5. 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 File>Export, click on FBD’s, choose “All Modbus Registers”, rename the file as desired, then store in known folder.
For Custom map applications:
In HC Designer, go to File>Export, click on FBD’s, choose “All Modbus Partitions”, rename the file as desired, then store in known folder.

6. Tag Import Configuration Steps – Fixed Map
Connect HC900 to the Specview application via Ethernet, then start Specview
In Specview’s “Configurations Found” dialog, click on “Test Comms for NEW Config” and enter new project file name
In Specview’s “Ports and Protocol’s 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.

9. 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

10. 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):
Add
Browse and select

13. 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.

14. Tag Import Configuration Steps – Custom Map
Sample Custom Map “All Modbus Partitions” file import

15. 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
- Click on ‘Update existing HC900’, enter IP address, then browse for HC Designer export file to update the database for controller
Click choice for naming:
Adds HC900
controller name to
Variables
Omits controller
name

16. 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

17. HC900 Redundant Ethernet Network Support
Technical Note Reference document
A Tech Note is available in the Tech Notes section of Specview’s FTP site.
Go to choose ‘Tech Notes’ from the ‘Support’ menu, then download SVD1950ModbusRedunant.pdf from the Modbus TCP folder.

18. HC900 Redundant Ethernet Network Support
To setup in Specview:
In Configuration mode, access Variables List and click on Show New
Select “IP Address Fail To” instrument. In dialog, enter primary and secondary IP addresses for HC900 specified as:
<Primary IP Address>B<Secondary IP Address>
Click on Create button

19. HC900 Redundant Ethernet Network Support
To view active network in use:
Place Active IP address variable on a display

20. HC900 Redundant Ethernet Network Support
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

21. HC900 Redundant Ethernet Network Support
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
