6.3.2 Cyclic data traffic
In cyclic data traffic, the COM190 communication module exchanges the configured user
data with the controller in each set cycle.
Cyclic data exchange is especially suitable for transferring information that is required
continuously and quickly. The COM190 communication module fits into the PROFINET Real-
Time (RT) time control.
• The PROFINET IO controller specifies the parameterizable update time.
• The maximum quantity structure of the cyclic data is 244 bytes of input data and 2 bytes
of output data.
• The COM190 communication module supports update times of 1 to 512 ms.
