Section 7: Modbus I/O List
The following paragraph describes the I/O composition of the Modbus interface implemented in the
XTE3000 Modbus RTU module. The XTE3000 Modbus RTU module concentrates all the available data
in the Holding Register Data Area, but to grant the backward compatibility with the ICON2000v4,
it maintains also the former data structure.
The Modus interface is divided in four areas and each area is accessible via the specific Modbus
Function Code as described in Section 8.
7.1

Discrete Inputs

In the Discrete Input Data Area, the XTE3000 Modbus RTU module implements the same 32 discrete
inputs available on ICON2000v4.
Status of discrete inputs is indicated as 1 = ON and 0 = OFF.
The following table shows the discrete inputs implemented in the XTE3000 Modbus RTU module:
