  • Page 14: Getting Started

    <3. Getting started> Getting started FOUNDATION Fieldbus is fully dependent upon digital communication protocol and differs in operation from conventional 4 to 20 mA transmission communication protocol. It is recommended that novice users use field devices in accordance with the procedures described in this section. The procedures assume that field devices will be set up on a bench or an instrument shop. Connection of Devices The following instruments are required for use with FOUNDATION Fieldbus devices: • Power supply FOUNDATION Fieldbus requires a dedicated power supply.

  • Page 15: 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.

    <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. A new designated value should be displayed.

  • Page 18: 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 19: 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. The maximum current consumed (power supply voltage 9 to 32 V) for FLXA21 is 26.0 mA.

  • Page 20: 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 23 <4. Configuration> Typical example is a human-machine interface (Client) to read data of a Function Block (Server). The Client sends a Read request to the Server and then the Server sends back the data to the Client. This communication is unscheduled and is handled during the unscheduled interval in the macrocycle. A Client may want to issue many requests at a time. A Client-Server VCR has a queue to store those requests and sends the requests one by one when the node has the token. Source(-Sink) Model A Source-Sink VCR is designed to broadcast messages. It is one-to-many one-way communication without any schedule.
  • Page 24 <4. Configuration> Table 4.4 VCR Static Entry Sub- Parameter Description index FasArTypeAndRole Indicates the type and role of communication (VCR). The following 3 types are used for FLXA21. 0x32: Server (Responds to requests from host.) 0x44: Source (Transmits alarm or trend.) 0x66: Publisher (Sends AI block output to other blocks.)

    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 97 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...

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. Select the device(s) to which you Select device(s) want to download software.
  • Page 108 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. The device type is “0402” for FLXA21-PH, and is “0403” for FLXA21-SC. The software name is “ORIGINAL” or “UPDATE.” The former indicates an original file and the latter an update file. Whenever performing a download to update the device revision, obtain the original file. In general, an addition to the parameters or blocks requires a device revision update. Steps after Activating a Field Device When the communication with a field device has recovered after activating the device, check using the download tool that the software revision of the field device has been updated accordingly. The value of SOFT_REV of the resource block indicates the software revision.
