Modbus TCP/IP Integration with the i-Vu Link You can integrate Modbus TCP/IP devices into an i-Vu CCN system with a i-Vu Link acting as a client device.

i-Vu Link

Modbus port E1 10/100 BaseT Ethernet

Module driver Modbus: drv_ivulink_modbus_ .driver *

Read/write capability Can read from and write to the third-party equipment

Integration points supported 500

Third party

Supported equipment Any device that supports the Modbus TCP/IP protocol

Network media type Ethernet

Quantity of devices you can physically connect to i-Vu Link's Ethernet port

Up to 30 Modbus TCP/IP connections. Connections could be to a Modbus TCP/IP server device or to a Modbus TCP/IP server device that is acting as a Gateway to other Modbus serial devices. Each Modbus TCP/IP server gateway can have one serial modbus slave connected over EIA-232, or up to 247 modbus slaves connected over EIA- 485.

* The i-Vu Link driver supports Modbus devices connected to Port S2 and BACnet or Modbus devices connected on the Ethernet port simultaneously. The third-party point count for the i-Vu Link is the total of the 2 ports.

Overview

The integration process

2 Modbus TCP/IP

Follow the steps in this document to integrate one or more third party Modbus TCP/IP devices into an i-Vu CCN system using an i-Vu Link. To install and network the i-Vu Link, see the i-Vu Link Installation and Start-up Guide.

1 Create custom equipment in ApplicationBuilder

1 Start ApplicationBuilder.

2 Select equipment type:

CCN Values Only - to read and write values on the CCN network and to display those points on a graphic

Integration Values Only - to read and write values from the third party network and to display those points on a graphic

CCN Link Integration - to share values from the third party network with the i-Vu Link on the CCN network and to display those points on a graphic

3 Click Next.

4 Type a name for the custom equipment (i.e., Hot Water System).

NOTE The name must not exceed 21 characters!

5 Enable English or Metric units.

6 Choose engineering options for your application (Schedule and Setpoint, Runtime, etc..)

7 Click Next.

8 Add Elements to your application.

NOTE Elements are a collection of input/output points that perform a specific operation. The input/output point that is reading or writing to the Modbus TCP/IP network is called an integration point. Integration points may be used in conjunction with CCN points to share data between the Modbus TCP/IP network and the CCN network.

The available Elements that you can add to your custom equipment in ApplicationBuilder are:

Point typeUsed for

Read CCN Point Reading an analog or binary value from the CCN network

In: CCN Values, Link Integration

Carrier Text Point Reading Text value from a CCN device

In: CCN Values, Link Integration

Setpoint Write Allows CCN setpoint value to be edited directly from graphic

In: CCN Values, Link Integration

Reading an analog or binary value from the third party device and then writing that value to the CCN network

In: Link Integration

Link CCN Passive Point to Integration Point

Exposing an analog or binary value to the CCN network so that it can be written to the third party network

In: Link Integration

Read Integration Point Reading an analog or binary value from the third party device

In: Read Integration, Link Integration

Link CCN Point to Integration Point

Reading an analog or binary value from a CCN device and then writing it to the third party network

In: Link Integration

Link Integration Point to CCN Passive Point

Reading an analog or binary value from the third party device and then exposing that value to the CCN network

In: Link Integration

Link BACnet variable to CCN Point

Allows an analog or binary value from BACnet to write that value to the CCN network

In: Link Integration

9 As you add Elements, enter the requested information for the integration or CCN points:

Display Text - the name of the point as it will appear in i-Vu CCN (i.e., Frequency)

Reference Base - the name that will be added to each point that makes up the Element, so that all points have a unique identifier (i.e.,input_Freq, trendFreq, output_Freq) - this name must be unique (do not copy and paste)

Input Address - enter the Modbus TCP/IP or CCN address

Define the Modbus TCP/IP or CCN address string using the syntax for each point in the list, as described below:

Input Scaling - enter variables

NOTE Use Scaling when the value you are reading from the Modbus TCP/IP or CCN device needs to be scaled before showing the value on a graphic or trend. Scaling information can be found in the third party points list.

