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

Table 5-5

 

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

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

 

Execution time on the CPU

315−2DP

(6ES7 315−2EG10−0AB0)

per PNIO_SEND block call:

S

< 1 ms at 240 bytes

per PNIO_RECV block call:

S

< 1 ms at 240 bytes

Execution time on the CPU

317−2PN/DP

(6ES7 317−2EJ10−0AB0)

per PNIO_SEND block call:

S

< 0.8 ms at 240 bytes

per PNIO_RECV block call:

S

< 0.8 ms at 240 bytes
