Network connection

PROFIBUS network connections are made to the terminal block
on the AWT210 Communication module.
WARNING – BODILY INJURY
• Refer to the AWT210 Operating Instruction
(OI/AWT210-EN) before making electrical
connections.
NOTICE
Property damage
When connecting an AWT210 to a PROFIBUS-PA network:
• Use cable that meets PROFIBUS specifications for
reliable communications
• Ensure a PROFIBUS active terminator is fitted to
each end of each bus segment.
• Route data lines clear of the source of any strong
electrical and magnetic fields.
