Set Data logger mode to Automatic.
Note: The settings depend on the configuration required by a device interface.
Panel bus settings
The figure below shows the Interface settings dialog box of the Panel bus connection.
•
Cable check is a drop-down list for enabling or disabling the function.
•
When the cable check function is enabled, the NETA-21 tries to identify the
connected cable (by testing the input voltage from the drive control board). The
panel bus connection scanning runs in the background only if the cable (input
voltage) is detected on the PNL1 or PNL2 port.
•
When the cable check function is disabled, panel ports are scanned continuously
even if the cable is not connected. If the input voltage is not available from the
panel bus, this option can be used for detecting panel bus devices. When the
cable check function is disabled, there is extra background CPU load in the NETA-
21. The PNL1/PNL2 LEDs are red if no panel bus device cannot be detected. See
LED indications of the NETA-21 .
•
Ethernet GW is a drop-down list for enabling or disabling the gateway mode. By
default, Ethernet gateway is disabled. There are four different options to enable this
feature:
•
Enable - Enables the Ethernet gateway permanently. This can weaken security
and is not recommended.
•
Enable while in use - Keeps the gateway open, as long as data is flowing through.
Gateway is disabled automatically after 10 seconds of inactivity.
•
Enable 1 hour - Keeps the gateway open for 1 hour from the time it is enabled,
regardless of inactivity.
•
Enable 24 hours - Keeps the gateway open for 1 day from the time it is enabled,
regardless of inactivity.
Note: For security reasons, PC tool Ethernet gateway connections for Panel Bus must
be used only inside a trusted network.
•
Time synchronization is a drop-down list for enabling or disabling the function. When
enabled, NETA-21 will act as a clock master for the drives connected via this interface.

Connection speed (pnl2) shows the speed for the active connection.
