SMA Gateway Description

Page 6 of 62

The SMA Gateway connects to a SMA Sunny Webbox via an Ethernet (TCP/IP) connection. The SMA

Gateway can then be configured to poll for data values from a number of devices that are connected to the Webbox. These devices can be Sunny Invertors, SensorBox, or Sunny Islands.

After configuration, the Gateway will poll and read the data from the SMA devices and stores it internally. When a remote system requests data, this data is served in a form that is appropriate to the requesting protocol (Modbus TCP/RTU or BACnet). In the event that the connection to the SMA

Webbox is lost, or data cannot be read, the gateway can signal this to the remote data clients by changing all the values currently stored to a predefined default value.

The Gateway requires configuration that will be described later in this document.

Limitations and Best Practices

Page 9 of 62

Maximum Number of SMA Sunny Webboxes per Gateway

Only 1 SMA Sunny Webbox can be connected to a single gateway.

RS232 Best Practices

We recommend a maximum of 30ft for the RS232 cable. A well-made cable in a clean environment can easily run to 100ft and provide satisfactory performance.

Configuration and Settings

Page 10 of 62

3.1.

SMA Sunny Webbox Connection Settings

To poll for data from a Sunny Invertor, Sunny Island, or SensorBox all that is needed is the IP address of the Sunny Webbox that these devices are connected to.

3.2.

SMA Sunny Webbox Configuration Options

The following options are set to determine how the data from the SMA devices is handled.

- Night Data – SMA Invertors turn off at night. By enabling this option and selecting one of the Night data methods, empty values will be replaced with either a zero value or the last successfully polled value.

- Night Data Method o Use Default Value – Uses the supplied default value to represent Invertor data at night.

o Use Last Polled Values – Uses the last successfully polled Invertor data to represent

Invertor data at night. If no such data is available, the supplied default value is used.

- Default Value – The value that all points are set to initially and when the device is disconnected or offline.

3.3.

ModbusTCP Settings

To connect using ModbusTCP you need to know the IP address of the gateway and the Modbus

‘Station’ number (also known as ‘Device Address’ or ‘Node ID’) and the TCP Port for the connection.

The following are the configurable parameters for this connection:

Modbus Station Number (Default value is 1)

Modbus TCP Port (Default value is 502)

Review section 7.6 Another Method for Changing the IP Address - DHCP to see the default IP

Address settings and how to change them.

3.4.

ModbusRTU Settings

To connect using ModbusRTU you need to set the connection parameters correctly and the

Modbus ‘Station’ number (also known as ‘Device Address’ or ‘Node ID’)

- Modbus Station Number (Defaut value is 1)

- Connection Parameters : o Baud Rate – 1200, 2400, 4800, 9600 (Default), 19200, 38400, 76800,

115200 o Data Bits – 8 (Default), 7 o Parity – None (Default), Odd, Even o Stop Bits – 1 (Default), 2

3.5.

BACnet IP Settings

Page 12 of 62

BACnet supports discovery. Thus any BACnet tool will discover the gateway and report its properties. Each gateway must be allocated a unique device instance number and thus this is a configurable setting.

The configurable BACnet IP connection settings are:

Device Instance Number (Default value is 389001)

Port

Network

(Default value is 47808)

(Default value is 0)

It is important to note that BACnet messages cannot pass from one subnet to another without a

BACnet technology called BBMD installed. The easiest installation and the best way to avoid this complication is to set the gateway’s IP address so that it is on the same subnet as the BACnet data client (usually the BAS / Scada system).

Review section 7.6 Another Method for Changing the IP Address - DHCP to see the default IP

Address settings and how to change them.

3.6.

Reading Data using HTML / Web Browser

Page 16 of 62

Use a Web Browser to browse to this page. http://192.168.1.113/bin/sma/report

This is the IP address of your gateway

You are presented with a screen similar to this one.

This screen is useful for seeing the current BACnet and Modbus mappings as well as the current value of the data point, which is useful for quickly checking that the connections are good and data is being read.

Reading Modbus Data

Need to know more about Modbus? Read this guide. http://www.chipkin.com/september-2010-newsletter

Page 17 of 62

5.1.

