16-bit data
Information!
A-slaves map the data on channels 1 and 2.
B-slaves map the data on channels 3 and 4.
In addition to the access via the command interfaces, the 16-bit data for or by the
slaves with 16-bit value can by exchanged cyclically (profile 7.3., S-7.4, S-6.0, S-
7.5, S-7.A.8, S-7.A.9, S-7.A.A). Competing writing access attemps on 16-bit out-
put data will not be blocked by every other. If 16-bit output data for a particular sla-
ve are being transmitted both cyclically and acyclically with the command inter-
face, the acyclically transmitted values will be overwritten by the cyclically
transmitted values.
AS-i 16-bit data can be transmitted in a reserved data area. Therefore accessing
16-bit data is as easy as accessing digital data.
