There are three kinds of HMI design that I can implement for you:

1. HMI application and peripheral devices have direct access via serial port or PCI card

2. HMI app. has communication to peripheral devices via local network

3. HMI app.  Has communication to peripheral devices via Internet/Intranet network.

The number of possible configurations may be increased due to various combinations. To achieve maximum HMI performance in reasonable price I prefer to create my own HMI and GUI applications, not using HMI systems such as WinCC, Cimplicity, Wonderware, etc.

In this case to control peripheral devices the HMI application constantly sends requests regarding the device status. If the system status is “OK”, operator may send commands to the device. In this situation screen is working in a normal mode. If status is “not OK” HMI generate alarm on a screen and switches to the abnormal mode. The system tracks all operator commands and statuses, keeping info in the log file and local DB. Reports are available by operator request

This case is similar to case 2 and from HMI perspective doesn’t have any difference

Flowchart: Magnetic Disk: DB Server

This case includes all functionality listed in case 1. The difference is the additional networking component and optional using of DB Server such as Sequel Server, Oracle and Inter Base.  To provide interface to Server DB I’m using ADO and ODBC technologies

Note: Please take to the consideration, that I don’t provide the Data Base development on a server side
