Set parameters 1401
RELAY OUTPUT 1 and 1402 RELAY OUTPUT 1 = 35 (COMM).
Then, for example using N2:
• To turn Relay 1 On: Force object B07 to On.
• To turn Relay 2 On: Force object B08 to On.
• To turn both Relay 1 and 2 On: Force objects B07 and B08 On.

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.)
