8315 L&J Tankway Interface Module 20 TankGate Interface Installation and Operations Manual
8300 4 8315 L&J Tankway Software Description 8315 L&J Tankway Software Description The TankGate software platform is based on a real-time, multi-tasking operating system. The software consists of I/O scanning functions for data acquisition, a database/database manager and communication functions for data transfer. Figure 4-1: Software Block Diagram 4.1 Software Features 4.1.
8315 L&J Tankway Software Description 4.1.4 TankGate Interface Communications There are two communications tasks - one for each of the communication channels. COM ports 0 and1 are used to interface to external devices or host systems. Refer to the Hardware Chapter for the location of these ports. 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: 4.1.
8300 8315 L&J Tankway Software Description 4.2 TankGate Software Blocks The user can configure pre-defined subprograms known as Software Blocks. These software blocks program the TankGate 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.
8315 L&J Tankway Software Description 4.3 TankGate Interface Database Organization Points are the individual instances of software blocks. Examples include Whessoe Varec 1900 (WV1900) and SCALER points. In both cases the user configures the Config parameters and is provided real time data through the Dynamic parameters. 4.3.1 Point Format Data parameters in the TankGate are addressed using a “Type.Number.Parameter” format. For example, “WV1900.02.
8300 8315 L&J Tankway Software Description Note! 4.3.2.2 ViewRTU inserts default values for the Config parameters when the point is first defined. It is usually only necessary to fill in a few configuration parameters, such as channel numbers, to configure references and to configure links to other points.
8315 L&J Tankway Software Description TankGate Interface 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 TankGate re-calculates the checksum. The PntCheckSum is used at initialization to validate each point in the database.
8300 8315 L&J Tankway Software Description 4.4 Gathering Point Data For Host to TankGate communications, there are two primary methods for gathering point data. These methods are listed below: 4.4.1 Standard Request-Response Format The Host issues scan requests, and the TankGate 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.
8315 L&J Tankway Software Description 28 TankGate Interface Parameter Description Deadband LevelDeadband TempDeadband 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.
8300 8315 L&J Tankway Software Description 4.5 Modbus Communications The TankGate is capable of communicating with Modbus compatible devices. It is possible to communicate with both Modbus Masters and Slave devices. The TankGate 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.
8315 L&J Tankway Software Description TankGate Interface TankGate responds to the following Function Codes: Function Code Description Comments 3 Read Output Register FC 3 and FC 4 are treated the same. Use either FC 3 or FC 4 to read data from the TankGate 4 Read Input Register 5 Force Single Output Status 6 Preset Single Register 15 Force Multiple Outputs 16 Preset Multiple Registers FC 4 and FC 6 are treated the same.

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.

8300 7 Troubleshooting Troubleshooting 7.1 Overview This chapter describes the procedures used to isolate hardware faults. Three pushbuttons and eight status Led provide verification of TankGate proper operation. If the TankGate is not functioning normally, the user is able to troubleshoot the device by performing one or more procedures using the three push-buttons. These push-buttons and indicators are also described in the Motherboard & I/O Expansion Module Configuration chapter. 7.
Troubleshooting TankGate Interface by observing the RUN Indicator duty cycle. Under normal conditions, this indicator flashes once every second. 7.2.1.2 Communications indicator The Communications indicator provides communication line status. When it is toggling, the system is exchanging data. As the system receives a valid message from the Host, this indicator toggles. If the indicator is idle, the system is off-line. 7.2.1.
8300 Troubleshooting 7.2.4 • Reset All Timers • Disable Outputs • Enable Communications • Present Sign-on Message to Diagnostic Terminal Performing a Hard Reset A ‘Hard Reset’ clears the TankGate’s database. The following procedure describes the steps necessary to perform a Hard Reset: 1. Set the ID DIP switch to 15 (all switches Closed/On). This action initiates the Hard Reset Procedure. Figure 7-1: Set the ID DIP switch to 15 ID = 15 2.
Troubleshooting TankGate Interface 4. Set the ID DIP Switch to the desired address (1-14). At this point, there is no further action required by the user. Figure 7-3: Set the ID DIP switch to the desired addresses ID = 1 5. The LEDs will light (and remain steady) to indicate the address. For example, if the ID DIP Switch is set to 1, LEDS D1 will on. If the ID DIP Switch is set to 3, LEDS D1 and D2 will be on. Figure 7-4: Address indication from the LEDs D1 ON D2 D3 D4 ID = 1 6.
8300 Troubleshooting 7.3 Maintenance Field maintenance of the TankGate 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 TankGate: 7.3.0.1 Replacing a defective component or module • Turn off main power. • Open the enclosure door. Remove the case cover of the TankGate.
