DANEO 400
Assigning IP addresses of the same subnet to more than one port of DANEO 400 has to
be done with care. Depending on the network topology, this may lead to a condition
where the control of DANEO 400 is interrupted.
When a port has an IP address assigned, it can be "pinged" (it will reply to an ICMP echo request).
This may as well be used for timing measurements.
Configuring the time synchronization
The device can use two possible time sources: a network PTP master clock for time synchronization
or the internal device clock. The PTP is designed for applications that require high time accuracies. If
you have a distributed measurement system with multiple devices you have to make sure that all
devices are time synchronized over PTP.
To configure the time synchronization:
1. In the Navigation pane, expand the device.
2. Click Time synchronization.
To use PTP as time source:
1. Make sure that there is a PTP master clock in the network.
2. Select PTP.
3. Choose the port that connects to the network to obtain the time synchronization.
Note: If the process ports (A and B) are in TAP mode and you choose any of these as the
PTP communication port, the PTP cannot determine the cable length. In this case, you must
enter the cable length (from the device port to the master clock) in Cable length.
4. Enter the VLAN ID and priority.
The device is not PTP time synchronized or is using the internal clock
The device is PTP time synchronized
The PTP details provide read-only information about the state of the current selected port and the
time synchronization clock.
To use the internal clock as time source:
1. Select Internal clock.
2. Click Apply PC time.
Configuring the inputs
In the Inputs section, you configure the physical connections of the device. Each input can be
configured either as voltage, current, or binary input. It is not possible to disable inputs.
To configure the inputs:
1. In the Navigation pane, expand the device.
2. Click Inputs.
3. In the Analog settings, choose the sampling frequency (10 kHz or 40 kHz) and enter the
nominal frequency (15 Hz...70 Hz).
