OPW Gateway

OPW to BACnet IP, Modbus RTU, Modbus TCP, and Web Gateway.
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 TCP driver allows the Gateway to transfer data to and from devices over Ethernet TCP/IP using the Modbus protocol.
The Web (HTTP, XML, REST, Json, MQTT) driver allows the Gateway to push data to the Web via a variety of Protocols.
OPW driver allows the Chipkin Gateway to read data from an OPW Fuel Management System over RS232 serial port.
The Modbus RTU driver allows the Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.

The OPW Fuel Management Systems Gateway uses the Veeder Root TLS 350 protocol to poll for status, real-time and configuration data. Thus the driver can be used to read Tank Inventory, System Status, Tank Alarms, Sensor Alarms and more.

The Gateway connects to the OPW Fuel Management 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. In the event that the connection to the OPW Fuel Management System is lost, or data cannot be read, the Gateway can signal this to the remote data client.

The Gateway serves data from an OPW Fuel Management 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 requires minimal configuration and can be considered a plug and play component of a system, in that it is ready to operate out of the box with the default configuration.

The driver is a serial driver using an RS232 serial port to connect between the Gateway and the OPW Fuel Management System. The Panel must have a suitable RS232 card installed that can support the Veeder Root TLS 350 protocol.

The CAS OPW Gateway supports and has been tested with the following Products:

  • SiteSentinel® Integra 100™ Console
  • SiteSentinel® Integra 500™ Console
  • SiteSentinel® iSite™ Console
  • SiteSentinel® Nano® Console

The CAS Franklin Fueling Gateway supports, but has not been tested with the following Products:

  • SiteSentinel® iTouch™ Console

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

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

OPW Driver

The driver is a serial driver using an RS232 serial port to connect between the Gateway and the OPW Fuel Management System. The Panel must have a suitable RS232 card installed that can support the Veeder Root TLS 350 protocol.

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
