Connection security

The purpose of connection security is to avoid conflicts regarding system control, so that only one user at a time controls the chromatography system.

Two kinds of connection modes can be established with the UNICORN system:

• Control mode connection: The user has full system control, that is control of the chromatography system.

• View mode connection: The user can view the process but not control it.

To prevent conflicts, the system can have only one control mode connection at a time, that is only one user at a time can control the process.

To prevent other users from establishing a control mode connection to the system, a user should

• establish a view mode connection to the system

• lock the system with a password. This password can be different from the user’s logon password.

It is recommended that systems are always locked when a user leaves the system. When the system is controlled and locked, the responsible user is identified in the System Control window for view mode connections. A system which is left unlocked with no control mode connection has no identified responsible user.

Systems may be locked even when they are idle, to allow users to reserve a system for later use.
