data Item

4 Introduction
1.4 Limitations
The following limitations currently exist when FB Series devices use ROC protocol:
▪
Changes to the meter or history configuration in your FB Series device require you to issue an
Opcode 6 to update configuration information before using other Opcodes to read/write data
over ROC protocol. Additionally, Opcode 120 must be issued before making any call to retrieve
history data.
▪
New functionality such as Action or Math Blocks parameters cannot be accessed.
▪
Events for BIN (binary) data types show only the new and old value of the changed bit;
unchanged bits are not logged as events.
▪
Events logged for the user mode property associated with a meter other than the first or
integral sensor instance (for example, DP_1-2, Press_1-2, RTD_1-2) will all return the same
MVS TLP (40,0,3). This may make it difficult for users to determine what specific instance was
changed.
▪
To generate valid EFM data:
o
User Data points cannot be assigned as flow measurement inputs
o
Identical objects cannot be assigned to two different meters
▪
In cases where value precision is greater in the FB Series device than what was supported by
the FloBoss107, the extra digits will be truncated without rounding. For example, the “no flow
time limit in seconds” for Linear Meters on FB Series devices accepts a floating point number
with up to three decimal places (e.g., 5.678) whereas the FloBoss107 supports an integer
number. In this case, retrieving the value from the FB Series device over ROC protocol will yield
an integer with trailing decimal numbers removed (e.g., 5). See the DNP3 protocol manual for
a complete listing of parameter data types used by FB Series devices.
▪
Meter history collection is limited to Station 1, which resides in group 4. You cannot access the
Station 2 history group. Additionally, devices supporting two meter runs must have the second
meter history configured in group 4 (station 1).
▪
Station parameter assignments are primarily configured during a device’s initial setup. As
previously noted, the FloBoss107’s ROC protocol does not have the concept of different
stations. As a result, both meters must be assigned to Station1/history group 4. For a similar
reason, station parameter changes returned via Opcode 122 appear as if they are affecting
only meter 1. However, the FlowCal Enterprise software recognizes (via the file’s configuration
section) that the station parameter change has occurred in meter 2, but since it does not have
an associated event, the software highlights the exception. Because there is no associated
event to tag precisely when the value changed, it is advisable to make station changes as soon
as possible after the SCADA poll (that is, for a 1:00 PM poll, make changes at 1:01PM). To avoid
this issue with manually entered gas composition changes, assign each meter to a separate
Components object.

Opcodes 5
Section 2: Opcodes
This chapter details each ROC protocol opcode.
2.1 Opcode Overview
Table 2-1 briefly describes each opcode. The tables in this section provide detailed descriptions of
the various opcodes used. For each opcode, a brief description of the data bytes is provided. In
some cases, the number of data bytes returned for an opcode varies.
Certain opcodes only send data and do not receive data back from the FB Series. For example,
Opcode 8 requests the FB Series to set the time and date. The host transmits six to nine data bytes
defining the new time and date. The FB Series resets the time and date and sends back an
acknowledgment in which the opcode is repeated, but no data bytes are transmitted back. All
acknowledgments are 8-byte messages that repeat the opcode received, but do not transmit any
data bytes.
Opcode 255 is an error message indicator. This is also an 8-byte message with no data bytes
included. The opcode is set to 255 to indicate the message received by the FB Series had valid
Cyclical Redundancy Check (CRC), but contained invalid parameters. For example, if a request was
made for information on Analog Input #11, but the FB Series was configured for only eight analog
inputs (0 to 7), the FB Series would respond back with the 8-byte message with the opcode equal
to 255 (error).
The number of analog inputs varies from device to device. This variability is indicated by listing the
first analog input and indicating the remaining analog inputs by a period (“.”). In the following
tables, a period in either the Data byte(s) column or the Description of Data column indicates a
repetition of the proceeding item for the necessary number of instances.

index (239), the system will wrap back around to the first index (0) and use those older items to fill
the response buffer.
Requests which try to reference values outside the valid alarm index range (>239) will result in an
error.

2.9 Opcode 122
Opcode 122 requests up to 10 events from the Event Log in the FB Series. The Event Log consists of
a fixed number of events. The maximum number of events in the Event Log is returned in Opcode
120. Each event consists of 22 bytes, organized according to the one of the five formats described
in Tables 2-10 through 2-15. Table 2-16 shows the format used by each point type.
Note:
An Opcode 120 request can be used to retrieve the current event index pointer.
For calls which start inside the valid event index range (0-239) but request data beyond the last
index (239), the system will wrap back around to the first index (0) and use those older items to fill
the response buffer.
Requests which try to reference values outside the valid event index range (>239) will result in an
error.

Notes:
•
Old values and New values are formatted in the native data type of the parameter changed
with the Least Significant Byte (LSB) first. If the length of the parameter is less than 4 bytes,
the Old and New values start at bytes 12 and 16, respectively, with unused bytes at the end
of both the Old and New value 4-byte reserved area. For example, if the data type of the
parameter changed was a TLP type (3 bytes), the Old value would be entered in bytes 1214 and the New value would be entered in bytes 16-18, with bytes 15 and 19 unused. Refer
to Section 3.2, ROC Point Type Parameter Definitions, concerning data types.
•
If the length of the parameter is 10 bytes, the New value is entered in both the Old, New,
and Tag bytes (12 through 21) and the Old value is not retained. If the length of the
parameter is greater than 10 bytes, the first 10 bytes of the New value are entered in the
Old, New, and Tag bytes (12 through 21) and the Old value is not retained.

