Status Words
The status words show the status of the SmartSlice I/O Units in the Smart-
Slice I/O Terminal, the connection status with the CompoNet Master Unit, and
the participation status.
There are two type of status: Status of the CompoNet Communications Unit
and the participation status of the SmartSlice I/O Units. There are different
words for each of these.
Two-point Analog Input Unit (GRT1-AD2): 2 words (4 bytes)

7 + Communications
Unit status = 30 bytes in Input Area
Analog Output Unit (GRT1-DA2C): 2 words (4 bytes)
