## Abstract

A wireless user interface is operable to interface with an industrial control system including a device operable to store a first password and a wireless interface module operable to store a second password. The wireless user interface includes a processing unit operable to prompt a user for the first and second passwords, connect to the wireless interface module using the second password, and establish a first connection through the wireless interface module to access the device using the second password.

## Claims

### Claim 1

An industrial control system, comprising:
a motor drive having a plurality of interface ports and being operable to store a first password, the motor drive including a control application, the control application including instructions for controlling power control electronics to apply a voltage to a motor, the interface ports including at least one of serial ports, human-machine interface (HMI) ports, and network interfaces;
a wireless interface module coupled to a first interface port of the motor drive and operable to store a second password; and
a wireless user interface operable to prompt a user for the first and second passwords, connect to the wireless interface module using the second password, establish a first connection through the wireless interface module to access the motor drive using the second password, retrieve a status of the motor drive using the wireless interface module and transmit control instructions to the wireless interface module in response to a user input, the control instructions including at least one of start instructions, stop instructions, jog instructions, forward instructions, and reverse instructions, the wireless user interface establishing an exclusive connection to the wireless interface module and being operable to communicate with the wireless interface module using a first protocol and to communicate with the motor drive using a second protocol different from the first protocol, wherein messages formatted using the second protocol are encapsulated by the first protocol for communication between the wireless user interface and the wireless interface module.

### Claim 2 (depends on 1)

The system of claim 1, wherein the motor drive is operable to store a password required flag and the wireless user interface is operable to prompt the user for the first password responsive to the password required flag being set.

### Claim 3 (depends on 2)

The system of claim 2, wherein, responsive to the password required flag being cleared, the wireless user interface is operable to not prompt the user for the first password, and the motor drive is operable to allow the wireless user interface to establish the first connection without the first password.

### Claim 4 (depends on 1)

The system of claim 1, further comprising at least one peripheral associated with the motor drive, wherein the wireless user interface operable to establish a second connection through the wireless interface module to access the peripheral.

### Claim 5 (depends on 4)

The system of claim 4, wherein the wireless user interface is operable to communicate with the wireless interface module using a first protocol and to communicate with the peripheral using a second protocol different from the first protocol, and wherein messages formatted using the second protocol are encapsulated by the first protocol for communication between the wireless user interface and the wireless interface module.

### Claim 6 (depends on 4)

The system of claim 4, wherein the peripheral is operable to store a password required flag and a third password, and the wireless user interface is operable to prompt the user for the third password responsive to the password required flag being set and to establish the second connection using the third password.

### Claim 7 (depends on 1)

The system of claim 1, further comprising:
a communication network;
a communication module coupled to a second interface port of the motor drive and operable to communicate over the communication network;
a device coupled to the communication network,
wherein the wireless user interface is operable to establish a second connection through the wireless interface module and the communication module to access the device.

### Claim 8 (depends on 7)

The system of claim 7, wherein the wireless user interface is operable to communicate with the wireless interface module using a first protocol and to communicate with the device using a second protocol different from the first protocol, and wherein messages formatted using the second protocol are encapsulated by the first protocol for communication between the wireless user interface and the wireless interface module.

### Claim 9 (depends on 7)

The system of claim 7, wherein the device is operable to store a password required flag and a third password, and the wireless user interface is operable to prompt the user for the third password responsive to the password required flag being set and to establish the second connection using the third password.

### Claim 10

A wireless user interface operable to interface with an industrial control system including a device operable to store a first password and a wireless interface module operable to store a second password, comprising:
a processing unit operable to prompt a user for the first and second passwords, connect to the wireless interface module using the second password, establish a first connection through the wireless interface module to access the device using the second password, and transmit control instructions to the wireless interface module in response to a user input, the processing unit being operable to communicate with the wireless interface module using a first protocol and to communicate with the device using a second protocol different from the first protocol, wherein messages formatted using the second protocol are encapsulated by the first protocol for communication between the wireless user interface and the wireless interface module.

### Claim 11 (depends on 10)

The interface of claim 10, wherein the device is operable to store a password required flag and the processing unit is operable to prompt the user for the first password responsive to the password required flag being set.

### Claim 12 (depends on 11)

The interface of claim 11, wherein, responsive to the password required flag being cleared, the processing unit is operable to not prompt the user for the first password, and the device is operable to allow the processing unit to establish the first connection without the first password.

### Claim 13 (depends on 10)

The interface of claim 10, further comprising at least one peripheral associated with the processing unit, wherein the processing unit is operable to establish a second connection through the wireless interface module to access the peripheral.

### Claim 14 (depends on 13)

The interface of claim 13, wherein the processing unit is operable to communicate with the wireless interface module using a first protocol and to communicate with the peripheral using a second protocol different from the first protocol, and wherein messages formatted using the second protocol are encapsulated by the first protocol for communication between the processing unit and the wireless interface module.

### Claim 15 (depends on 13)

The interface of claim 13, wherein the peripheral is operable to store a password required flag and a third password, and the processing unit is operable to prompt the user for the third password responsive to the password required flag being set and to establish the second connection using the third password.

### Claim 16 (depends on 10)

The interface of claim 10, further comprising:
