2.5.2 Functions of a service session
Description of functions
The following functions are available during a link with the machine control. These
functions enable diagnostics and fault rectification via the machine control. It is
usually up to the service technician to execute the function. The technician can
work on all problems via remote access on a PC with a mouse and keyboard.
Several service employees and specialists can work together in a service session
to solve a problem. The service technician who establishes the service session first
keeps control of all functions throughout the service session. All other service
technicians can only observe what is going on. If necessary, the first service
technician can pass on and take back control to or from another service technician
within a desktop control session.
The entire session can also be passed on to a second service employee.
