Fieldbus adapter
Bypass relay output control
Using the fieldbus for relay output control requires:
• Bypass parameter values set as defined below.
• Fieldbus controller supplied, binary coded, relay command(s) in the appropriate
location. (The location is defined by the Protocol Reference, which is protocol
dependent.)
Note:
Relay status feedback occurs without configuration as defined below.
Communication fault
When using fieldbus control, specify the bypass action if communication is lost.
