Gas Chromatograph Software Interface User Manual (for FB107)
Revised June-2017 Introduction 1
Chapter 1 – Introduction
Caution
When implementing control using this product, observe best industry
practices as suggested by applicable and appropriate environmental,
health, and safety organizations. While this product can be used as a
safety component in a system, it is NOT intended or designed to be the
ONLY safety mechanism in that system.
This chapter describes the structure of this manual and presents an
overview of the Gas Chromatograph Software Interface for the
FloBoss™ 107.
1.1 Scope and Organization
This document serves as the user manual for the Gas Chromatograph
Software Interface, which is intended for use in a FloBoss 107 (FB107).
This manual describes how to download, install, and configure the Gas
Chromatograph Software Interface user program (referred to as the “GC
Interface program” or “the program” throughout the rest of this manual).
You access and configure this program using ROCLINK™ 800
Configuration Software (version 2.40 or greater) loaded on a personal
computer (PC) running Windows® 7 (32 or 64-bit).
The sections in this manual provide information in a sequence
appropriate for first-time users. Once you become familiar with the
procedures and the software running in FB107, the manual becomes a
reference tool.
This manual has the following major sections:
Chapter 1 – Introduction
Chapter 2 – Installation
Chapter 3 – Configuration
Chapter 4 – Reference
This manual assumes that you are familiar with the FB107 and its
configuration. For more information, refer to the following manuals:
FloBoss 107 Flow Manager Instruction Manual (part
D301232X012)
ROCLINK 800 Configuration Software User Manual (for FB107)
(part D301249X012)
1.2 Product Overview
The GC Interface program enables the FB107 to communicate directly
with up to two gas chromatographs (GCs) on the same EIA-232 (RS-
232), EIA-485 (RS-485), or Ethernet communications port. Gas
Chromatographs supported include the Daniel (Danalyzer) and
Rosemount Analytical Models 500, 570, 590, 700, 770 and
Gas Chromatograph Software Interface User Manual (for FB107)
2 Introduction Revised June-2017
1000/1000A. GC controllers supported include the Daniel and
Rosemount Analytical Models 2251, 2255, 2350, 2350A and 2360. The
program communicates directly with the GC using Modbus protocol (in
which the FB107 has Master status). The FB107 polls data from the GC,
validates that data, and updates the appropriate meter run parameters
using that data. The program can poll up to eight GC streams on one GC
or up to a total of ten streams on two GCs.
Note: Using MON 2000 software, you set the Daniel GC
communications port to the SIM 2251 protocol. For all other
parameter configurations, refer to the MON 2000
documentation.
In order to update meter run data in the FB107, you must assign the
streams to a meter run in the FB107’s database. This allows the FB107
to log the gas component data, heating value, and specific gravity and
use these values in volume, mass, and energy calculations.
Note: Two versions of the program are included. Installation and
operation are identical between the two programs, but they use
different point type locations, different display numbers, and are
loaded into different program slots on the FB107.
GCInterface_1.bin loads into user program location 1 and uses
point types 22 and 23. GCInterface_2.bin loads into user
program location 2 and uses point types 25 and 26.
The manual shows installation of GCInterface_1.bin. Load
GCInterface_1.bin unless another user program is currently
installed in user program location 1.
1.2.1 Communications Wiring
The GC must be connected to the communications port on the FB107
with wiring between 16 and 24 AWG. Figure 1 shows the wiring for an
EIA-232 (RS-232) to a Daniel 2350A GC.

1.2.2 Auto-configure
The GC Program provides an auto-configure option on the GC Interface
screen (see Figure 3-2). This option enables the program to
automatically configure the communication ports and Modbus
parameters necessary to poll the GC(s). For this option to work,
however, you must first specify a communication port in the Comm
Port # field on the GC Interface screen, specify the maximum number of
streams and Modbus address for each GC in use, and modify the
Modbus register table location, if desired.
When you select Auto-configure on the GC Interface screen, the
program sets the selected communication port parameters to the
following values:
Note: The following communication port parameters are configured if
you are using an RS-232 or RS-485 module only.
Baud Rate:
9600
Data Bits:
8
Stop Bits:

When you select Auto-configure on the GC Interface screen, the
program sets the Modbus configuration parameters for the selected
communications port to the following values:

