Fieldbus adapter
Relay output control
Using the fieldbus for relay output control requires:
drive 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.
Analog output control
Using the fieldbus for analog output control (e.g. PID setpoint) requires:
drive parameter values set as defined below
fieldbus controller supplied analog value(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
