1 Overview
Overview
The 8300 series Tank Gate Interface acts as a tank gauge interface for data acquisition and host gateway for tank farm, pipeline or refinery applications. Options are available for interfacing to nearly any brand of tank gauge equipment or technologies, making it possible to integrate float and tape transmitters, HTG, servo, magnetostrictive and radar gauges.
Each 8300 series Tank Gate Interface unit has a built-in motherboard and specific communications module based on the local field protocol or tank gauging instrumentation requirements. The motherboard contains a serial data link to enable communication to a host
PC, PLC, or DCS.
Note! Each intelligent module is identified by a 82xx designation that matches the product designation, for example, the 8303 TGI contains a 8203 communications module.
Each module contains its own processor for fast and reliable field data scanning. Compatibility of every module also makes configuration of the internal database simple and straightforward.

Software Features
4.1.1
Real-Time / Multitasking Executive
The operation of the Tank Gate Interface is based on a highly reliable, field-proven real-time multitasking executive. It provides task switching based on real-time events and interrupts, message passing and task priorities. Its capabilities also include timed suspension of tasks, queue handlers and interrupt processing tasks.
4.1.2
Real-Time Clock
Integral to the real-time executive is the system’s real-time clock. All timed events of the Tank
Gate Interface are coordinated by this clock. In addition to the real-time executive interaction, all field data scanning is coordinated by the real-time clock.
4.1.3
Automatic Fault Recovery
The Tank Gate Interface has a watchdog timer that is periodically strobed by the microprocessor.
Should the processor suffer a lapse due to hardware or software failure, the watchdog timer will time out and the Tank Gate Interface will then be reset and normal operation will resume.

0 and1 are used to interface to external devices or host systems. Refer to the Hardware Chapter for the location of these ports.
Note COM1 is not available on the 8315 Tank Gate Interface.
COM0 and COM1
COM 0 and 1 can be configured for communications to Host systems using a variety of protocols. For COM 0 and 1 the communication interfaces include the following:
•
RS-485 for use in multi-drop configurations or long cable runs (or both)
•
RS-232 for flexibility in configuring other types of communications links such as radio and fiber optic interfaces
•
RTS/CTS lines are available for hardware handshaking.
4.1.5
Protocols
The Tank Gate Interface is fully compatible with FuelsManager® software. It is also compatible with a variety of other Host systems including through Modbus protocol.
•

Data Scanning Task
The Data Scanning Task is dedicated to the scanning of field input data from tank gauges. The input data is stored in arrays that are subsequently accessed by the Point Executive.
4.1.7
Database Manager
The Database Manager is a collection of programs and data. The Database Manager allows the
Tank Gate Interface system executive to access data from the database in an organized and program-independent manner. It resides in non-volatile RAM.
The Database Manager also contains a Database Dictionary. This dictionary describes how the database is organized and also provides information describing how data should be presented to the operator.
After power-up or system reset, a CRC verification of each point in the database is performed.
If the CRC does not have a match for the point, then it is disabled and a flag is set indicating that the point is invalid.
Installation and Operations Manual
8314 TGI Software Description
4.1.8
System Tasks
System tasks include the Calendar Task, which manages Time and Date functions. Other system tasks include utility routines for checksum calculations, diagnostics, start-up and initialization.
4.1.9
Tank Gate Interface Software Blocks
The user can configure pre-defined subprograms known as Software Blocks. These software blocks program the Tank Gate Interface to perform various tasks, such as scaling an analog input value, or scanning level, temperature and status information from a tank gauge. Various software blocks are available depending on the communication module. Each Software Block contains all the logic, constants and data to perform a particular function. Every system function of the Tank Gate Interface is accessible via a Software Block. The user only has to add Software
Blocks using ViewRTU and then configure a few parameters in order to perform a desired function.
4.2
Database Organization
Points are the individual instances of software blocks. Examples include Whessoe Varec 1900
(MSTX) and SCALER points. In both cases the user configures the Config parameters and is provided real time data through the Dynamic parameters.
4.2.1
Point Format
Data parameters in the Tank Gate Interface are addressed using a “Type.Number.Parameter” format. For example, “MSTX.02.Level” refers to MSTX Tank Gauge #2’s IEEE floating point level.
This format and corresponding fields are described below.
The TYPE field represents the Point Type. There are many different point Types in the Tank Gate
Interface, referred to generically as Tank Gate Interface Software Blocks. Some of the point types include the COM (Communications), SYS (System), MSTX (MSTX Tank Gauge) point types. Each
Type performs a different function.
The NUMBER field represents the instance of the point type. For example, the AI point may have up to 32 instances, which are addressed using the NUMBER field. Each instance shares the same data structure definition, yet each point has unique data values. In the case of the AI software block, each point manages a single input channel.
The PARAMETER field represents the items in the data structure of the point type. Examples of parameters include Value, Status, PntRef and RawValue. This field is explained in greater detail in the following section.
4.2.2
Parameter Description
Each parameter is defined by its Parameter Class and Data Type. The following subsections describe Parameter Classes, Parameter Data Formats and Common Parameters.
Parameter Classes
Each parameter, such as Value or Channel, is classified as one of the following classes:
Parameter Class Description
Config
Dynamic
Configuration parameters such as channel numbers, tags, descriptions, ranges, operating modes, point references, constants for formulas and timing information.
Real-time data such as the value or the status. Dynamic data is calculated or measured during point execution scans, which occur every 250 msec.

