3.1.5 Commissioning
Commissioning is the process of taking the S70 Servo from the on-line state to establishing a
dedicated connection with a master on the network. The S70 Servo supports a Polled network
connection and an Explicit message connection. These connections are supported
simultaneously but only one connection of each type is supported at a time.
When the S70 Servo transitions from the On-line state to the Commissioned state, the Network
LED (Section 3.1.4) will change from flashing green to a solid green. When the Master / Slave
relationship is released, the Network Led will return to a flashing green.
As an example, if the Mac Id of the S70 Servo is added to the scan list of a process controller,
the process controller will establish a Polled Message connection with the S70 and will transition
the S70 Servo to the commissioned state. Once the S70 Servo is commissioned, the process
