FROM/TO Execution Time
The PROFIBUS cycle time and FROM/TO instruction operates asynchronously. If data is written to the 32DP
in the PROFIBUS cycle time, this data will move to the system area on the next PROFIBUS cycle time.
Reference
The FROM/TO Execution Time varies as follows, depending on the data amount to be transferred.
