CP as PROFINET IO device

The CP supports the following maximum configuration as a PROFINET IO device:

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	240 bytes
S	Outputs	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).

Table 5-6

Component	Explanation / Values
Execution time on the CPU	per PNIO_SEND block call:	per PNIO_RECV block call:
315−2DP	S < 1 ms at 240 bytes	S < 1 ms at 240 bytes
(6ES7 315−2EG10−0AB0)
Execution time on the CPU	per PNIO_SEND block call:	per PNIO_RECV block call:
317−2PN/DP	S < 0.8 ms at 240 bytes	S < 0.8 ms at 240 bytes
(6ES7 317−2EJ10−0AB0)