Common Parameters
The following parameters are found in almost all point types. These parameters are described below:
Installation and Operations Manual
8314 TGI Software Description
PntCheckSum Parameter
The PntCheckSum is a CRC-16 checksum of the Configuration Parameters of a point. Most points have the PntCheckSum parameter; a few like the CLK (Clock) Point, DIAG (Diagnostics)
Point, and the register points (BREG, IREG, and DREG) do not. Any time a Configuration
Parameter is changed, the Tank Gate Interface re-calculates the checksum. The PntCheckSum is used at initialization to validate each point in the database.
PntStatus Parameter
The PntStatus parameter gives information about point execution. Refer to the information provided for each Software Block about the particular use of the PntStatus parameter.
Elapse Parameter
The Elapse parameter usually indicates the time of the last point execution. It is used as the basis for automatic Change of State notifications.
Value Parameter
The Value parameter indicates the real-time value of the point. In the case of DI points, the Value represents a Coded value (i.e., On, Off, Opened, Closed, etc.) AI points represent the Value in an
IEEE floating point format. In most cases, the Value parameter is one of the most important parameters for a point.
Level & Temp Parameters
The Level & Temp parameters indicate the real-time tank level and temperature of the tank gauge point. There are many Software Blocks available in the Tank Gate Interface associated with tank gauge communications, including Software Blocks for every major tank gauge manufacturer.
4.3
Gathering Point Data
For Host to Tank Gate Interface communications, there are two primary methods for gathering point data. These methods are listed below:
4.3.1
Standard Request-Response Format
The Host issues scan requests, and the Tank Gate Interface responds with the data.
The Scan method has the advantage of being deterministic, the response time to a particular request will always be the same.
This method has the limitation that if there are many points defined in the Tank Gate Interface, it often takes several requests to obtain all of the data. Most of the time data has not changed since the last request, so this results in inefficiencies in update times. This situation is often the case in systems where there are many digital points that do not change frequently.
4.3.2
Change of State Format
The Host issues scan requests based on a Change of State condition. Some systems refer to this as Event Mode. The Tank Gate Interface keeps track of the items that have changed since the last Host request. The Host can issue a single request of ‘tell me what has changed since my last request.’ The Tank Gate Interface will respond with the results, which include addressing information about the data. In a typical system, this results in a significant improvement in the throughput rate for data.
Varec, Inc.
23
Software Description Tank Gate Interface
When FuelsManager is the Host system, the Change of State method has the advantage of being very efficient. Only the data that has changed is reported. Change of State is not available when using Modbus.
4.3.3
Change of State-Related Parameters
In order to support the Change of State method, many points have additional configuration parameters included.
Parameter
Value
Report
Maxtime
Deadband
LevelDeadband
TempDeadband
Description
One of the parameters which will be returned to a Change of State request by the Host.
Most Software Blocks are designed so that the Value parameter is the main parameter of interest.
Is used for Change of State processing only
Causes automatic notification to the Host (in response to a Change of State Request) when the Value Changes State.
Valid values are High, Low or No. Report = No disables notification.
Points with Report = High have higher priority than points with Report = Low.
Is used for Change of State processing only
Specifies the maximum time (in secs) between automatic Change of State data being sent to the Host in response to a Change of State Request.
When the Maxtime period expires, the Value to is forced appear as if it has changed even if is has not, ensuring that data is sent to the host periodically.
Setting Maxtime to 0 disables this option. The maximum is 255 seconds.
Affects the Change of State processing. It allows users to filter out insignificant changes, freeing the communications link to send other data.
Note Not all Host protocols support the Change of State method. The RTU Slave protocol used with FuelsManager supports either method.
Note The Modbus protocol is Scan-based. Therefore, the Report and Maxtime parameters have no meaning.
4.3.4
Modbus Communications
Some versions of the Tank Gate Interface are capable of communicating with Modbus compatible devices with both Modbus Masters and Slave devices. The Tank Gate Interface is flexible, allowing communications with devices that strictly comply with the Modicon Modbus protocol, as well as devices with more advanced Modbus implementations such as Honeywell’s
APM-SIO.
The Modbus Slave protocol handler responds to read and write requests from a Modbus master system. A detailed description of the Modbus Slave protocol handlers follows.
Modbus Slave
The Modbus Slave protocol handler is enabled by setting the Protocol parameter of a COM point to Modbus Slave. COM 0 of the Tank Gate Interface is auto sensing. If a Modbus Master requests data from the Tank Gate Interface, the Tank Gate Interface will automatically detect that Modbus is being used and invoke the Modbus Slave protocol handler. The Modbus Slave protocol handler responds to requests from Modbus masters. A MODGW point is automatically created to provide user access to the operation of the protocol handler. The MODGW point also provides dynamic information about the communications requests from the Modbus master.
24 Installation and Operations Manual
8314 TGI Software Description
The Modbus Slave protocol handler is flexible, allowing the user to set options for handling several aspects of Modbus communications. The Modbus Slave uses the GWBLK Gateway Block as a lookup table for data addresses.
The Gateway Block allows the user to specify data address and point reference combinations.
This allows the Tank Gate Interface to be used with an existing system that is already configured.
The user defines a GWBLK point and specifies which parameter in the Tank Gate Interface will be used for a particular address. When a request from a master is received, the Modbus Slave protocol handler will first search for any GWBLK points and determine if the data address of the request is specified in one of the GWBLK points. If the data address is contained in a GWBLK point, then the corresponding point reference is used to provide the data for the reply to the master.
COM 0 will automatically sense whether the host system is ViewRTU or a Modbus Master. The communications parameters for COM 0 are 9600 baud, 8 data bits and No Parity. When switching between ViewRTU and Modbus communications, it is necessary to wait 60 seconds for the current protocol to time-out. The Tank Gate Interface will go back to the auto sensing mode and wait for a request. When a request is received, the Tank Gate Interface will determine if the request is from ViewRTU or a Modbus Master. If the Tank Gate Interface has problems switching, press the Reset button and this will force the Tank Gate Interface back into the auto sensing mode.
Note COM 1 (if available) is always a Modbus Slave. The communications parameters for
COM 1 are 9600 baud, 8 data bits and No Parity. COM1 is not available on the 8315 Tank
Gate Interface
Note The Tank Gate Interface uses the ID switch in determining to which address on the communications bus to respond.

