USING TIME MANAGEMENT
CRIMSON USER MANUAL - MODULAR CONTROLLER
CONFIGURING THE TIME MANAGER
The various properties associated with configuring the time management facilities are
accessed via the Time Manager icon in the Communications window…
The properties are detailed below…
• The Enable Time Manager property is used to control access to the other
facilities. If it is not checked, Crimson will operate in local time and will have no
knowledge of time-zones or other time management information.
TIME SERVER
Crimson 2.0 can act as an SNTP server by selecting yes in the Time Server Enable SNTP
drop down selection box. This will allow other Red Lion products to synchronize their own
clocks to the clock of this unit. The IP address of the server when programming the client is
the Ethernet port IP address programmed in Crimson 2.0. Note that Crimson’s
implementation of SNTP is not fully RFC compliant, and is not supported as a source of
synchronization for non-Red Lion clients.
TIME CLIENT
Crimson 2.0 can act as an SNTP client by selecting yes in the Time Client Enable SNTP drop
down selection box. The operator interface will then attempt to synchronize its clock with
another Red Lion product, or to another SNTP time source such as a server on the network.
For example, Windows XP Pro is an SNTP server.
• The Linked DST property is used to instruct the SNTP client to attempt to read
the current Daylight Savings Time setting from the SNTP server. As this facility
is not a standard part of the SNTP protocol, it will only operate if another Master
or G3 operator panel is specified as the server. The facility is useful, in that it
allows the Daylight Savings Time adjustment to be made via a single device on
the factory network, with the other devices then following the central setting.
• The SNTP Mode and SNTP Server properties are used to configure the IP
address of the Simple Network Time Service server. If Configured via DHCP is
