Chipkin's HTTP IoT to Modbus or BACnet IP Software Gateway is a Windows-based protocol converter. The gateway operates by reading the data from devices that use HTTP IoT. The values read from these sensors then can be read from a Modbus or BACnet IP network.
The gateway requires minimal configuration and can be considered a "plug and play" component of any network system. It's ready to operate out of the box and can be installed without an engineer's approval.
CAS2500 - Windows
This device is a Software version of our Data Client/Logger and Gateway. It is compatible with an hardware that can load Windows 7 or 10. It allows you to turn any PC that meets the minimum requirements into a Data Client/Logger and Gateway.
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.
Web (HTTP, XML, REST, Json, MQTT) 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
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 |