GWBLK method
The GWBLK is the preferred means to address data in the Tank Gate Interface. The GWBLK has a great deal of flexibility. Data can be scaled, or grouped using the GWBLK. The Gateway Block
(GWBLK) allows the user to specify data address and point reference combinations. This allows the Tank Gate Interface to be used with an existing system that is already configured. The Tank
Gate Interface can be tailored to meet the needs of the Host. In some cases, the Host system may have some constraints in the use of its Modbus scanner that make it necessary to use a
GWBLK. In this mode, the user defines a GWBLK point and specifies which database parameter will correspond to a particular data address. When a request from a master is received, the
Modbus Slave protocol handler will first search for any GWBLK points and determine if the data address of the request is specified in one of the GWBLK points. If the data address is contained in a GWBLK point, then the corresponding point reference is used to provide the data for the reply to the master. If the data address is not in any GWBLK point, then data will be read using the prevailing Address Mode.
The Gateway Block (GWBLK) allows the user to specify data address and point reference combinations. The GWBLK acts as a lookup table for data items in the Tank Gate Interface. The user defines a GWBLK point and specifies which database parameter will correspond to a particular data address. When a request from a master is received, the Modbus Slave protocol handler will search for any GWBLK points and determine if the data address of the request is specified in one of the GWBLK points. If the data address is contained in a GWBLK point, then the corresponding point reference is used to provide the data for the reply to the master.
The procedure for using the GWBLK is given below:
•
Add a GWBLK point. Depending upon the addressing requirements of the host system, it may be necessary to add additional GWBLKs.
•
Configure the GWBLK by setting the Address, PntRef and Size parameters to the parameters of interest in the Tank Gate Interface. Refer to the following examples:

