system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
Freelance 800F DigiVis Operator Level
DigiVis operator stations use PC hardware, either standard commercial
Business PCs can also be industrial-grade PCs and run on Micro-
under soft Windows operating system. DigiVis supports dual-screen display operation
operating technology, that is to say, two operations can be performed using one PC
station and operate with a mouse and a keyboard.
Operator level can install one engineering station and several operators

The system is now configured in the office and on site. Operator-level PC
Can also be used as an engineer station. Engineer standing during system uptime
Intervals can be closed without a permanent connection to the system.
