elements.

Online Operations

You can perform the following functions when you work on line:

• Communicate with devices

• View the status of I/O with online animation

• Change logic

• Change the value of timers and counters

• Enable and disable logic

• Verify logic

• Compare logic

• Upload and download logic

• Force

• Clear latched hardware faults

Communication with Devices

The old DeviceLogix Ladder Editor communicates with the devices to
accomplish the following:

• Determine device type

• Get communication parameters

• Set communication parameters

• Download configuration to the device

• Upload configuration from the device

• Modify function block parameters during animation (for

example, Preset value and Accumulated counts for counters or
Preset time and Elapsed time for timers)

• Force I/O values

• Start or Stop local logic (toggle Logic Enabled)

• Display device faults during animation

• Clear I/O faults

• Reset the device

Note that all communication between the old DeviceLogix Ladder
Editor and the device is done using explicit messaging connections.