Application
The EMUGW point is automatically created when the TankView (TSU Slave) protocol is initiated.
In order to use the TSU Slave protocol, set the Protocol parameter of the COM point to TSU Slave.
At that time, an EMUGW and an EMU point will be created to provide a user interface for configuration and control of communications with TankView or System IV. The baud rate and data link parameters are set in the COM point as well. The default is 9600, 8 data bits, No parity.
The EMUGW point keeps track of the number of requests and number of errors associated with the EMU Slave protocol. The current tank number (ID) and the point associated with the tank number (LevelRef) are updated as requests from TankView are processed. The PntRefs correlate to the SYS ADR parameter in TankView or IDs in System IV.

Value to set all of the output registers to when there is a communications or other failure. The CommFailValue works in conjunction with the Filter values. If the PntStatus of the PntRef has bits set that match the Filter, the reference value is declared invalid and the output value will be set to the
CommFailValue. This mode is overridden by DataMode = 0x02.
Addr1 is the Data Address and PntRef1 is the corresponding database parameter that will be used for a response. The default Size is 1. See the discussion below for more detail on the Size parameter.
The Filter is used to determine if the data is valid. The PntStatus of the point specified by the PntRef is read and if there are bits set that match the Filter, the source data is considered invalid. The output registers will be set to the value determined by the CommFailValue.
Dynamic Parameters
PntStatus pntCheckSum
Function
Byte value indicating status of point Values are:
0: No error
CRC-16 Checksum of point's static Configuration Parameters
Application
The GWBLK point is a look-up table used by the Modbus Slave protocol handler. Up to sixteen address-point reference pairs may be used per GWBLK point. Multiple GWBLK points may be used if necessary. The Addr parameter specifies the data address. The corresponding PntRef parameter specifies the database parameter for the request. The Gateway Block point allows you to use the 8300 series Tank Gate Interface easily in retrofit applications. It is not necessary to re-configure an existing HMI or Host system. You can configure the 8300 series Tank Gate
Interface to match the addresses used in the Host system.
When the Modbus Slave protocol handler receives a request, it searches the GWBLK points to determine if any of the Addr parameters match the request. If a match is found, the data referenced by the PntRef parameter will be used for the response.
There are three data modes: DataMode=0, which returns the data in the default format, and
DataMode=1, which returns the data in an integer format. DataMode=1 will scale IEEE floating point data to an integer value, using the Offset, Scale, ValueMin and ValueMax parameters. If
DataMode = 4, the data will be scaled to an integer by multiplying the data value times the Scale parameter.
35
Software Description Tank Gate Interface
The DataMode can also control if the data is changed to 0xFFFF if the data is invalid. The Filter parameter is compared to the PntStatus of the PntRef parameter. If bits in the PntStatus match bits in the Filter, the data is considered invalid and the a read from a modbus host will result in the data being set to 0xFFFF.
When Block Read or Write requests are received, then the way in which the Modbus Slave protocol handler responds is determined by the Size parameter.
Size Parameter
A range of addresses can be specified by setting the Size parameter. This sets the indexing mode to Number Indexing, which means that Block Read/Write requests from the Hosts are handled by stepping through the points number by number. For example, if Addr1 is 100, and
PntRef1 is MSTX.00.RawValue, then a Block Read to address 100 with a length of 8 will return the values, MSTX.00.RawValue, MSTX.01.RawValue, ... MSTX.07.RawValue. Setting the Size to 1 does not limit the read to 1 parameter, rather it indicates that block operations will be processed by stepping through points by incrementing the number, starting with parameter specified by the PntRef.

