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.

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

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

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
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

Check “Include
Name” to provide
name text for
Variable selected
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)

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.

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
Specview’s FTP site.
• Go to www.specview.com, choose ‘Tech Notes’ from the ‘Support’ menu,
then download SVD1950ModbusRedunant.pdf from the Modbus TCP
folder.

• 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
