Control Master
In every Pro64 network, one device will always be designated as the Control
Master, the device that manages all A‑Net resources for the network. The
Control Master can be any I/O module in the network, and can be assigned or
changed by the user as needed. Only one device can be assigned as Control
Master in a Pro64 network at a time; an A‑Net Pro64 network cannot function
without a Control Master.
The functions of the Control Master include:
System resource and information management
•

•
active channels (Slots) in Auto Mode

The Control Master status is identified with a red LED on the front panel of
the device currently assigned as the Control Master. Depending on the type
of device (rack‑mounted I/O module or console interface card), the method
used for designating Control Master status may be different.
The Control Master LED is labeled CTL on the 6416Y2 card.
