Embedded fieldbus
Bypass relay output control
Using the fieldbus for relay output control requires:
• Bypass 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.)
For example: To control relays 1 and 2 using serial communication:
From the bypass keypad, set parameters 1401
RELAY OUTPUT 1 and 1402 RELAY
OUTPUT 2 = 16 (COMM CTRL).
Then, for example using N2:
• To turn Relay 1 On: Force object BO5 to On.
• To turn Relay 2 On: Force object BO6 to On.
• To turn both Relay 1 and 2 On: Force objects BO5 and BO6 On.
Note: Relay status feedback occurs without configuraton as defined below
.
