6.12 Configuring drive-related I/Os (with symbolic assignment) 
  SIMOTION D4x5-2 
256  Commissioning and Hardware Installation Manual, 02/2012 
Procedure 
The configuration of the I/Os is divided into two basic steps: 
1.  Configuration of the I/O terminals (Page 257). The functionality of an I/O channel is 
config
ured (e.g. configuration of a DI/DO as digital output). 
2.  Configuration of the technology objec
ts and I/O variables. (Page 262)  
The access of technology objects and I/O variables to I/Os is configured. 
The configuration is performed symbolically, whereby only "function-compatible" I/O 
channels are offered for selection.  
Example:  
For the TO measuringInput, only symbolic assignments of the type MI (measuring input) 
are offered for selection. 
The required message frames and the interconnection are then set automatically by the 
engineering system.
