Description
Local
• • • • • • • • •
In Local mode, the AOP mounts directly onto one SED2 VFD
and then scans its RS-232 and RS-485 ports to establish
communications with the first port that answers. You can
control the SED2 VFD by accessing all normal SED2 and AOP
internal parameters. Local mode is the default of the AOP on
initial power-up or after a reset.
Master
• • • • • • • • •
In Master mode, the AOP can control up to 31 SED2 VFDs
which connect in a multi-drop arrangement. An operator can
control each SED2 VFD by accessing all normal SED2 and
AOP internal parameters. In Master mode, the network
controls the SED2 VFDs either individually or by broadcast
operation. A broadcast operation can simultaneously start or
stop all networked SED2 VFDs.
Internal
• • • • • • •
In the Internal mode, you can access the stored parameter
sets in an AOP. You can not access any parameter sets stored
in the SED2 VFDs.
In the Internal mode, the main menu includes an Engineering
item. This menu item allows you to view a USS message log of
the last 1k bytes of messages between the AOP and the
connected SED2 VFDs.
Slave • In Slave mode, the AOP communicates with a PC using the
AOP Desk Mounting Kit. In this configuration, the AOP acts as
a slave to the PC. At the PC, you can upload and access
parameter sets or the AOP internal parameter set as a USS
address, numbered 1 through 10.
PC Mode • In PC mode, the AOP is used with a Panel Mounting Kit to
control a network or SED2 VFDs. In this configuration, the
AOP acts as an RS-232/RS-485 converter. In PC mode, you
can modify only the communications baud rate function.