Note: Depending on the GC device, registers 9034 and 9035 may
require a Modbus conversion code to be manually configured.
When you select Auto-configure on the GC Interface screen, the
program sets the Modbus Master Tables for each GC with a valid
address. The first GC’s master table uses the first logical point for the
communications port, and the second GC (if present) uses the second
logical point for its communications port. The actual poll sequence set
for each GC is:

Note: Depending on the GC device, registers 9034 and 9035 may
require a Modbus conversion code to be manually configured.
The Modbus Register to TLP Mapping assigns TLPs to registers. The
program maps TLPs to the register table you specify in the Modbus
Register Table Location field on the GC Interface screen. The
parameters necessary for this program automatically map to the
appropriate registers.
Finally, when the auto-configure process completes, the program
disables the auto-configure parameter.
Note: After the auto-configure process completes, you may modify the
Modbus Master Table and/or the Modbus Register Table, but
register 3045 must be the first and last register polled. The first
poll must be stored in a register mapped to GC Stream parameter
Sample Min Start (23/26,0,17) and the last poll must be stored in
a register mapped to GC Stream parameter Sample Min End
(23/26,0,16).
1.2.3 Validating GC Data
When the polls are complete, the program validates the data to ensure
the polling was successful and data is correct. This validation occurs
before the program copies the GC stream data to the meter run. Checks
include:
The Communication Status (Point 121, Parameter 6, 12, 18, etc.)
must return valid responses (value of 8) for all registers polled. If
errors are present, the meter runs are not updated.
If you disable Bypass Alarm 1 (Point 22/25, Parameter 11), the
Alarm Flag 1 (Point 23/26, Parameter 18, bits 14 & 15) from the GC
is checked for errors. If errors are present, the meter runs are not
updated.
If you disable Bypass Alarm 2 (Point 22/25, Parameter 12), the
Alarm Flag 2 (Point 23/26, Parameter 19, bits 0, 1, 2 & 3) from the
GC is checked for errors. If errors are present, the meter runs are not
updated.
Gas Chromatograph Software Interface User Manual (for FB107)
6 Introduction Revised June-2017
The program checks the Calibration Flag (Point 23/26, Parameter
20) to ensure it is in the Analysis State. If it is not in the Analysis
State, the meter runs are not be updated.
The Starting Sample Minute value (Point 23/26, Parameter 17) must
be different than the previous value, or the meter runs are not
updated.
The Starting Sample Minute value (Point 23/26, Parameter 17) and
Ending Sample Minute value (Point 23/26, Parameter 16) in the poll
must match or the meter runs are not updated.
The current Stream Number (Point 23/26, Parameter 2) must be
assigned to a meter run.
The Total Un-Normalized Mole % value (Point 23/26, Parameter 9)
must be within plus or minus the Total Mole % Deviation value
(Point 22/25, Parameter 14) of 100%. If this value is outside of this
limit, the meter runs are not updated.
The Mole Sum value (Point 23/26, Parameter 21) must be within
plus or minus the Total Mole % Deviation value (Point 22/25,
Parameter 14) of 100%. If this value is outside of this limit, the
meter runs are not updated.
If you enable HV Limits (Point 23/26, Parameter 90) on the GC
Stream Data screen, ensure that the Stream Heating Value is
between the Heating Value Low (Point 23/26, Parameter 91) and
Heating Value High (Point 23/26, Parameter 92) values.
Note: If you do not enable the HV Limits (which is a per-stream
value), the module uses the Heating Value (described below) as
the default.
The Heating Value (Point 23/26, Parameter 4 or 5, depending on
Wet vs. Dry) must be between Heating Value Low (Point 22/25,
Parameter 9) and Heating Value High (Point 22/25, Parameter 10).
If this value is outside the limits, the meter runs are not updated.
Note: The Heating Value is the default parameter the module checks
first. If you have enabled the HV Limits parameter (which is a
per-stream value), that value overrides this value.
The Specific Gravity (Point 23/26, Parameter 6) must be between
0.07 and 1.52. If this value is outside of this limit, the meter runs are
not updated.
Note: The program copies each GC stream component to its
corresponding component in the meter run, with the exception
of neo-pentane. Neo-pentane is added to the iso-pentane
component and then copied to the meter run. The heating value
and specific gravity are also copied to the appropriate meter run.
