TPS-1 IO Data Size Limitations

Last Updated:06/01/2017


Is it possible for the TPS-1 to support 1440 bytes of IO data? If so, how should I do it? In hardware or software?


The TPS-1 cannot support 1440 bytes of IO data, as the structure of the IO RAM limits the IO data size. However, typical PROFINET frames have much smaller amounts of IO-data. TCP/IP frames are tunneled by TPS-1 to the host CPU, therefore TCP/IP frames can have up to 1440 bytes.
