Please consider the System SLIO power and clamp mod-
ules do not have any module ID. These may not be recog-
nized by the EtherNet/IP coupler and so are not listed and
considered during slot allocation.
Further within EtherNet/IP the slots are designated as
EtherNet/IP-Slot. The counting always begins with 1.
The EtherNet/IP coupler determines automatically the modules on the
System SLIO bus and generates from this the number of input and
output bytes. Information concerning the I/O allocation of a module
may be found in the corresponding manual. The position (offset) of
the input respectively output bytes within the input respectively output
data results from the order of the modules (EtherNet/IP-Slot 1 ... 64).
By means of the base address, which is to be preset in the EtherNet/
IP scanner for the bus coupler and the offset you may access the
input or output data of a module. During operation the EtherNet/IP
coupler cyclically reads the input data of the peripheral modules and
serves for the last state of these data for the EtherNet/IP scanner.
Output data, which the EtherNet/IP coupler has received from the
EtherNet/IP scanner, were directly transferred to the modules, as
soon as they were received.
