Figure 20. Isolated Node with Transceiver Powered by the Network.
Isolated Node with
Transceiver Powered by the
Network
Figure 20 shows a node powered
by both the network and another
source. In this case, the trans-
ceiver and isolated (network) side
of the two optocouplers are
powered by the network. The rest
of the node is powered by the AC
line which is very beneficial when
an application requires a
significant amount of power. This
method is also desirable as it does
not heavily load the network.
More importantly, the unique
“dual-inverting” design of the
HCPL-x710 ensure the network
will not “l(fā)ock-up” if either AC line
power to the node is lost or the
node powered-off. Specifically,
when input power (V
DD1
) to the
HCPL-x710 located in the
transmit path is eliminated, a
RECESSIVE bus state is ensured
as the HCPL-x710 output voltage
(V
O
) go HIGH.
*Bus V+ Sensing
It is suggested that the Bus V+
sense block shown in Figure 20
be implemented. A locally
powered node with an un-
powered isolated Physical Layer
will accumulate errors and
become bus-off if it attempts to
transmit. The Bus V+ sense
signal would be used to change
the BOI attribute of the DeviceNet
Object to the “auto-reset” (01)
value. Refer to Volume 1, Section
5.5.3. This would cause the node
to continually reset until bus
power was detected. Once power
was detected, the BOI attribute
would be returned to the “hold in
bus-off” (00) value. The BOI
attribute should not be left in the
“auto-reset” (01) value since this
defeats the jabber protection
capability of the CAN error
confinement. Any inexpensive low
frequency optical isolator can be
used to implement this feature.
