SNTP Service SL Library Documentation ¶ Company : CODESYS Title : SNTP Service SL Version : 1.9.0.0 Categories : Application|Utils Namespace : SNTP Author : CODESYS Development GmbH Placeholder : SNTP_Service_SL Description [ 1 ] ¶ The SNTP Library contains function blocks for easy implementation of SNTP client and server components on a CODESYS control. The function block SNTPGetUTCTime can be used to request the UTC time of a SNTP/NTP server (SNTP V3, SNTP V4). The function block SNTPServer can be used to build a simple SNTP server. Function blocks of the SNTP library: Function block to request the time of a SNTP server: SNTPGetUTCTime (SNTP client). Function block to provide the local server time: SNTPServer (SNTP server) The package contains following components: Library SNTPService (Namespace: SNTP) Example project (SNTP client and server) Help file (chm) Product data sheet (English, German) The package SNTPService includes the library SNTPService and the example project SNTPExample . The application SNTPRequestExample shows the usage of the function block SNTPGetUTCTime . The application SNTPServerExample shows how to use the function block SNTPServer . Application SNTPRequestExample ¶ The application reads the current UTC time from a SNTP server and shows the result, the local time and the time difference in a visualization. Visualization of the application SNTPRequestExample Application SNTPServerExample ¶ The application SNTPServerExample starts a simple SNTP server on port 123.
