• the basics of Flexbus communication
1.1 System
Overview
The FieldMonitor system is a distributed vibration monitor system that
physically and functionally integrates with distributed I/O,
programmable logic controllers, distributed control systems, and PC-
based control systems. The system is used with the Allen-Bradley Flex
I/O or Flex Ex distributed I/O products and communicates over
industry standard networks using Allen-Bradley and third-party Flex
I/O network adapters or Flex Ex serial bus isolator and network
adapters.
A distributed vibration protection system is an alternative
to larger rack-based systems or vibration transmitters
when…
• the vibration protection system integrates with a
machine control system that uses distributed I/O over
appropriate networks,
• vibration parameters display on the Human Machine
Interface (HMI) for the machine control system,
• you want local, “on-skid” mounting,
• it is more efficient and economical to connect vibration
points to a distributed FieldMonitor systems than to wire
all points to a central rack-based system,
• the application can benefit from proper connectivity to
diagnostic and machinery management systems,
reduction or elimination of field wiring, and the integrity
and robustness of a system possessing self-check and
self-contained alarm capabilities, or
• protection over a network is acceptable.
