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