synchronized with a time server.

Fig. 37: Function block FB_SNTP
FUNCTION_BLOCK FB_SNTP
From firmware version BA:
If an empty string is entered in variable sSntpServer, the BC9000 will search for a time server. If no server is
found the process is terminated. If a time server is found, the IP address can be displayed via the
cCurrSntpServer variable. A rising edge of bStart activates the function block and starts the time server
query.
From firmware version BB:
If an IP address is entered the Bus Terminal Controller uses the SNTP protocol. If an empty string is
transferred, the time protocol (UDP port 37) is used.
