4-1 Overview
I/O memory in the master can be allocated to data from the E5AR/ER-DRT
Digital Controller, such as data from the Digital Controller’s variable area,
merely by specifying what Controller data is to be transferred to where.
Data is automatically exchanged between the master and Digital Controller,
allowing the Digital Controller to be controlled and monitored from the master
without requiring special communications programming.
4-2 I/O Allocation
The Configurator can be used to select any data from the list of allocation
parameters for the Digital Controller and then allocate the data in a user-set
destination. Data is selected by specifying the allocation number assigned to
the desired parameter.
