For multi‑user systems, standard CMS stations are to be used in combination with different options for remote access of data from different locations. Such options are mainly used for large cranes in the harbor terminals where several persons operate the system at the same time.

Remote access to the local CMS stations is also possible, this is also referred to as "Remote CMS" (RCMS) in the cranes sector. In the case of large crane systems, this is usually performed in a central maintenance building. In case of a fault, diagnostics information can be called up beforehand. In the best case scenario, a fault can be rectified in this way.

Use of several cranes with remote access

Example of requirements for SIMOCRANE CMS:

• Acquisition of productivity data and archiving
• Alarm/event reporting system with archiving
• Error logs and productivity data logs
• Replay of crane data (playback function)
• Visualization of the crane and individual components
• CMS computer is installed in the electrical room
• Crane driver must have an operator panel in the cabin
• Remote access must be possible from a maintenance building

Solution:

• SIMOCRANE CMS Lean with one (1) WebClient
  Article No. 6GA7214-1AA00-0AA0
  or
  SIMOCRANE CMS Basic with one (3) WebClients
  Article No. 6GA7214-1AB00-0AA0
• Panel PC 477 as operator panel for the crane driver and in
  the checker cabin, e.g.: Article No. 6AV7240-6DD17-0PA0
• Rack PC 647 as the CMS PC in the electrical room, e.g.:
  Article No. 6AG4112-2GP30-0BX0
• Standard PC in the maintenance building with remote crane access via Internet Explorer (Web)
