Next steps to set up OTMC 100
After connecting your OTMC 100 to the network and accessing the device from your computer, you
have to configure your OTMC 100 according to your needs.
See chapter
The OTMC 100 web interface
description of the web interface, or section
page 27 for a description of the most important operating procedures.
Proceed as follows to set up and configure your OTMC 100. Consult your network administrator if you
do not know the correct settings.
1. Configure the network settings.
Open the Configuration section of the web interface and display the Network page (see page
55).
a. Configure the network/IP settings according to the needs of your network. Click the Save All
button to save and apply your settings.
By default, OTMC 100 will attempt to get an IPv4 address via DHCP and assign
an IPv6 address using the automatic configuration. If no DHCP server is
available for IPv4, OTMC 100 uses the zeroconf service to automatically assign
an IP address on its own.
2. Configure the PTP settings.
Display the PTP page of the Configuration section (see page 62). Select your configuration and
click the Save button to save and apply your settings. The most important PTP settings are:
a. PTP profile (General Settings pane): All PTP devices that should synchronize to each other
must use the same profile.
•
Use the Default E2E or Default P2P profile for industrial environments.
Default P2P (peer-to-peer) can only be used if the switches used in the network support
and are configured for operation as peer-to-peer transparent or boundary clocks as defined
in IEEE 1588-2008.
Use Default E2E (end-to-end) if standard switches are used in the network and the higher
synchronization error introduced by these switches is acceptable. The Default P2P profile,
the Power utility profile (according to IEC 61850-9-3:2016), and the Power profiles
(according to IEEE C37.238-2011 or C37.238-2017) will not work with those network
switches.
•
Use the profiles Power (C37.238-2011), Power (C37.238-2017) or Power utility
(61850-9-3:2016) for power industry environments (OTMC 100p only).
b. Operation mode (General Settings pane): Always use the one step operation mode unless
there are devices in the network that do not correctly handle one step master clocks.
c. Domain number (Default Settings pane): All PTP devices that should synchronize to each
other must use the same domain number.
d. Transport (Port pane): Select the transport mechanism according to the needs of your
network. All PTP devices that should synchronize to each other must use the same transport
mechanism.