Application
The EN811 point can operate in Direct Mode. In Direct Mode, tank gauges are connected directly to a 8214 Enraf Interface Module. The 8214 Enraf Interface Module is automatically detected at startup, and an ENSCAN point is automatically created to manage the scanning task. The Module and Chan parameters determine which 8214 Enraf Interface Module will be used, and to which channel on the 8214 Enraf Interface Module the tank gauge is connected. The ID must match the Transmission Address of the 811.
Both modes provide a software interface to the Enraf 811. Scanning begins when the Module is assigned. The ScanCmd parameter determines which data items in the 811 are read. The default values are ‘BC’, which will scan for level, temperature and the alarm status. The LevelUnits and
TempUnits must match the engineering units of the gauge. Conversion from Metric to English
(or vice-versa) can be performed be setting the LevelConvert and the TempConvert parameters in the ENSCAN point associated with the EN811 point.
Commands can be issued to the gauge by setting the Command or TestCmd parameters. The user may raise or lower the servo, read the gauge ID, or store/retrieve information from the gauge’s internal data buffer.
Weights & Measures Protection
The EN811 point can be sealed when used in a Weights & Measures application. Only certain parameters can be sealed. These parameters will be shown in blue (CONSTANT parameters) when unlocked and will be grayed out when locked. To seal the point, set the WMSeal to Enable.

5.3.2
Application
The EN873 point can operate in Direct Mode. In Direct Mode, tank gauges are connected directly to a 8214 Enraf Interface Module. The 8214 Enraf Interface Module is automatically detected at startup, and an ENSCAN point is automatically created to manage the scanning task. The Module and Chan parameters determine which 8214 Enraf Interface Module will be used, and to which channel on the 8214 Enraf Interface Module the tank gauge is connected. The ID must match the Transmission Address of the 873.
Installation and Operations Manual
8314 TGI
Both modes provide a software interface to the Enraf 873. Scanning begins when the Module is assigned. The ScanCmd parameter determines which data items in the 873 are read. The default values are ‘BC’, which will scan for level, temperature and the alarm status. The LevelUnits and
TempUnits must match the engineering units of the gauge. Conversion from Metric to English
(or vice-versa) can be performed be setting the LevelConvert and the TempConvert parameters in the ENSCAN point associated with the EN873 point.
Commands can be issued to the gauge by setting the Command or TestCmd parameters. The user may read the gauge ID or store/retrieve information from the gauge’s internal data buffer.
Additionally, Item Commands can be issued to the Enraf 873 by setting the ItemCmd parameter.
These are usually two character mnemonics, such as ‘TA’ or ‘GT’. The EN873 point provides the same access to gauge data as the 847 Portable Enraf Terminal. The response is returned in the
ReplyData field.
Weights & Measures Protection
The EN873 point can be sealed when used in a Weights & Measures application. Only certain parameters can be sealed. These parameters will be shown in blue (CONSTANT parameters) when unlocked and will be grayed out when locked. To seal the point, set the WMSeal to Enable.
Note that FuelsManager must be active in order to seal or unseal a point.

Application
Direct Mode
In Direct Mode, tank gauges are connected directly to a 8214 Enraf Interface Module. The 8214
Enraf Interface Module is automatically detected at startup, and an ENSCAN point is automatically created to manage the scanning task. The Module and Chan parameters determine which 8214 Enraf Interface Module will be used, and to which channel on the 8214 Enraf
Interface Module the tank gauge is connected. The ID must match the Transmission Address of the device being scanned.
Both modes provide a software interface to Item data in the Model 854 and the Model 873.
Scanning begins when the Module is assigned. The ItemCmd parameter determines which items are read.
Filter
In some instances, the data returned from the Model 854 or Model 873 has several subfields.
The ENITEM point allows for two subfields. The Filter allows the user to separate data into two groups (rValue1/iValue1 or rValue2/iValue2). Use a ‘1’ or a ‘2’ in the corresponding position of the ReplyData field to cause the data to be converted into groups (rValue1/iValue1 or rValue2/iValue2).
Interleave
The Interleave affects how often the ENITEM point executes. In some cases, the data being scanned is not critical and can be read less often than level or temperature data. The Interleave allows the user to schedule the ENITEM point to be read less often than the EN811, EN854 and
EN873 points. If the Interleave is 100, then all of the EN811, EN854 and EN873 points are read
100 times each before the ENITEM point is scanned. To make the ENITEM point the same priority as EN811, EN854 and EN873 points, set the Interleave to 0.

