Tag Import Configuration Steps

• Export the Fixed or Custom Modbus Map report .csv
  file from the HC Designer configuration
• For Fixed Modbus map applications
• In HC Designer, go to FilegtExport, click on
  FBDs, choose All Modbus Registers, rename the
  file as desired, then store in known folder.
• For Custom map applications
• In HC Designer, go to FilegtExport, click on
  FBDs, choose All Modbus Partitions, rename the
  file as desired, then store in known folder.

Tag Import Configuration Steps Fixed Map

• Connect HC900 to the Specview application via
  Ethernet, then start Specview
• In Specviews Configurations Found dialog,
  click on Test Comms for NEW Config and enter
  new project file name
• In Specviews Ports and Protocols dialog, enter
  Begin and End IP address for HC900, then click on
  Start Scan button

7
Tag Import Configuration Steps Fixed Map

• To import the Modbus map file, click on Yes for
  the following dialog
• Browse for the AllMobusRegisters tag export
  .csv file from HC Designer, then click on Open

8
Tag Import Configuration Steps Fixed Map

• The following will now occur
• All Control loop, SP programmer, other function
  blocks, signal tags, and variables will be
  imported, categorized, and placed into the
  Variables list.
• A screen (in Configuration mode) will be
  displayed with all of the tagged Instrument Views
  related to the HC900 configuration import
  (example below). Click OK to continue. This
  display can be saved if desired and viewed
  on-line as a test.

Tag Import Configuration Steps Fixed Map

• The Variables list is populated as follows

All function blocks are listed by HC
Designer-assigned tag name for access to
associated parameters
Check Include Name to provide name text for
Variable selected
The Signal Tags and Variables lists show all
listed by number (for reference) and tag
name, data type pre-assigned as Analog or Boolean
(digital), read only or read/write
Uncheck Include Name to not include text

Tag Import Configuration Steps Custom Map

• Steps prior to tag import
• Add SP programmer blocks while in Fixed Modbus
  map mode (SP programmer blocks 1 8 supported)
• After conversion to Custom Modbus map, add
  addresses for each additional control loop (or
  other function block) to a defined Modbus map
  partition with sufficient supporting parameters
  for Specview interface
• For control loops, use Select All to add all
  control loop parameters to the map or use the
  Vista_PID.ptf template (on HC Designer CD) and
  add the LSP1 parameter (needed for writing to
  local SP)
• Add similar blocks in contiguous addresses
  within named partition
• Modify floating point data types as necessary
  (to unsigned 16) for digital status (does not
  apply to Signal Tags and Variables since digital
  types will be converted by Specview automatically
  as necessary)

11
Tag Import Configuration Steps Custom Map

• Adding control loop to Custom Modbus Map in HC
  Designer (all control loop parameters)

• Adding a control to Custom map (all paremeters)

12
Tag Import Configuration Steps Custom Map

• Adding control loop to Custom map in HC Designer
  (using Vista_PID. ptf template plus adding LSP1)

Tag Import Configuration Steps Custom Map

• Prepare Custom Modbus map (as described in
  previous slides)
• Follow import configuration steps shown for fixed
  map except
• Use the All Modbus Partitions report file for a
  new Specview configuration
• Select a specific custom map partition report
  file for import to Specview if a fixed map import
  was previously executed.

Tag Import Configuration Steps

• Adding an HC900 Controller or Updating Variables
  List
• Select the HC900 menu, then click on Import
  HCDesigner File
• Click on Add as new HC900, enter IP address,
  then browse for
• All Modbus Registers or Partitions file to add
  controller to database

HC900 Redundant Ethernet Network Support

• Overview
• Supports primary and secondary TCP/IP network IP
  addresses
• When primary communications TCP/IP network
  fails, the communications will flip to the
  secondary network, then flip back to the primary
  network only if the secondary network fails
• Typical failover time is within 1-2 scan updates
• Driver commands are available for
• Returning to the primary network once that
  network is detected to be available
• Adjusting retries and timeouts (retry default 2
  retries)

Primary network
Secondary network

• Technical Note Reference document
• A Tech Note is available in the Tech Notes
  section of Specviews FTP site.
• Go to www.specview.com, choose Tech Notes from
  the Support menu, then download
  SVD1950ModbusRedunant.pdf from the Modbus TCP
  folder.

  click on Show New
• Select IP Address Fail To instrument. In
  dialog, enter primary and secondary IP addresses
  for HC900 specified as
• ltPrimary IP AddressgtBltSecondary IP Addressgt

• Driver Commands (Specview Configuration mode)
• The following driver commands can be entered into
  the commands listing for TCP/IP Com Port Setup.
  See supporting Tech Note for more detail on these
  and other commands.

For full fault tolerance
For automatic fail-back to primary network

• Failover Options
• Default Fail to secondary network when primary
  fails, only fail back to primary if secondary
  fails
• Driver Command Entry None, this is the default
  case
• Fail Back to Primary After failover to
  secondary network, monitor access to primary
  network and fail back to primary network when
  available
• Driver Command Entry TCPFAIL2PRI 1
