E84AYCER communication manual (PROFINET)
Technical data
Protocol data
Example
Which type of protective insulation is implemented between the bus terminal of the
device module in slot MCI and mains terminal X100?
The separate potential area with the better protective insulation is decisive.
– The separate potential area of the device module bus terminal is "functionally
insulated".
– The separate potential area of the mains terminal has a "reinforced insulation".
Result: The insulation between mains terminal X100 and the bus terminal is of the
"reinforced insulation" type.
4.3 Protocol data
4.4 Communication time
The communication time is the time between the start of a request and the arrival of the
corresponding response.
The communication times in the PROFINET network depend on the ...
Processing time inside the controller;
Telegram runtime (baud rate / telegram length);
Nesting depth of the network.
Processing time inside the controller
There are no interdependencies between parameter data and process data.
Field Values
Process data words (PCD) Max. 16 process data words (max. 32 bytes)
Acyclic parameter data channel Limited by the PROFINET frame size
Data Processing time
Process data Approx. 2 ms
