APPENDIX A - HMI SERVER SYSTEM
15 May 13 A-1
Appendix A-HMIServerSystem
DESCRIPTION
This Appendix contains instructions for installing, connecting, and operating the HMI Server
System, which consists of an HMI Server and Router Switchgear Box (Figure A-1). The system
permits remote monitoring for the Derrick DE-7200 and DE-1000 Variable Frequency Drive (VFD)
centrifuges. By connecting a customer-supplied PC or laptop computer to the server, the operator
can monitor two to four centrifuges from a single location separate from the control cabinets. All
monitoring features that can be displayed on the control cabinet operator panel are made
available on the remote PC or laptop computer by means of a web-based interface. In addition,
the system can be re-configured by Derrick to permit remote operation.
