1. A motor control host, comprising:
- a plurality of ports;
a memory operable to store a configuration mask defining configuration access for each of the ports; and
a processing device operable to receive a configuration message over a particular one of the ports for changing a configuration parameter of the motor control host and accept or reject the configuration message based on the configuration access defined in the configuration mask for the particular port.

Abstract
A motor control system includes a first peripheral device and a motor control host. The first peripheral device is operable to generate a first configuration message. The motor control host includes a plurality of ports and the first peripheral device is coupled to a first one of the ports. The motor control host is operable to store a configuration mask defining access rights for each of the ports, receive the first configuration message over the first port, and accept or reject the first configuration message based on the configuration access defined in the configuration mask for the first port.

28. A motor control system, comprising:
-
a motor control host including a plurality of ports and being operable to store a security mask defining access rights for each of the ports; and
a least one peripheral device coupled to one of the ports, wherein the motor control host is operable to send a first message to the peripheral device including the security mask, and the peripheral device is operable to block subsequent messages conflicting with the access rights.
