Switch 10 in the RS-232 conguration group is used to set the Control Master
status. (DIP switch handles shown in black.)
In the VDC section, locate the 10‑position DIP switch in the RS‑232 area of
the rear panel. Switch #10 will set the 6416m to be the Control Master for the
Pro64 network when the switch is in the on (up) position (the up position is
shown in black in the diagram above).
Control Master Functions
This section describes the individual functions that the designated Control
Master device in a Pro64 network controls.
Enumeration
When the Control Master is powered on, its first job is to identify and count
all connected A‑Net modules in the network in a process called enumeration,
similar to a PC booting up and loading its operating system. The time for this
process will vary based upon the number of modules in a system.
Enumeration is an automated process performed by the command and
control portion of the A‑Net software. There are no user‑controllable
functions or settings.