Example: You have an integration point set up to read the motor temperature of a variable speed drive. The third party points list shows that this value will be given in degrees C, but you want to display it in degrees F on a graphic. Therefore, using the formula F = 9/5(C) + 32, the scaling/unit conversion fields for the integration point would be filled out as follows: ([value read] + 0) x 1.8 + 32

Output Address - enter the Modbus TCP/IP or CCN address, as described below.

Output Scaling - enter variables

Continuing the example above, if you wanted the graphic to display values in F, but then you wanted to share that value with the CCN network in C, the scaling for the CCN Passive Point would be:

([value read] + 0) x1 + 0

12 Save Location - browse to a location where you would like to save the new custom equipment.

13 Click Save.

To format a Modbus TCP/IP address

Use the information below to format a valid address in each integration point that you use to read or write to a Modbus TCP/IP device.

CAUTION! When integrating third-party devices into an i-Vu CCN system, most communication problems are caused by incorrect data or typos in the integration point's Address field.

Example: mtcpip://UINT/40128/3/192.168.168.1

To...this kind of value...

use this type of integration point...

If the Modbus register address (sometimes called register, address, code, or parameter) is not in this range, take the number given, then add 1 to coils; add 10,001 to discrete inputs; add 30,001 to input registers (sometimes given as 3X); and add 40,001 to holding registers (sometimes given as 4X).

The Modbus register address must be a decimal value. If you see the letters AF in register addresses anywhere in a points list, use a scientific calculator to convert these hexadecimal values to decimal values.

In rare cases, the number given is not in the range shown above and is greater than 9999. Type a 4 (function code) at the beginning of an input register or a 3 at the beginning of a holding register. For example, to read holding register number 313567, type 413568. (Add 1 as described in the paragraph above.)

2

Each Float has 2 consecutive Modbus register addresses. Use the lower number in the integration point address.

To format a CCN address

There are three different methods for defining the CCN address strings.

1 They can be manually typed in ApplicationBuilder.

2 You can use Copy table point in i-Vu CCN's table interface to copy CCN point information directly from a CCN table to ApplicationBuilder's "ccn://" address field.

3 You can use Map to Point in i-Vu CCN's table interface to map the CCN points from your custom equipment file directly to CCN table data.

NOTE Your custom equipment must already be downloaded in the i-Vu Link to use this method. (Proceed to Assign and download custom equipment in i-Vu CCN (page 7) first).

The integration process

6 Modbus TCP/IP

Method 1: Type the address manually in ApplicationBuilder 1 If you are actively reading or writing a point on a CCN device, then manually type in the CCN device's

address, Table Name, and Point Name that you wish to read or write.

ccn://link/

("link" indicates the CCN device that the custom equipment has been mapped to)

or

ccn:// /

/

Examples:

ccn://link/HWP01-32/TEMP

ccn://0,2/HWP01-32/TEMP

2 If the point is a CCN passive point (i.e, it's just being exposed to the CCN network), then type:

ccn://passive/ , where is the name that you have chosen for this CCN point.

Example: ccn://passive/freq

Method 2: Copy table point in i-Vu CCN 1 Launch i-Vu CCN.

2 Select the desired equipment in the navigation tree.

3 Expand the tables underneath that equipment.

4 Find the specific table and point that you want to read or write.

5 Click Copy in the table interface.

6 Inside of ApplicationBiuilder, hit CTRL-V to copy the CCN address from the table to the "ccn://" address field.

Method 3: Map to point in i-Vu CCN 1 Launch i-Vu CCN.

4 Find the specific table and point that you want to read or write.

5 In the table interface, navigate to the Map to Point column.

6 From the drop-down menu, select the point in the custom equipment that should be mapped.

7 Click OK.

The integration process

Modbus TCP/IP 7

Optional Modbus TCP/IP IP addressing method

If the unit ID of every third-party device in the system is unique, but they all use the same IP address, you can save time by omitting the IP addresses from the individual integration point addresses and mapping the unit ID's to their IP address in i-Vu CCN. See example below.

1 On i-Vu CCN's navigation tree, right-click on the custom equipment that you created in ApplicationBuilder. Select Driver Properties.

2 Select Protocols > Modbus TCP/IP> > IP Addressing.

To edit an integration or CCN point address
