CAS 2700-02B Veeder-Root Gateway

The CAS 2700-02 Veeder-Root Gateway can poll Veeder-Root TLS Panels for status, real-time, and configuration data. The Gateway can be used to read Tank Inventory, System Status, Tank Alarms, Sensor Alarms and more. The Veeder Gateway serves data from a TLS panel 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 TLS Panel, 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 TLS Panel is lost, or data cannot be read, the gateway can signal this to the remote data client.

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 Veeder-Root drivers support using a RS232 serial port or TCP/IP Ethernet to connect between the Gateway and the TLS Panel. The Panel therefore must have a suitable RS232 card or Ethernet card installed.

Supported Veeder-Root TLS350 Commands

The following is a list of the Veeder-Root TLS350 Protocol Commands that the CAS 2700-02 Gateway supports:

  • 101 - System Status Report
  • 201 - In-Tank Inventory Report
  • 202 - In-Tank Delivery Report
  • 406 - Relay Status Report
  • B38 - Vacuum Sensor Diagnostic Report

Note: The CAS 2700-02B Veeder-Root Gateway does not support any functions that can configure or change settings on the Veeder-Root panels. As such, all data points that the Gateway makes available via Modbus, BACnet, and Web requests are read-only.
