SMA Gateway

SMA to BACnet IP, Modbus RTU, Modbus TCP, and Web Gateway.
The Web (HTTP, XML, REST, Json, COSM) driver allows the Gateway to push data to the Web via a variety of Protocols.
The BACnet IP Driver allows the Gateway to transfer data to and from devices over Ethernet UDP/IP using the BACnet IP protocol.
The Modbus RTU driver allows the Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.
The SMA driver allows the Gateway to read data from a SMA Sunny Webbox over Ethernet TCP/IP.
The Modbus TCP driver allows the Gateway to transfer data to and from devices over Ethernet TCP/IP using the Modbus protocol.

The SMA Webbox Driver allows the Gateway to poll a SMA Sunny Webbox for real time data. The driver can be configured to read Inverter and Sensor Box values.

The Gateway connects to the Sunny Webbox, reads data and stores it internally. When a remote system requests data, this data is served in a form that is appropriate to the protocol, as Modbus, BACnet or Web data. The gateway supports all these options simultaneously. Use the data you want and ignore the other.

The driver is an Ethernet driver that uses Ethernet cables and a hub or a switch to connect between the Gateway and the Sunny Webbox. The Sunny Webbox must be connected to the same network as the Gateway.

Web (HTTP, XML, REST, Json, COSM) Driver

The Web Diver allows for data to be monitored by remote systems running applications that can issue HTTP or SOAP/XML GET requests – such applications can be easily developed by end users. Of course, this data is available using an Internet Browser such as Internet Explorer or Google Chrome

BACnet IP Driver

The CAS BACnet IP driver allows the CAS Gateway to transfer data to and from devices over Ethernet UDP/IP using the BACnet IP protocol.  The CAS Gateway can either be a Client, reading and storing values from a BACnet device, or a Server, making data available as BACnet objects.

The CAS BACnet IP Driver supports the following BACnet Services:

- Who-Is- Who-Has
- Read Property- Read Property Multiple
- Write Property- Write Property Multiple
- Subscribe COV     - Time Synchronization

Note: Chipkin is always updating the BACnet IP Driver. For a recent list of supported services, please visit www.chipkin.com or contact us. If there are services that you require that are not listed, please contact us to discuss how we can add them to the driver.

Modbus RTU Driver

The CAS Modbus RTU driver allows the CAS Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.  The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.

The CAS Modbus RTU Driver supports the following Modbus Functions:

- 01 (0x01) Read Coils- 05 (0x05) Write Single Coil
- 02 (0x02) Read Discrete Inputs- 06 (0x06) Write Single Register
- 03 (0x03) Read Holding Registers- 15 (0x0F) Write Multiple Coils
- 04 (0x04) Read Input Registers- 16 (0x10) Write Multiple Registers

SMA Driver

The CAS SMA driver allows the CAS Gateway to read data from a SMA Sunny Webbox over Ethernet TCP/IP. The CAS Gateway can connect to a SMA Sunny Webbox to read and store data from the SensorBox or from various Sunny Invertor, Sunny Island, and Sunny Tripower devices. This driver only supports read-only functions and cannot command or configure the SMA devices.

Modbus TCP Driver

The CAS Modbus TCP driver allows the CAS Gateway to transfer data to and from devices over Ethernet TCP/IP using the Modbus protocol.  The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.

The CAS Modbus TCP Driver supports the following Modbus Functions:

- 01 (0x01) Read Coils - 05 (0x05) Write Single Coil
- 02 (0x02) Read Discrete Inputs- 06 (0x06) Write Single Register
- 03 (0x03) Read Holding Registers    - 15 (0x0F) Write Multiple Coils
- 04 (0x04) Read Input Registers- 16 (0x10) Write Multiple Registers