Modbus Function Supported (RTU and TCP)

The Gateway supports functions 1, 2, 3, and 4. Most masters should be configured to use function 3 (Read Holding Registers). However it will respond to polls that use the other functions with offset equal to zero. You can read this data as 3xxxx, 1xxxx, 0xxxx or 4xxxx data.

5.2.

SMA Modbus Data Map

For the following registers, each set of data (Invertor, SensorBox, and Sunny Island) will be described as if it was the first device configured. Each additional device added will be offset by

100. So the first device will have data starting at 40001, the second device will have data starting at 40101, the third device will have data starting at 40201, etc.

Interpreting Modbus Data

Page 25 of 62

Modbus does not have a mechanism for reporting the validity of data. What happens if the gateway loses its connection to the SMA Webbox? After a timeout period has elapsed the gateway will regard the data it had read previously, as unreliable.

The remote data client will see the value 65535 (-1, configurable) in the registers that contain unreliable data. In other words, rather than serve the old (possibly obsolete) data, the gateway serves a value that clearly identifies that the data is invalid.

If you require the data as floats, please contact Chipkin Automation Systems to update the configuration and Modbus map. These values will be encoded as IEEE754 format floating point numbers. These values use 2x 16bit registers. They are clearly identified in the Modbus Map.

Since Modbus does not support floating point numbers so all other values are served as whole numbers.

5.4.

Test Procedure – Use CAS Modbus Scanner

Page 26 of 62

You can test the ModbusTCP data using free test software provided by Chipkin

Automation Software.

This is a link to the download page. http://www.chipkin.com/cas-modbus-scanner

Configure the scanner as follows

1.

Add a connection – specify the IP address of the gateway

2.

Add a device to the connection. Set the device=1

3.

Add a Request to the device: Read Holding register offset=1 Length=68

The result should be like this.

Reading BACnet Data

Page 29 of 62

BACnet supports discovery. When you discover the gateway, objects and properties you will find appropriately named objects that report data from the SMA Devices. Because BACnet supports discovery, usually knowledge of the BACnet Device Instance Number does not need to be known in advance.

Each BACnet device (like the gateway) needs to have a unique instance number. Therefore it may be necessary for you to change the instance number.

Need to learn some BACnet basics? Read this guide. http://www.chipkin.com/bacnet-solutions

6.1.

Most Common BACnet Problem

If the device or application that is reading the BACnet data is on another subnet then it will not discover or be able to talk to the gateway. This can be resolved two ways. 1. Change the IP address of the gateway to be on the same subnet – a simple task. 2. Install BBMD – a non trivial task – but a task you can often pass the buck on – it is the responsibility of the company installing the BAS system to provide BBMD. You can read more about it at this link. http://www.chipkin.com/articles/bacnet-bbmd

6.2.

Interpreting BACnet Data

If the gateway loses communications with the Veeder Root device or if a data point cannot be read from the controller, the ‘Out of Service’ property of the data object is set true once the timeout has expired. The value of the ‘Present Value’ property is not changed, thus the last good value will be shown.

6.3.

BACnet Objects

The following is a list of possible BACnet Objects. Note : This list only contains what is configured with the default configuration (four tanks and system alarms).

2014


Tel: (866) 383-1657, Fax: (416) 915-4024


Page 30 of 62

For the following BACnet objects, each set of data (Invertor, SensorBox, and Sunny Island) will be described as if it was the first device configured. Each additional device added will be offset by 100. So the first device will have data starting with analog-input 1, the second device will have data starting at analog-input 101, the third device will have data starting at analog-input 201, etc.

Commissioning, Diagnostics and Trouble Shooting

Page 44 of 62

7.1.

What to Take to Site for Commissioning

1.

The gateway and other supplied components.

2.

USB->485 Converter

Any will do. This will allow you run tests using the 485 serial connection for Modbus RTU.

Connect to the device and find out which COM port is now available, use CAS Modbus

Scanner to retrieve data.

3.

Serial Cables

A Null Modem cable is used to connect to the gateway diagnostic port. Take one with you.

4.

Laptop

5.

Gateway IP Address Allocation Tool

Download from http://www.chipkin.com/articles/cas-gateway-ip-address-tool

6.

