Ready Mode
All channels are off when in the Ready mode, the Ready indicator is GREEN and
the Run indicator is RED while the channel indicators are OFF. When an
application is started, the module transitions to the Run mode.
When a module loses communication with the processor, then it transitions back
to the Shutdown mode.
Run Mode
In the Run mode, all channels regulate the output current to the commanded
value for each individual channel. The Ready and Run indicators are GREEN.
You must make sure that all the user-required values have been set (by using
RSLogix 5000 or Logix Designer software) before transitioning the module to
Run mode.
If, for any reason, a module does not receive commanded values, then the module
transitions to the Shutdown mode.
Shutdown States
You can configure the channel shutdown states to do one of the following:
• Turn-off/de-energize the channel
• Hold last state
• Regulate the output to a specified value
The shutdown state shall default to turn-off/de-energize.
