  • Page 12: About Foundation Fieldbus

    FOUNDATION Fieldbus is a bi-directional digital communication protocol for field devices, which offers an advancement implementation technologies for process control systems and is widely employed by numerous field devices. FLXA21 FOUNDATION Fieldbus communication type employs the specification standardized by The FOUNDATION Fieldbus, and provides interoperability between Yokogawa devices and those produced by other manufacturers. FOUNDATION Fieldbus comes with software consisting of three AI function blocks, providing the means to implement flexible instrumentation system. For information on other features, engineering, design, construction work, startup and maintenance of FOUNDATION Fieldbus, refer to http://www.yokogawa.com/fbs/fbs-index.htm.

    FOUNDATION Fieldbus uses twisted pair wires. To meet the Electro Magnetic Interference standards a shielded twisted pair is obligated. Refer to Yokogawa when making arrangements to purchase the recommended equipment. Connect the devices as shown in Figure 3.1. Connect the terminators at both ends of the trunk, with a minimum length of the spur laid for connection.

  • Page 21: Host Setting

    <3. Getting started> CAUTION Connecting a FOUNDATION Fieldbus configuration tool to a loop with its existing host may cause communication data scrambles resulting in a functional disorder or a system failure. Host Setting To activate FOUNDATION Fieldbus, the following settings are required for the host. CAUTION Do not turn off the power immediately after setting. When the parameters are saved to the EEPROM, the redundant processing is executed for an improvement of reliability. If the power is turned off within 60 seconds after setting is made, the modified parameters are not saved and the settings may return to the original values.

    <3. Getting started> Reading the Parameters To read FLXA21 parameters, select the AI1 block of the FLXA21 from the host screen and read the OUT parameter. The current process value is displayed. Check that MODE_BLOCK of the function block and resource block is set to AUTO, and change the signal input and read the parameter again.

  • Page 24: Configuration

    <4. Configuration> Configuration This chapter contains information on how to adapt the function and performance of the FLXA21 to suit specific applications. Because two or more devices are connected to FOUNDATION Fieldbus, settings including the requirements of all devices need to be determined. Practically, the following steps must be taken. (1) Network design Determines the devices to be connected to FOUNDATION Fieldbus and checks the capacity of the power supply.

  • Page 25: Network Definition

    <4. Configuration> • Cable Used for connecting devices. Refer to “Fieldbus Technical Information” for details of instrumentation cabling. Provide a cable sufficiently long to connect all devices. For field branch cabling, use terminal boards or a connection box as required. First, check the capacity of the power supply. The power supply capacity must be greater than the sum of the maximum current consumed by all devices to be connected to FOUNDATION Fieldbus.

  • Page 26: Definition Of Combining Function Blocks

    <4. Configuration> To ensure stable operation of FOUNDATION Fieldbus, determine the operation parameters and set them to the LM devices. While the parameters in Table 4.2 are to be set, the worst-case values of all the devices to be connected to the same FOUNDATION Fieldbus must be used. Refer to the specification of each device for details. Table 4.2 lists FLXA21 specification values.

  • Page 45: Channel

    <5. Explanation of Basic Items> 5.1.3 CHANNEL Channel is the parameter to select the signal which is calculated in Sensor Transducer Block. The values are assigned to channels. For the FLXA21 four channels are available. For the FLXA21, you can select from the PRIMARY, SECONDARY, TERTIARY, QUATENARY values assigned to the Sensor Transducer Block.

  • Page 46: L_Type

    <5. Explanation of Basic Items> 5.1.5 L_TYPE Specifies the operation function of the AI block. If set to “Direct”, the input delivered to CHANNEL is directly reflected on OUT. If set to “Indirect”, scaling by XD_SCALE and OUT_SCALE is carried out and is reflected on OUT. If set to “Indirect SQRT”, after scaling by XD_SCALE, the square root is extracted and the value scaled by OUT_SCALE is reflected on OUT. Example: Channel range is defined as 0 to 100 °C but °F units is required for HOST display. Set the following parameters: XD_SCALE: EU@0% = 0 °C EU@100% = 100 °C Unit = °C Decimal point = 2 OUT_SCALE: EU@0% = 32 °F EU@100% = 212 °F Unit = °F Decimal point = 2 XD_SCALE OUT_SCALE 100%, 212ºF PV / OUT 100%, 100ºC CHANNEL...

    App.1-1 <Appendix 1 Link Master Functions> Appendix 1 Link Master Functions Link Active Scheduler A link active scheduler (LAS) is a deterministic, centralized bus scheduler that can control communications on an H1 fieldbus segment. There is only one LAS on an H1 fieldbus segment. FLXA21 supports the following LAS functions. • PN transmission: Identifies a fieldbus device newly connected to the same fieldbus segment. PN is short for Probe Node. • PT transmission: Passes a token governing the right to transmit, to a fieldbus device on the same segment.
  • Page 107 App.1-2 <Appendix 1 Link Master Functions> In the event that the current LAS in this segment (node address 0x14) Node address: 0x14 fails, the LM with the address of 0x15 SlotTime = 5 takes its place to become the LAS. Basic device Basic device Basic device...

    For the software download tool, use only a program developed for that purpose. For details, see the software’s User’s Manual. For information about updates of software binary files for field devices and how to obtain them, visit the following web site. http://www.yokogawa.com/fld/fld-top-en.htm CAUTION Do not hook up the software download tool to a fieldbus segment while the plant is in operation, as it may temporarily disturb the communication. Always connect the tool before starting operation.

Software Download Sequence The flowchart below outlines the software download procedure. Although the time taken for the entire procedure varies depending on the size of the field bus device’s software, it generally take about 20 minutes where there is a one-to-one connection between a fieldbus device and download tool, and longer when multiple field devices are connected to the fieldbus. Start download tool Select the software file(s) you Select file(s) want to download.
  • Page 118 App.2-3 <Appendix 2 Software Download> NOTE Be careful about the noise on the fieldbus link. If the fieldbus is noisy, the downloading may take a very long time or fail. Download Files Download files have the following filenames (with the filename extension of “.ffd”). Take care to choose the correct download file for the target field device: “594543” + device family + “_” + device type + “_” + domain name + “_” + software name + “_” + software revision + “.ffd” For example, the name of the download file for FLXA21-PH may have the following name: 5945430402_0402_FLXA21PH_ORIGINAL_R101.ffd Refer to (3) DOMAIN_HEADER in page App.2-8 about each keyword of the file name.
