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.)
1. More than 3 relays requires the addition of a relay extension module.
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.)
