5.2.6 “RTU IO Mapping” Interface
Clicking on “ IO Mapping ” button on the main interface, the “ RTU IO Mapping ” interface appears
right away, where the inputs and outputs of digital modules and special modules are listed.
See details in section 5.3.
Explanation of parameters in the RTU IO Mapping interface:
Item Description
Input IO Data
Mapping:
The data that RTU-CN01 transmits to the master
Output IO Data
Mapping:
The data that the master transmits to RTU-CN01
No.
Module name and the position of the special module on the right side of
RTU-CN01, including the special module name and its position number, the
status word and control word as well as digital module input type and output
type.
Description The name of a mapping parameter
Word Data length of a mapping parameter, unit: word

5.3.1 IO Data Mapping

If the control word and status word of RTU-CN01 are excluded in IO data, only special modules and
digital modules are configured. E.g. in the following figure only four channels of outputs for DVP04DA-S
and four channels of inputs for DVP04AD-S and 8 digital inputs and 8 digital outputs are configured.
