Supported DeviceNet features
The FX0-GDEV supports the following functions of a DeviceNet Group 2 slave (server):
Explicit Messaging (fragmented)
Implicit Messaging (I/O messages)
– Poll I/O (fragmented)
– Change of state I/O (fragmented)
– Cyclic I/O (fragmented)
Unconnected Explicit Request Messages (pre-defined master/slave connection set)
Device heartbeat and shutdown messages
UCMM port (Unconnected Message Manager)
Duplicate MAC ID messages
Offline Connection Set
Pre-defined master/slave connection set
The FX0-GDEV supports a pre-defined master/slave connection set that makes it possible
to establish a DeviceNet connection that requires fewer network and device resources.
This set contains an explicit messaging connection and makes possible several different
I/O connections, including Poll, COS and Cyclic.
Poll I/O messages
The Poll command is sent by the master. A Poll command is directed at a single, specific
slave (point-to-point connection). A master must send a dedicated Poll command to each
slave that is to be polled. On the receipt of the Poll command the slave replies to the
master with an I/O message.
