Hi,
When you say “…address have been configured on both ends to match”, do
you mean that you set the ‘Interface MAC ID’ of the dialog that comes
up when you start Simple Who to the one that is used by the Eurotherm
2404 Controller?
Simple Who is a master/scanner in a DeviceNet network, thus the
‘Interface MAC ID’ you configure is the one of the master, which must
not be identical to the one of any slave devices in the network. So,
try setting the ‘Interface MAC ID’ to a value other than the one used
by the Eurotherm 2404 Controller.