The ENSCAN point monitors the status of the 8214 Enraf Interface Module. The ENSCAN point is created automatically by the 8214 Enraf Interface Module or the 8130 RTU if the CIU Mode is used. The point number will correspond to the Module such that ENSCAN.1 is created for module
1 (the 8214 Enraf Interface Module’s unit address DIP switch = 1). Use the Upload command to retrieve the data from the ENSCAN point or any other points created automatically by the 8300
TGI.
The NumRequests parameter gives the total number of requests attempted, while the
NumTimeouts and NumComErrors are the number of time-outs and communications errors.
The Addr is the current gauge ID being scanned. The Pnt parameter is the Tag of the EN811,
EN854 or EN873 point associated with the point being scanned. The current channel and command are also available
This point can set the type of engineering units for the level and temperature data (English or
Metric). The value of Level and Temp parameters for the EN811, EN854 or EN873 point depend upon the values of the LevelConvert and TempConvert parameters. The LevelUnits and
TempUnits must match the configuration of the tank gauge transmitter. If the LevelUnits and
TempUnits are incorrect, the Level and Temp will be decoded incorrectly. By setting the
LevelConvert and TempConvert the Level and Temp can be changed from English to Metric or vice-versa. If the LevelConvert and TempConvert are not set, no conversion will be performed.

The user can also set the delay between each poll as well as how long the scanner will wait for a transmitter to respond. If a transmitter is not responding, it will not be polled as often as transmitters that are on-line. The HoldOff parameter determines how often the off-line transmitter will be polled. For example, if the HoldOff is 10, then a transmitter that is off-line will be polled only one tenth as often as a transmitter that is online.
Fast Scan
The Enraf points have a parameter called the FastScanMode. Setting the FastScanMode to Enable places the Enraf point in the Fast Scan List. Points in the Fast Scan list are polled more frequently than points that are in the Normal Scan List. Scanning of tank gauges alternates between points from the Fast Scan List and the Normal Scan List. When a Fast Scan Cycle occurs, gauges are read from the Fast Scan List. When a Normal Scan Cycle occurs, gauges are read from the Normal Scan
List. The ENSCN point provides the ability to control the operation of the Fast Scan List. The
ENSCN point has several parameters that involved:
Description
Number of points to scan during each Normal Scan Cycle
Number of points to scan during each Fast Scan Cycle
If defined, the FastScanTime is used to determine when Fast Scan Cycles are performed
Number of points in the Fast Scan List
The number of gauges scanned during a Fast Scan Cycle is determined by the FastScanMax. If the value is 0, then all Enraf points with the FastScanMode set to Enable will be scanned. The
Interleave parameter controls the number of gauges read during each Normal Scan Cycle.
Example – Default method, with 1 tank in the Fast Scan List
Interleave = 1, FastScanMax=0, FastScanTime=00:00:00, EN854.00.FastScanMode = Enable (ID

6.2
Installation Safety Guidelines
•
Never attempt to make voltage measurements within the Tank Gate Interface in the field.
•
Maintenance should be performed only by authorized personnel.
•
Always turn off the power before removing the case cover.
•
Before installing/repairing any wiring to the Tank Gate Interface, make sure that the power is turned off at the main circuit breaker or switch. The power switch should be locked in the
OFF position and labeled to prevent other personnel from turning the power on during installation.
•
Before turning on power when installation is complete, make sure the cover of the Tank
Gate Interface case is in place and tightly closed. NEVER REMOVE ANY COVERS WITHOUT
FIRST TURNING OFF THE POWER.
•
To prevent shock hazards, the housing of all units should be properly grounded in accordance with the National Electric Code. A grounding conductor should be wired to the grounding terminal provided on the Tank Gate Interface.
•
In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure. To assist in air circulation, place blower fans inside the enclosure.
•
To prevent excessive heat, several steps can be taken. For most applications, normal convection cooling will keep the device components in the enclosure within the operating range. Proper spacing of components within the enclosure is usually sufficient for heat dissipation.
•
Caution should be exercised when entering any area that is posted or otherwise assumed to contain hazardous gases. Always follow the guidelines provided by the Occupational Safety and Health Administration for your own protection.

