be placed in the system log. Range 4 to 600 seconds. Default 30 seconds.
UTC Type 2 Required NTP accuracy (milliseconds)
This is the synchronisation accuracy which must be achieved by NTP before the
outstation will start timestamped control-reply operation. Range 100 to 1000mS.
Default 500 mS.
UTC Type 2 Optimise Data Transmission
When enabled the OTU will not transmit successive duplicate SCOOT data.
When connected to a Siemens instation this should be enabled. When
connected to a PEEK instation it should be disabled.
Simple UTC Control Timeout (seconds)
Simple UTC control message timeout, in seconds. If no control message is
received from the instation for this period of time, then the outstation drops off
UTC control. Range 3 to 30 seconds. Default 4 seconds.
