The recipient checks and fetches its s from the Microsoft Exchange server with the POP3-protocol Ethernet-Controller PC Microsoft Outlook 98 PC Microsoft Exchange Server 3 Reference Material The connection was tested under the following prerequisites. Assigned hardware components: WAGO Controller Standard PC Assigned software components: WAGO I/O Pro 32 V2.1SP10+ SMTP_MAIL.lib Version 1.1 Microsoft Outlook 98, Microsoft Exchange Server

7 Solution 7 4 Solution 4.1 Integration into a WAGO I/O PRO program A mail client is implemented on the part of the WAGO controller. For this purpose a functional module is made available in the library MAIL_01.lib. The call of this module can be seen in the following picture. A detailed description of the parameters is to be found in chapter 4.2. In this example mail is sent by "SYSTEM" to "IT_Service@domain.com". In the reference text line of Outlook appears the following: "ALARM: Fire early recognition system computer centre ". The actual message reads: "Fire early recognition system responded". The parameter sip indicates the IP address of the Microsoft Exchange server.
