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

7 File Number- 7


• 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 File Number- 8


• 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 File Number- 9


• 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 Variableslists show all listed by number (forreference) and tag name,data type pre-assigned asAnalog or Boolean (digital), readonly or read/write

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

Uncheck “IncludeName “ to not includetext

10 File Number- 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 File Number- 11


• Adding a control to Custom map (all paremeters)

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

12 File Number- 12


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

Browse and select

13 File Number- 13


• 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

- 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 toVariables

HC900 Redundant Ethernet Network Support

Primary network

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)

Secondary network

17 File Number- 17


• 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.

• 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 File Number- 19


• To view active network in use:- Place Active IP address variable on a display

20 File Number- 20


• 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-backto primary network

21 File Number- 21


• 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
