Echo Filter - SICK LMS100 Technische Information

As a time client (NTP) the LMS1xx device is capable of synchronizing with NTP servers. As a time
server the LMS1xx device is capable of being used for time synchronization with other LMSxxx
devices. Each LMS1xx can only act as either time server or time client. The parameterization is done
via the device page Parameter -> System.
If the device is parameterized as time client the following settings need to be set:
The IP address is the one of the server being used for time synchronization. The update time is the
interval in seconds for updating the time from the server. As NTP uses UTC timestamps the time
zone can be used to adapt the system time to the specified time zone.
The values "Max. offset" and "Delay" are read only and can be used for accuracy estimations of the
synchronization.
Time Server
If the device is parameterized as time server, the following points should be considered. Only use the
LMS1xx device as time server for other LMS1xx devices, since the time server functionality of the
LMS1xx device is not a NTP server implementation (although it uses a similar packet structure). Be
aware of additional inaccuracies in time synchronization, if using the LMS1xx device as time server.
This is caused by its system time resolution of 1ms.

Echo filter

The n-pulse-to-1-pulse-Filter is named „Echo filter" starting with V1.60. There are the following
settings:
When the Echo filter isn't activated the first echo is evaluated.