2.14 Opcode 167
Opcode 167 reads the configuration of a single point or it can be used to read a contiguous block of
parameters for a single point. Opcode 167 is more efficient than Opcode 180 when reading the
entire, or even partial, point configuration.
Use Opcode 167 to return the location of I/O installed in the FB Series device by “type” and
“position in the I/O database.” Specify 24 for the point type to indicate this I/O position array.
The “type” indicates the type of I/O module installed. The I/O module types are:
•
Undefined – 0
•
Discrete Input – 1
•
Discrete Output – 2
•
Analog Input – 3
•
Analog Output – 4
•
Pulse Input – 5
The order of the point type values in the array indicate the physical location of the point. This
location is used as the “L” value in the TLP value to access point information. For example if the first
bytes returned in the array are “03, 03, 03, 03, 03, 04, 04”, This first analog input point in the
database would be accessed with logical of 0, the fifth with logical of 4, and the first analog output
point would be accessed with logical of 5.

Opcode 255 is an error message indicator. This is an 8-byte message with no data bytes included.
The opcode is set to 255 to indicate that the message received by the FB Series device had valid
Cyclical Redundancy Check (CRC), but contained invalid parameters. For example, if a request was
made for information on Analog Input #11, but the FB Series device was configured for only eight
analog inputs (0 – 7), then the FB Series device would respond back with the 8-byte message with
the opcode equal to 255.

You reference data in the FB Series device by type, location or logical, and parameter (TLP). Type refers to the number of the point type. The location
or logical number is a value based on physical input or output. A parameter is a numeric value assigned to each piece of data contained in a given
point type. The tables in this section list the parameters numbers and descriptions for each of the point types.
Type, Location/Logical and Parameter (TLPs)
All supported parameters in the database are referenced via a specific TLP number using Point Type (T), Logical Number (L), and Parameter (P).

Parameter Lists for Point Types 27
Interpret the I/O information (for example, 3, 2, 14) in the following way:
•
The first number is point type. In this case 3 indicates Analog Input point type.
•
The second number is the logical/physical instance of the point type. In this case 2 indicates the physical location of the analog point to be
accessed. For I/O points this value is physical location in the database. For non-I/O point types this value is the logical instance of the point type.
See the following section for more details on the physical/logical definition.
•
The third number is the parameter number. In this case 14 indicates the Filtered Engineering Units parameter value.
Logical/Point Number Details
Within each point type, individual points are referenced by a point number or a logical number. The point numbers the ROC protocol uses for Point
Types 1 to 5 are based on a physical input or output (I/O) as stored in the database.
•
Physical Point Numbers 0 to 69:
For Point Types 1 through 5, there are Point Numbers for the field I/O and for the diagnostic inputs as follows:
— Point Numbers 0 to 63 are assigned to field I/O (integral sensor inputs, on-board RTD, on-board I/O points, extended I/O module points,
and optional I/O module points). The user can access the physical location of all I/O points through opcode 167 re ading information for
point type 24. See the ROC opcode section for additional details.
Description of I/O point logicals:
o
AI: Logical #3 - 10 (8 possible points)
o
AO: Logical #11 - 18 (8 possible points)
o
DI: Logical #19 - 28 (10 possible points)
o
DO: Logical #29 - 38 (10 possible points)
o
PI: Logical #39 - 48 (10 possible points)
A few physical locations for analog input points are predefined:
o
Location 0: Analog input point for integral sensor differential pressure data
o
Location 1: Analog input point for integral sensor static pressure data
o
Location 2: Analog input point for on-board RTD data
o
Location 3 - 10: Optional I/O board analog inputs

— Point Numbers 64 to 69 are assigned to the diagnostic (system) I/O.
Note:
The diagnostic points are not supported in the first release of the FB Series Flow Computers.
•
Logical Point Numbers 0 to 127:
For all other Point Types, the Logical Point Number is 0 to x, where x is one less than the total number of instances that exist for that Point
Type. For example, the eight instances of User Data in the new flow computer would be logical numbers 0 through 7 of the softpoint point
type for ROC protocol. A more detailed description of logical mapping for each point type is provided in the following sections.
The FB Series flow computers support up to two meter runs. The meter runs can be a mix of DP meters and linear meters. The logical
mapping for meter run point types 7, 10, 41, 42, 45, 46, and 47 is shown below.
— Two DP meters
o
Logical 0 = DP Meter 1
o
Logical 1 = DP Meter 2
— Two linear meters
o
Logical 0 = Linear Meter 1
o
Logical 1 = Linear Meter 2
— One DP and one linear meter
o
Logical 0 = DP Meter 1
o
Logical 1 = Linear Meter 1
Note:
All parameters are 0-based for each point type.

FBx Tag Mapping
A listing of the FBx Tag is mapped to each TLP with designation: Object X or Object X-Y where the object is the name of the database object, X and Y
are the instance designators in the FBx database. The instance designators map the ROC logical in most instances as follow:
•
Object_N maps to logical N-1: The IO and meter points follow different logical mappings as discussed in sections 3.1.2.
Bit Assignments
The bits in each byte are numbered 0 to 7, right to left, with bit 7 shown the furthest to the left. 1 in any bit indicates that bit is active or enabled.
