How do you use a GPS receiver to determine the coordinates and synchronize the system time of the S7-1200, S7-1500 and ET 200SP CPU?

  • Entry
  • Associated product(s)
You receive in this entry a library for STEP 7 (TIA Portal) for receiving GPS data via the RS232 interface. A sample project shows you how to receive GPS data with the SIMATIC controllers S7-1200, S7-1500 and ET 200SP CPU.

Description
The SIMATIC controllers S7-1200, S7-1500 and ET 200SP can process standard GPS frames of the RMC data type according to the NMEA-0183 standard. A GPS receiver captures the GPS frames via the RS232 interface of the communication modules CM1241 RS232, CM PtP RS232 and CM PtP.

The function blocks in the attached library provide the degrees of longitude and latitude of your current position. In addition, the current UTC time and date in the "DTL" data type format are output and the system time of the CPU is synchronized.

Download Documentation
The PDF document gives a detailed description for STEP 7 (TIA Portal) V15 for GPS reception with S7-1200, S7-1500 and ET 200SP CPU.

Download Project
Unpack the Zip file in a separate directory on your hard disk. Then you can open and edit the project with STEP 7 (TIA Portal).

Download Library
Unpack the Zip file in a separate directory on your hard disk. Then you can open and edit the library with STEP 7 (TIA Portal).

Note
You can only open and edit the library in STEP 7 (TIA Portal). Further information about opening libraries is available in Entry ID: 37364723.
