The Chariot Gateway is a FREE software protocol converter that runs on a Windows 10 Operating system. Any devices with the Windows 10 OS should be able to load the Chariot software and act as a protocols converter. The protocols supported by the Chariot gateway are BACnet IP and Modbus TCP with a maximum limit of 5 points. Once loaded onto a device, the Chariot gateway is a fully flushed protocol converter that can be used in any system to integrate BACnet IP and Modbus TCP devices. This gateway will allow you to take Modbus points, map them onto BACnet and implement a gateway which exposes the Modbus data as BACnet data allowing both read and write operations.
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 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|
