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.
