Tankvision Basic safety instructions

2 Basic safety instructions

2.1 Requirements for the personnel

The personnel for installation, commissioning, diagnostics and maintenance must fulfill the following requirements:

• Trained, qualified specialists: must have a relevant qualification for this specific function and task

• Are authorized by the plant owner/operator

• Are familiar with federal/national regulations

• Before beginning work, the specialist staff must have read and understood the instructions in the Operating Instructions and supplementary documentation as well as in the certificates (depending on the application)

• Following instructions and basic conditions

The operating personnel must fulfill the following requirements:

• Being instructed and authorized according to the requirements of the task by the facility's owner operator

• Following the instructions in these Operating Instructions

2.2 Designated use

2.2.1 Application

Tankvision is a dedicated tank inventory management system. Components:

• Tankvision Tank Scanner NXA820 scans parameters from tank gauges and performs tank calculations

• Tankvision Data Concentrator NXA821 summarizes data from various Tank Scanners NXA820

• Tankvision Host Link NXA822 provides data to host systems (such as PLC or DCS) via Modbus

The above mentioned components are operated via a standard web browser. It does not require any proprietary software. Tankvision is based on a distributed architecture on a Local Area Network (LAN). Due to its modular structure it can be adjusted to any application. It is ideally suited for small tank farms with only a couple of tanks, but also for large refineries with hundreds of tanks.

Tankvision User access rights

5 User access rights

The Tankvision system has an inbuilt authentication mechanism to prevent unauthorized access. The system identifies the user by a unique logon name and password. The system records all the activities performed by each user and allows only a specific number of users from each user type to be logged in at the same time. This can be configured in system settings by an authorized entity. Each Tankvision unit has an option to confine user access rights data for local use within the unit or enable user access rights data for the central Tankvision unit thereby allowing the user to access all the units that are configured to the central Tankvision unit.

All in this manual described functionality is based on the default settings for the role of the "Operator". The operator is not allowed to perform any changes in the user access rights. In case the "Operator" is allowed to perform other operations than the ones specified with the default settings refer to the "Description of Instrument Functions" ­BA00339F/00/EN.

NXA82x_Manage-User-Group-Access -Rights
