Allocation Method Overview
This section provides an overview of allocation methods for performing
remote I/O communications from the master through the DeviceNet Commu-
nications Unit.
4-1-1
Overview
The DeviceNet Communications Unit can be used to allocate I/O memory in
the master to the following Temperature Controller parameters.
• Operation command/status parameters
• Monitor parameters
• Parameters that can be changed during operation
The DeviceNet Communications Unit can be used to select data from the
Temperature Controllers and DeviceNet Communications Unit and specify the
words to allocate to that data.
Data is automatically exchanged between the master and DeviceNet Commu-
nications Unit, allowing Temperature Controllers to be controlled and moni-
tored from the master without requiring special communications
programming.
Use either of the following two methods to allocate DeviceNet Communica-
tions Unit I/O in the master.
DeviceNet Master
