The data for the slaves 24B to 31B can not be displayed because of the limited
length of the process data channel. This data can only be accessed via the PCP-
channel.
AS-i allows the use of a bit position for both input and output purposes. As a rule,
AS-i slaves offer four inputs and outputs, each of which has its own bit position,
e.g.:
An AS-i slave uses its bits of the process data word as input or output data.
The order of the slaves on INTERBUS can be programmed in the AS-i/INTERBUS
gateway. It is not possible to access the data for slave 0, as this address is reser-
ved for configuration mode.
7.1.2 Control Word and Status Word
The INTERBUS master can use the control word to control the AS-i/INTERBUS
gateway. The status word indicates the current state of the AS-i/INTERBUS gate-
way to the INTERBUS master.
Control word and status word are transmitted with each cycle of INTERBUS, just
like the data on the process data channel.
