IP ADDRESSING
There are some SCADA PLC protocols that use different IP addressing modes. GE’s Global
Data protocol has the ability to send out a group message command to remote PLCs. The
group message is actually a multicast message. The Multicast feature allows the user to
add or delete a remote’s IP address.