Wireshark packet sniffer software – free download http://www.wireshark.org/download.html

7.

CAS Modbus Scanner – free download

CAS Modbus Scanner is a utility to retrieve coils, inputs, holding registers, and input registers from a Modbus enabled device. Values retrieved from the device can be viewed in many different formats including Binary, HEX, Uint16, Int16, Uint32, Int32, and Float32. http://www.chipkin.com/cas-modbus-scanner

8.

Serial Mini Tester

Page 45 of 62

9.

DB9 and DB25 male and female connector make-up kits (Solder free)

Always useful but not required if you have tested your cable prior to attending the site.

10.

Rx / TX cross over.


It is useful to be able to swap the conductors connected to pins 2 and 3. Take a module with you. It is easier than changing the wires.

For example, the Ziotek Null Modem Adapter DB25 http://www.cyberguys.com/productdetails/?productid=751&rtn=750&core_cross=SEARCH_DETAIL_SIMILAR#page=page-1

Hub

Used as a last resort if there are problems on Modbus or BACnet

A hub is not a switch. A hub can be used for trouble-shooting whereas only a ‘supervised’ switch can. Most switches are not supervised. http://www.chipkin.com/articles/hubs-vs-switches-using-wireshark-to-sniff-networkpackets

7.2.

Gateway Status

Page 48 of 62

Browse to http://192.168.1.113/bin/sma/report and you will the present values of the data points

If all of the data values are displayed as “-1” (or whatever the configured default value is) then it could mean one of two things.

1) The Gateway has just been configured and has begun to poll for values.

Wait for a little while for the first couple of scan intervals to finish, and then refresh the page. Current correct values should be displayed.

2) The Gateway is not connected to the Veeder Device. Either the Gateway was never connected, or the Gateway got disconnected from the device.

After an amount of time has passed (as configured in the Disconnect Time parameter of the configuration), the Gateway will set all values to the default value.

You must manually refresh this page to get the updated values.

7.3.

Gateway Diagnostics

Power Led: Green Solid = Normal Condition.

RJ45 LED: Green to show link.

7.4.

Debug log.

Page 49 of 62

The debug messages are sent on UDP port 514 to the broadcast IP address:

{255.255.255.255} as plain ASCII text. You can use "logview4net" tool to view and recorded the debug messages as they are sent from the device.

Logview4net

Free and open source tool built to viewing and monitoring logs. It works with many different file formats and protocols including UDP. This tool can be download for "free" from the publishers website http://logview4net.com/

Click Done

Operating Normally

Occasional timeout messages should be tolerated.

Normal Operation.

7.5.

Veeder Device Connection

Use a mini tester to check the serial ports.

Connect the cable to the Veeder device only – RD should be green. If it isn’t this means the cable to the Veeder device is wrong or the port isn’t working.

Connect the cable to the gateway only – TD should be green. If it isn’t this means the cable to the gateway is wrong or the port isn’t working.

During normal operation RD will flicker green/red

7.6.

Another Method for Changing the IP Address - DHCP

This device supports DHCP and DHCP is disabled.

When shipped the device

IP = 192.168.1.113

Mask = 255.255.255.0

Gateway = 192.168.1.1

Page 53 of 62

If you simply want to change the IP address then use the simpler method provided in section 3.6

Change Configuration Settings.

A tool is provided to change the IP address of the gateway. The tool can be downloaded from: http://www.chipkin.com/articles/cas-gateway-ip-address-tool

When you start this tool it discovers gateways and list them in the right had side ‘Select a Unit’ area. If the area is blank then click the ‘Search Again’ button. If it remains blank check that the

Ethernet connection is made – is there a green link LED on the RJ45 and on the hub/switch you are connected to.

2014


Tel: (866) 383-1657, Fax: (416) 915-4024


Page 54 of 62

To change the IP address complete the Fields and click the ‘Set’ button.

Please set the IP, Network Mask, and Gateway fields.

To set it to DHCP, simply put all fields to 0.0.0.0 and click the ‘Set’ button.

7.7.

Discovering the Gateway

Use the tool provided to change the IP address to discover the gateway and learn what its preallocated IP address is. See section 7.6 Another Method for Changing the IP Address
