The PROFINET IO controller has the following system limits
Devices per ms Max. number of
devices
Max. number of
configurable con-
nections
1 128 20
0 0 24
O Output bytes per ms
n Number of devices
B Number output bytes per device
A Refresh time per device
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: for each 1 IO block > 256 byte is allowed.
– 4ms: for each 2 IO blocks > 256 byte are allowed.
– 8ms: for each 3 IO blocks > 256 byte are allowed.
– 16ms and greater: for each 6 IO blocks > 256 byte are
allowed.
