CAS Driver – CAS-2700-02 Veeder TLS 300, 350, 450 Modbus (RTU and TCP) and BACnet and HTML Gateway

Description

The Veeder Serial Driver allows the Gateway to poll Veeder TLS Panel’s 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 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 driver is a serial driver using a RS232 serial port to connect between the Gateway and the TLS Panel. The Panel must have a suitable RS232 card installed.

Driver Operation

The driver can be configured to execute any of the commands in the ‘supported function’ list. The data sent is stored internally in the Gateway and is made available to other protocols (Modbus RTU, Modbus TCP, BACnet IP and HTML) .

The frequency with each data point is read is configurable. The driver retries on errors or timeouts. If the data cannot be read then after some configurable time it is marked as out of service.

The driver reports operating stats and issues on a web page, maintains a log that can be uploaded by HTTP or ftp.

Configuration

Via Web Page. Configure IP settings, Node ID’s, Baud Rate and other parameters.

Users are able to select
Up to 10 Tanks – specify the number and name of each
Up to 10 Sensors – specify the number and name of each
Up to 1 Vacuum Sensor – specify the number and name of each

The names are used to form the names of the BACnet objects and populate the web page showing current values.

Use can specify
ModbusTCP: Node_ID
ModbusRTU: Node_ID, baud, parity, data lengh, stop nits
BACnet: Device instance number, device name.

Communications functions
Supported functions.
Not all Veeder communication functions are supported. The following functions are supported by the Web based configuration. Additional functions are supported but must be configured manually.

COMMAND
101System Status Report
201In-Tank Inventory Report
202In-Tank Delivery Report
203In-Tank Leak Detect Report
B38Vacuum Sensor Report

The driver will not send the next command until a response has been received from the previous or until a timeout has expired.

Support
This driver was developed by Chipkin Automation Systems (CAS). CAS are proud to provide support for the driver. For support please call CAS at (866) 383-1657.
