Special Operation
Command Word
The Special Operation word format is shown in the figure below. It contains
the Command Code, and the Channel Number. The Command Code speci-
fies the action to be performed, the Channel Number specifies channel to
which the action will apply. Both the Command Code and Channel Number
coding are listed in the table below.
Since the Command Word will be part of the cyclic data exchange, a mecha-
nism in the PRT1-SCU11 is used to send this word to the targeted device only
when needed. The PRT1-SCU11 will transfer the command word to the target
device up on a change of one or more of the bits in the contents of the Com-
mand Word.
Response Word
Once the command has been sent, the response from the device is placed in
the PROFIBUS input Operation Execute word. The format of the response is
shown in the figure below. the Operation Execute word contains the Com-
mand Code, the Channel Number as well as an Error Code bit. If the Error bit
(bit 4) is set, an error has occurred in the communication with the targeted
device.
