Operation - ABB ETL600 Instruction Manual

ETL600
A further valuable feature of the ETL600 network protocol is the
possibility of connecting several PCs at various points to a network. In
Fig. 4-8, in addition to the PC in the control center, another PC has
been connected to the management port of terminal B1 in substation
B. The network will transport independently all HMI600 messages
between the PCs and all the terminals attached to the network. This is
achieved by entering a network address similar to the equipment ID
into the HMI600 running on the PCs. Permissible values for PC
network addresses are from 65001 to 65500, to be entered into the
HMI600 dialog box Options / Communications / Address of
HMI600.
For supervision of the whole network, the function Alarm polling can
be used accessible under the Network menu. This function works also
for a mixed network of ETL500 Rel.3 and ETL600 links.
