(1) Host controlling means that the module is receiving level data for output from its host module.
(2) Output is being held due to bus halt. Halt is where the expansion module is advised to extend its link timeout temporarily.

4...20 mA Output Status Indicators

Each status indicator represents the state of that particular channel or output.
Normal expected status indicator states for a healthy system are all solid green.
For each output (channel), if the output is not enabled, the associated status
indicator is off.
If enabled:
• Blue if the output is inhibited or the link is halted
• Red when the link fault output value is imposed by the expansion
module
• In either case, the output is likely being held static (same value
maintained)
Otherwise, the output status indicator is green.
The color is always solid, except all enabled channels flash the active color
during a link fault.
