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.)

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.)
