130 OPC UA Interface
timeout in 30 seconds. The session will be closed on the client. If the connection is accepted,
the client will be able to view and operate the VNC server.
For connectivity or application problems, the VNC server can optionally write its activities to
a log file. The VNC server must be configured to log its activities. An operator uses the Export
button at the bottom of the VNC Server Options panel to get a copy of the VNC log. You can
also use the Export button in the Diagnostic Export panel on the Main tab of the System
Setup screen.
To set the VNC configuration for logging, do the steps that follow:
1. On the Network tab of the System Setup, make sure the Enable VNC service option is
enabled (check mark in the checkbox).
2. Make sure the Log VNC session activity option is enabled (check mark in the
checkbox).
All VNC activity will be recorded to a log file.
To download the VNC log file, do the steps that follow:
1. On the Network tab of the System Setup, disable the Log VNC session activity option
(click to remove the check mark from the checkbox).
2. Insert a USB drive into any available USB port.
NOTE: The USB drive should have at least 5GB if free space. Log files from other sub-
systems are exported during this process.
3. Click the Export button at the bottom of the VNC Server Options panel.
NOTE: The Export button in the Diagnostic Export panel on the Main tab of the System
Setup screen can also be used.
4. Navigate to the location on the USB drive where you want the VNC log file saved.
5. Click the green check mark button.
The VNC log file will be written to the selected location and will have the name:
WinVNC.log.
If the VNC log file is unavailable when an export is started, there are two events that could
cause this:
• The log file was deleted immediately before the export was started.
• The “Log VNC session activity” option was not enabled during VNC activity.
If the VNC log file is not available when a download is done, a placeholder file will be created
with the same name (WinVNC.log) as the standard log. The contents of this placeholder file
will give the possible causes for the absence of the VNC session information.
10.2.7 OPC UA Interface
Husky gives you the option of using the industry standardized Open Platform
Communications – Unified Architecture (OPC UA) for safe, secure, and dependable data
exchange between machine to machine on the factory floor and/or machine to cloud in an
enterprise. The Husky OPC UA server supports the Euromap 82.2 standard for hot runner
devices. OPC UA relies on digital certificates to provide secure communication between a
client and a server so that the data is confidential and cannot be modified during
transmission.
