Network Computer Security - Honeywell Vertex M User Manual

Do not connect an external network to the Vertex M Ethernet hub. Use only the
external Ethernet connection (as shown in Figure 3-6) on the back of the data
acquisition computer. Connecting an external network to the hub will impair
monitoring capability.
When using an Ethernet output, the conduit must be connected to Earth ground.
l
The Vertex M comes with a Ferrite. Four wraps of the Ethernet cable is needed as close to the
l
Vertex M as possible.

3.7.3 Network Computer Security

The Vertex M relies on the HMI system of accounts and passwords to prevent unauthorized
tampering as described in "Security Access" on page 114 of this manual. Microsoft™ Windows™
provides its own system of accounts and passwords. However RSView32 requires that Windows
be run in an account with administrator privileges. Attempting to run the Vertex M HMI
application in a Windows™ account without administrator privileges will cause error messages
to be displayed. The Vertex M should be treated and secured as any other networked PC by
maintaining the appropriate virus protection. Contact local Honeywell field service
representative prior to installing Microsoft updates or Service Packs.
Use an external hardware firewall to isolate the monitor from malicious Ethernet traffic.
