Communication Format
The communication format determines what type of data is transferred
between the module and its owner-controller. This feature also defines the
connection between the controller writing the configuration and the module
itself.
These communication formats are available for your module:
•
Data - Use this format for a controller that you want to own the module
and control its configuration data.
Only one controller can use the Data communications format when
connecting to a module.
•
Data - Output Window - Use this format for a controller that you want to
own the module and control its configuration data.
With this option, as opposed to the Data option, you can configure
specific output On/Off frequencies rather than use fixed
frequency limits.
This option is not available with all versions of the programming software.
•
Listen-only Data - Use this format for any controller that you want to
listen to the module but not own it.
Multiple controllers can use the Listen-only Data communication format
when connecting to the module. These controllers do not own the
module's configuration and lose their connection to the module if the
owner-controller loses its connection to the module.
When you select a Listen-only Communications Format, only the General
and Connection tabs appear when you view a module's properties in the
programming software.
This screen shows the choices available.
Once the module is created, the communication format cannot be
IMPORTANT
changed. The module must be deleted and recreated.
