Default: 120 seconds

This setting specifies a time delay for the detection of dead network TCP connections. If

there is no data traffic on a DNP TCP connection for greater than the time specified by

this setting, the connection is aborted by the D90

Changes to this setting takes effect after power has been cycled to the relay.

The binary and analog inputs points for the DNP protocol can configured to a maximum of

256 points. The value for each point is user-programmable and can be configured by

The DNP point lists always begin with point 0 and end at the first "Off" value. Since DNP

point lists must be in one continuous block, any points assigned after the first "Off" point

are ignored.
