field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible: supports all international standard open fieldbuses and can be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
Simple engineering: configuration, commissioning and diagnostics using only the same tool CBF (Control Build F) software
mouth
Access to all information from the field including equipment management information
Global database of fieldbus devices, control levels and HMI
