Description

Busy Timeout:

0 to 65535 This parameter specifies the number of milliseconds to wait for the

DF1 master port to become available. If the DF1 master port is

processing a command list request, the busy flag will be set. The

flag will remain busy until the communication transaction is

complete. If the port does not become available before the busy
timeout expires, the message will be aborted. If the master port

becomes available before this timeout expires, the request will be

routed to the master port.

ACK Timeout:

0 to 65535 This parameter specifies the number of milliseconds to wait for a

DLE-ACK character sequence after a response is issued.

Retry Count:

0 to 65535 This parameter specifies the number of attempts for each

response message. If a message fails, it will be retried up to the

count specified.

6.1.2 Switching between Pass-Through and Debug/Configuration

When the module’s program is initialized, it will be set with the Debug/

Configuration port in pass-through mode. A DF1 master device (that is,

PanelView or HMI) or programming device (that is, PC running RSLogix

software) can be connected to the Debug/Configuration port with the messages

routed through the port to Port 0 on the module. The module’s command polling

on Port 0 will be interrupted as messages from the pass-through port are

handled.
To switch the module to Debug/Configuration mode on the port, follow these

steps:
1 Connect the terminal device (personal computer running a terminal emulator)

to the Debug/Configuration port.

2 Start the terminal emulator software.
3 Change the baud rate to match the pass-through configuration.
4 Press and hold the [D] key on the keyboard until the following message

appears:
Change to 57.6 Kb Baud…

5 Change the baud rate on the terminal emulator software to 57.6 baud.
6 Press [?] key to display the module’s Debug/Configuration main menu.
The Debug/Configuration is now available. Refer to the ProLinx Reference Guide

for menu commands and other information).
To return the port to pass-through mode, press [*] (Shift-8) on the main menu.

When the message Exiting Debug Configuration Mode… appears, disconnect

the personal computer from the port and connect the DF1 master device to the

port.

Debug Port LED Indications
The following table shows the status indicated by the module’s LEDs. Note that

in the pass-through mode, the FLT and CFG LEDs act normally, indicating fault

and configuration problems.
