Data Addressing
When using the PROFINET protocol or the EtherNet/IP protocol with an EDS file, the input and output reg-
isters are named in the GSDML or EDS file. When using the EtherNet/IP protocol without an EDS file, both
the input and output registers start with address 0.
Addresses for the Modbus TCP protocol are given in
zero based
addressing in this manual. In this scheme, the
first register is given an address of zero. This is the actual addressing scheme used in the Modbus packets.
Input registers start at address 0. Output registers start at address 1024.
Output Data Format
Figure R2.1 below shows the format of the output data. The bottom eight bits of the first output word are used
to control the state of the eight relay outputs. A “0” in the bit location turns the output off. A “1” in the bit
locations turns the output on. Note that the state of these bits is ignored and the outputs are forced off if the
Output Mode momentary pushbutton is toggled to its Disabled state.
See bullet
of figure R1.1 on page 8 for location of the Output Mode momentary pushbutton and its LED.
Note that the Output Mode state is reported in the network input data.

nicate with the RBE2-8.
