Cyclic Structure: (Time stamp) (KODO) (CMDD) (BUFC)
Acyclic Structure: (Time stamp) (KODO) (CMDD) (OBJ) (DATA)
KODO – Kind of Data Object:
PDO = Process Data Objects (cyclic communication)
SDO = Service Data Objects (acyclic communication)
CMDD – Command Direction:
get = Received Data over Interface
set = Transmitted Data over Interface
BUFC – Buffer Content:
Ethercat: Order depends on the current PDO-Mapping
DeviceNet: Order depends on the current used assembly
CC-Link: Order depends on Profile 2
Pofibus: Order depends on the current used Profile
OBJ - Object:
The Parameter object where data is received or transmitted to it
DATA:
In case CMDD is get.
→ All data with data type float are send in IEEE-754 Standard
→ PDO cyclic data are traced in case of buffer content has changed.