Export All
The Export All option allows the user to export all of the database in the Tank Gate Interface.
Each point type is exported to a file in the CSV file format. For example, the Analog Input points are all exported to the file ‘AI.CSV’. This means that the user can not specify each file name as the data is exported. The user does have the ability to specify the directory to export the data to. The user must create and then select the subdirectory for the export operation. We suggest
81
Using ViewRTU Tank Gate Interface
that you organize the directories with names corresponding to the Tank Gate Interface address.
If you have two Tank Gate Interface’s, use the Windows File Manager program to create subdirectories \VIEWRTU\RTU1 and \VIEWRTU\RTU2. All of the files for Tank Gate Interface #1 should be written to \VIEWRTU\RTU1; Tank Gate Interface #2’s data would go to
\VIEWRTU\RTU2 and so on.
The exported data can be edited using a spreadsheet program such as Microsoft Excel, or a database program like Microsoft Access. Many programs can read and write data in the CSV file format. You can make backups of your RCF file by exporting the data in the CSV file format.
The exported data can be read back with the Import All option. The Spreadsheet Mode also has an option to import CSV file data.
Import All
The Import All option allows the user to import the entire Tank Gate Interface database. Each point type must have been exported previously in order to import data. This can be accomplished using the Export All option, or by point type using the Spreadsheet Mode. The data is read from files in the CSV file format. For example, all of the Analog Input points are imported from the file ‘AI.CSV’. The user must select the subdirectory to import the data from.
The CSV file data can also be imported using the Spreadsheet mode.
View I/O List
The View I/O List option allows the user to create a list of the I/O points connected to the Tank
Gate Interface. The list is limited by listing points that have the Chan or Module parameters.
These parameters are always used in cases where I/O is involved. The list is created by writing to the file ‘POINTLST.TXT’ and launching the Notepad program. The user can print this file using
Notepad, or exit and return to ViewRTU.
Set Time in RTU
The Set Time in RTU option sets the time in the CLK point to the same time as the PC running

Using ViewRTU
By using ViewRTU, the user is able to define or modify sub-programs called Software Blocks.
Software blocks are used to configure the Tank Gate Interface.
Note Refer to the Tank Gate Interface Software Blocks chapter for specific examples. The chapter provides a description of the parameters for each point as well as examples of the connections to other points.
Tank Gate Interface software blocks are functions that the user can configure to perform various tasks. Software Blocks are available to scan data from a slave device, control a pump, serve data to other Host systems or perform calculations. Each function type contains both the code and data necessary to perform the function. Software Blocks are identified by their type (example:
AI, DI, LJ2000 and PUMP). Points are individual instances of software blocks. Each point must be added and then configured. Adding a point makes the point available for configuration. All defined points appear in both the Point Icon Selection area and the Spreadsheet Summary in the main window.
Configuring the point involves entering configuration parameters. In some cases, connections to other points are required in order to perform a task. Creating connections involves setting references to allow data to be transferred between points.
7.6.1

Only valid references appear in the list boxes contained in this dialog box. The new reference can then be downloaded to the Tank Gate Interface or stored locally if the Tank Gate Interface is off-line.
7.6.4
Configuring Multiple Points
The spreadsheet mode is one of the methods used to configure points. This method is the most beneficial when editing and viewing multiple points of the same type. Spreadsheets of each defined point are found in the Spreadsheet Summary section in the main window.
There are some differences between the regular and spreadsheet methods. First, the user is not able to view the Point Connections window in Spreadsheet Mode. This mode is used mainly for viewing and entering point data. Second, the spreadsheet focuses on points of a single type; it does not offer a “big picture” view of multiple point types.
Adding Multiple Points
The user is able to add a point by using the same method used to add single points.
The user can click on the Add Point icon or push-button from the toolbar or by selecting Add from the Point menu in the Main window. Once the point is added, the user is then able to define the point. Defined points appear in the Point Icon Selection
Area and in the Spreadsheet Summary of the Main window.
Note The user can add a point by selecting Add from the Point menu in the Spreadsheet
Mode window. This menu is described later in the section.

Maintenance
Field maintenance of the Tank Gate Interface is simplified by several built-in features. The modular design of the computer control system, in conjunction with quick-disconnect connectors, allows for on-site replacement of questionable components.
The following standard procedure can be used for repairing the Tank Gate Interface:
Replacing a defective component or module
•
Turn off main power.
•
Open the enclosure door. Remove the case cover of the Tank Gate Interface.
•
Replace the defective component or module using the instruction supplied with the spare part.
