Introduction

The Sm@rtAccess and Sm@rtService settings at the HMI device are defined in the "WinCCflexible Internet Settings" dialog box in the Control Panel.

Opening the Control Panel

You can open the control panel as follows (example):

• Select the "Settings > Control Panel" menu command in the Windows Start menu.

  In the case of the Windows CE HMI device, this can only be done during startup.

• During runtime, activate the operator control element associated with the "OpenControlPanel" system function.

  Note This enables you to modify settings on the HMI device during runtime.

The control panel may appear differently depending on the type of HMI device. The control panel of the MP 270 HMI device is illustrated here as an example:

Introduction

The Sm@rtService option of WinCC flexible provides the option to send messages automatically via e-mail.

The automatic e-mail delivery feature ensures that all people affected by the machine status (for example, shift engineer and sales manager) are informed in a timely manner.

Application example

Flow rate is one of the properties measured for process control of a cooling unit. Contamination in a feed line reduces the flow of coolant. When the flow rate drops below the configured limit value, the HMI device displays a warning. This warning is also dispatched as an e-mail to the assigned service technician.

The service technician then establishes a connection with the remote device and takes the appropriate actions.

Advantage: An alarm that reaches the service technician in a timely manner helps to minimize unplanned downtime.

Contents and triggers for e-mail delivery

The following events can trigger an e-mail to be sent:

• Alarm of a certain alarm class

• Event in which a standard function has been configured, such as a tag value change, etc.

Such an e-mail can have the following contents:

• Alarm text with process tags (maximum of 256 characters)

• Date/time

• E-mail address for replies

If you use e-mail gateways or SMS gateways, you receive access to standard networks, which requires external service providers. If configured accordingly, in critical situations the operator station sends an SMS to your mobile phone.

Enabling e-mail delivery and SMS

The HMI device can send e-mails to an SMTP server only. The server sends the e-mails to the addresses configured in the server.

Nothing else is required to send e-mails to addresses in the company network. However, an external service provider is required to access standard networks.

If an SMS communication is to be sent to service personnel, an SMS gateway is required as well.

Settings on the HMI device

The settings for e-mail delivery on the HMI device are carried out on the "E-mail" tab under "WinCC Internet Settings" on the control panel.

The "Sender" entry field is assigned the default value "Automation HMI device." This setting is useful if you want the receiver is to be able to determine the device where the e-mail originated, for example, "MP270 device on Production Line 2."

However, if the e-mail is sent via an authentication (in the case of a provider), you must enter a valid e-mail address for the "SMTP authentication," for example, "John.Doe@gmx.net".

i hope next time you try to use your own WCf Help...
