  • Entry
  • Associated product(s)

With the S7 program available for download in this FAQ document you can acquire the UTC time and date information from a GPS signal. This is effected with the help of a GPS mouse which receives the GPS signal in the form of an NMEA protocol and transmits it to a
SIMATIC S7-300/400 CPU for further processing.

The current time and date information is used to set the CPU module clock.
