The PROFINET IO controller has the following system limits:
n
Max. Number output bytes per ms: 800
n
Max. Number output bytes per device: 256
I
Input bytes per ms
n
Number of devices
C Number input bytes per device
A Refresh time per device
The PROFINET IO controller has the following system limits:
n
Max. number input bytes per ms: 800
n
Max. number input bytes per device: 256
With the following conditions there is the possibility to increase the number of bytes up to
512 input and 512 output bytes per device, with it your project still runs.
n
There are max. 13 PROFINET IO devices configured.
n
For each PROFINET IO device, depending on the time of
refresh time per device
, the
following conditions must be met:
–
1ms: There are no IO blocks > 256 bytes allowed.
–
2ms: 1 IO block > 256 byte is allowed.
–
4ms: 2 IO blocks > 256 byte are allowed.
–
8ms: 3 IO blocks > 256 byte are allowed.
–
16ms and greater: 6 IO blocks > 256 byte are allowed.
