Table 5-5
Characteristic Explanation / Values
Size of the input area of the PROFINET IO device 512 bytes max.
Size of the output area of the PROFINET IO device 512 bytes max.
Size of the IO data area per submodule in a PROFINET IO device
S Inputs
S Outputs
240 bytes
240 bytes
Size of the consistency area for a submodule 240 bytes
Maximum number of submodules 32
Execution times of the FCs PNIO_SEND / PNIO_RECV
The calculation of the reaction times with PROFINET IO is determined by the
execution time of the function blocks required on the S7-300 CPU (PNIO_SEND,
PNIO_RECV).
