The Danfoss Gateway connects to a Danfoss systems and poll for real time data. The CAS Gateway serves data from a Danfoss system as Modbus, BACnet or Web data. The gateway supports all these options simultaneously. Use the data you want and ignore the other.
The Gateway connects to the Danfoss system, 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.
The driver is a Ethernet driver that uses Ethernet cables and a hub or a switch to connect between the Gateway and the Danfoss system. The Danfoss system must enable and support the XML Interface.
CAS Hardware 700
The CAS 700 Hardware device contains 2x 9-pin serial ports (1x RS485 and 1xRS232), and one Ethernet port. The device also contains a microSD card where system files, assets, configurations, and logs are stored.
The device has the following system drivers that can be enabled:
- HTTP REST Server - a passive web server with an API that users can interact with the device to get or set values
- HTTP Push Driver - a driver that can be configured to push data in a specific format (JSON, XML, CSV) to a 3rd party web server. Current data formats are Chipkin's default JSON payload and VeederRoot Tank data as JSON. Please contact Chipkin for information on adding additional formats.
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 |
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 |
