Connection modes

Types of connections

The user can establish two different types of connections to a chromatography system:

  • Control mode connection: The user is able to actively control the system.

  • View mode connection: The user can monitor the system activity but cannot control the system.

Several simultaneous connections can be established to one system, but only one may be in control mode. The other connections are in view mode.
