Using DH-485 WHO
When configured for a DH-485 network, you can use WHO with any of the SLC
500 processors. When using an SLC 5/03 processor , the current online
configuration must be for a DH-485 device in order for Who Active and Who Listen
to be available. When using an SLC 5/04 processor , the current online
configuration must be for a DH-485 device or your system must be configured for
Interchange DH-485.
DH-485 WHO Listen
The Who Listen function shows you active nodes without placing your terminal on
the network. You cannot change a node’
s status from this display .
“Listening” is done at the baud rate selected in the online configuration function.
Asterisks appear next to active nodes. If no asterisks appear in the table, it may be
because:
• either you are listening at a baud rate different from that of the network devices,
or
• there are no initiators present on the network.
