Chapter 1 – Introduction
Caution When implementing control using thi s product, observe best industry
practices as suggested by applicabl e 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 Interface Program for the
ROC800-Series (ROC800) Remote Operations Controllers.
1.1 Scope and Organization
This document serves as the user manual for the Gas Chromatograph
Interface program, which is intended for use in a ROC800.
This manual describes how to download, install, and configure the Gas
Chromatograph 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 loaded on a personal computer (PC) running
Windows® 2000 (with Service Pack 2), Windows XP (with Service
Pack 3), Windows Vista (32-bit), or Windows 7 (32-bit 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, 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 ROC800 and its
configuration. For more information, refer to the following manuals:

1.2 Product Overview
The GC Interface program enables the ROC800 to communicate
directly with one gas chromatograph (GC) on an EIA-232 (RS-232) or
up to two GCs on an EIA-485 (RS-485) communications port.
Supported gas chromatographs include the Rosemount Analytical
(including Danalyzer) Model 500 series, Model 700 series, Model
(part D301217X012)
Series) (part D301250X012)
Revised October-2016 Introduction 1
Gas Chromatograph Interface Program User Manual (for ROC800-Series)
1000/1000A series, 370XA, 700XA series, and 1500XA series. This
includes the associated 2251, 2350, 2350A, and 2360 controllers.
The program communicates directly with the GC using Modbus
protocol (in which the ROC800 has Master status). The ROC800 polls
data from the GC, validates that data, and updates the appropriate
station 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. The total number of streams the program
can process may be limited by the number of stream licenses available
in the ROC800. This value is listed in the App Code field on the License
Key Administrator screen (Utilities > License Key Administrator) in
ROCLINK 800. Refer to Section 2.1.1 for further information on the
ROC800 license keys.
The program assigns a type of gas or liquid for each GC supported. This
allows the program to write GC data to either gas stations (for
measurement of natural gas or related hydrocarbon gases) or liquid
stations when used with a ROC800L (for measurement of light
hydrocarbon liquids).
In order to update station data in the ROC800, you must assign the
streams to gas or liquid station(s) in the database of the ROC800. In the
case of gas, this allows the ROC800 to log the gas component data,
heating value, and specific gravity and use these values in volume,
mass, and energy calculations. In the case of liquid, this allows the
ROC800L to use the fluid component data to calculate the mass, volume
and density of the measured product.
1.2.1 Communications Wiring
The GC must be connected to the communications port on the ROC800
using 12 AWG (or smaller) wire. Figure 1 shows the wiring for an EIA232 (RS-232) to a 2350A GC.

1.2.2 Autoconfigure
The GC Program provides an autoconfigure option on the GC Interface
screen (see Figure 17). 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 # frame 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. Then, when you select
Autoconfigure, the program sets the selected communication port
parameters to the following values:

The program automatically configures the Modbus Master Table using
values in the Comm Port # and Modbus Address fields on the GC
Interface screen to poll for the following registers in the GC:
Note: The following values are in accordance with the SIM 2251
Modbus register map.
The Autoconfigure option configures 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:

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 .
The Autoconfigure option will setup Modbus polling according to the
SIM 2251 Modbus register map. Manual adjustments to this Modbus
configuration may be necessary, depending on the gas chromatograph
device make and model.
Finally, when the auto-configure process completes, the program
disables the auto-configure parameter.
Note: After the autoconfigure 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 (66,0,17) and the last poll must be stored in a
register mapped to GC Stream parameter Sample Min End
(66,0,16).
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 station. Checks
include:
The Communication Status (Point 121, Parameter 6, 12, 18, etc.)
must return valid responses (value of 8) for all registers polled. The
program does not copy gas analysis data to the station if errors are
present.
If Bypass Alarm 1 (Point 65, Parameter 11) is disabled, the Alarm
Flag 1 (Point 66, Parameter 18, bits 14 & 15) from the GC is
Revised October-2016 Introduction 7
Gas Chromatograph Interface Program User Manual (for ROC800-Series)
checked for errors. The program does not copy gas analysis data to
the station if errors are present.
If Bypass Alarm 2 (Point 65, Parameter 12) is disabled, the Alarm
Flag 2 (Point 66, Parameter 19, bits 0, 1, 2 & 3) from the GC is
checked for errors. The program does not copy gas analysis data to
the station if errors are present.
The Calibration Flag (Point 66, Parameter 20) is checked to ensure it
is in the Analysis State. The program does not copy gas analysis
data to the station if the Calibration Flag is not in the Analysis State.
The Starting Sample Minute (Point 66, Parameter 17) must be
different than the previous or the program does not copy gas
analysis data to the station.
The Starting Sample Minute (Point 66, Parameter 17) and Ending
Sample Minute (Point 66, Parameter 16) in the poll must match or
the program does not copy gas analysis data to the station.
The current Stream Number (Point 66, Parameter 2) must be
assigned to a station and have a license key.
The Total Un-Normalized Mole % (Point 66, Parameter 9) must be
within plus or minus Total Mole % Deviation (Point 65, Parameter
14) of 100%. The program does not copy gas analysis data to the
station if the value is outside of this limit.
The Mole Sum (Point 66, Parameter 21) must be within plus or
minus Total Mole % Deviation (Point 65, Parameter 14) of 100%.
The program does not copy gas analysis data to the station if the
value is outside of this limit.
The Heating Value [Point 66, Parameter 4 (dry) or 5 (wet)] must be
between the Heating Value Low Limit (Point 65, Parameter 9) and
Heating Value High Limit (Point 65, Parameter 10) set on the GC
Config screen. The program does not copy gas analysis data to the
station if the value is outside of these limits.
Note: Unless you enable the HV Limits on the GC Stream Data
screen, the program uses the Heating Value limits on the GC
Config screen as the global limits for all streams in the GC.
If you enable HV Limits (Point 66, Parameter 90) on the GC Stream
Data screen, the program checks that the Stream Heating Value is
between the BTU Low Limit (Point 66, Parameter 91) and BTU
High Limit (Point 66 Parameter 92) values. If this value is outside of
these limits, the program does not copy gas analysis data to the
station.

The Specific Gravity (Point 66, Parameter 6) must be between 0.07
1.3 Program Features
Note: The HV Limits on the GC Stream Data screen are set on a
per-stream basis. If you enable HV Limits, the values entered
in the BTU Low Limit and BTU High Limit fields overrides
the Heating Value limits set on the GC Config screen for the
selected stream only.
and 1.52. The program does not copy gas analysis data to the station
if this value is outside of the limits.
Note: The program copies each GC stream component to its
corresponding component in the station, with the exception
of neo-pentane. Neo-pentane is added to the iso-pentane
component and then copied to the station. The heating value
and specific gravity are also copied to the appropriate
station.

1.3.1 License Key
License keys, when matched with valid license codes, grant access to
applications such as the GC Interface program.
The term “license key” refers to the physical piece of hardware that can
contain up to seven different licenses (refer to Figure 6). Each ROC800
can have none, one, or two license keys installed. If you remove a
license key after enabling an application, the firmware disables the task
from running. This prevents unauthorized execution of protected
applications in a ROC800.
