2.4 PickMaster time synchronization service
Time synchronization service
PickMaster Twin uses a time synchronization service to synchronize the time
between the robot controllers and the host PC running PickMaster. The
synchronization is performed over the same network used for communication
between PickMaster Runtime and the robot controllers.
Settings
The synchronization service is based on the precision time protocol (PTP), which
in turn implements the IEEE 1588 standard. This protocol uses multicast messages
over UDP/IP and requires that UDP port 319 and 320 are available (for both incoming
and outgoing traffic). It is therefore necessary that any firewall is not blocking these
ports. Please contact your system administrator to make sure that the proper
configurations are performed.
PTP was originally defined in the IEEE 1588-2002 standard, officially entitled
"Standard for a Precision Clock Synchronization Protocol for Networked
Measurement and Control Systems" and published in 2002. In 2008, IEEE 1588-2008
was released as a revised standard; also known as PTP Version 2, it improves
accuracy, precision and robustness but is not backward compatible with the original
2002 version.
The time synchronization service must be set to operate on the correct PC network
interface port, that is, the network port which communicates with the robot
controllers.

Note
To enable the time synchronization service, the user should select the local IP
address which is connected to the real controller during installing the PickMaster
Twin Client.
If the computer is not yet connected to a real controller, the IP address could
also be configured after the installation.
