AS-i 3.0 EtherNet/IP+Modbus TCP Gateway
EtherNet/IP interface
16-bit data
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
slave are being transmitted both cyclically and acyclically with the command inter-
face, the acyclically transmitted values will be overwritten by the cyclically trans-
mitted values.
Data of all channels of a slave can be transmitted in a reserved data area. There-
fore accessing 16-bit data is as easy as accessing digital data.
