Embedded fieldbus
Relay output control
Using the fieldbus for relay output control requires:
Drive parameter values set as defined below.
Fieldbus controller supplied reference word(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.
For example: To control relays 1 and 2 using serial communication:
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.
Note: Relay status feedback occurs without configuration as defined below.
