4.2 Field Controller PS
Industrial” 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
