You select the PTP version you will use in the Time:PTP:Global dialog.

PTP Version 1, Global Settings

Tab. Function IEEE 1588/PTPv1

Parameters

Meaning

Possible values

Default setting

Sync Interval

Period for sending synchronization messages.
Entered in seconds.

In order for changes to take effect, click “Reinitialize”.

- sec-1
- sec-2
- sec-8
- sec-16
- sec-64

sec-2

Subdomain Name

Name of the PTP subdomain to which the local clock belongs.

In order for changes to take effect, click “Reinitialize”.

1 to 16 ASCII characters, hex value 0x21 (!) through 0x7e (~)

_DFLT

Preferred Master

Defines the local clock as the preferred master. If PTP does not find another preferred master, then the local clock is used as the grandmaster clock. If PTP finds other preferred masters, then PTP determines which of the preferred masters is used as the grandmaster clock.

true

false

false


Tab. Status IEEE 1588/PTPv1

Parameters

Meaning

Possible values

Default setting

Offset to Master [ns]

Deviation of the local clock from the reference clock in nanoseconds.

Delay to Master [ns]

Single signal runtime between the local device and reference clock in nanoseconds.

Grandmaster UUID

MAC address of the grandmaster clock (Unique Universal Identifier).

Parent UUID

MAC address of the master clock with which the local time is directly synchronized.

Clock Stratum

Qualification of the local clock.

Clock Identifier

Clock properties (e.g. accuracy, epoch, etc.).


Note: PTPv1 uses as the device UUID 48 bits which are identical to the MAC address of the particular device.

“Set”

Transfers the changes to the volatile memory (RAM) of the device. To permanently save the changes, open the Basic Settings:Load/Save dialog, select the location to save the configuration, and click “Save”.

“Reload”

Updates the fields with the values that are saved in the volatile memory (RAM) of the device.

“Reinitialize”

Restarts synchronization after changing the interval time and sets the Subdomain Name.

PTP Version 1, Port Settings

Tab. Port dialog version 1

Parameters

Meaning

Possible values

Default setting

Port

Port to which this entry applies.

The table remains empty if the device does not support the PTP mode selected

PTP enable

Port sends/receives PTP synchronization messages

on

on

Port blocks PTP synchronization messages.

off

PTP Burst enable

on: 2 to 8 synchronization runs take place during the synchronization interval. This enables faster synchronization with a correspondingly higher network load.

off: One synchronization run is performed in a synchronization interval.

on

off

off

PTP Status

Port is in the initialization phase.

initializing

Port is in the faulty mode. Error in the PTP protocol.

faulty

PTP function is switched off at this port.

disabled

Port has not received any information and is waiting for synchronization messages.

listening

Port is in PTP pre-master mode.

pre-master

Port is in PTP master mode.

master

Port is in PTP passive mode.

passive

Port is in PTP uncalibrated mode.

uncalibrated
