WARNING
UNEXPECTED APPLICATION BEHAVIOR-VALIDITY OF COMMON WORDS
The update bit switches to 1 at the beginning of the PLC cycle if it receives common words from the corresponding station. At the end of the cycle the update bits automatically return to 0.
Consequently, common words can only be considered valid if the update bit of the corresponding station is set to 1.
After power up, common words are set to value 0.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
The table below shows the implicit exchange objects of the IODDT of type T_COM_ETY_1X0 which applies to the two modules TSX ETY110/120.
