Configuring the Address Source
You can choose between Application and Manual for the Address Source.
Application—If you choose Application, the terminal uses the current
application file’s Pass-Through Address Source.
If the application file contains a Pass-Through configuration, its values
are displayed in the Manual Address Source area.
If the application file doesn’t contain a Pass-Through configuration or
there is no application present in the terminal, you will see asterisks
displayed in the Manual Address Source area. Without valid parameters
in the Address Source, the Pass-Through transfer fails.
Manual—If you want to change any of the Manual Address Source
entries, you must change the Address Source to Manual.
When you choose Manual, the following message pops up:
Choosing Manual
Address Source will
disable the Terminal’s current application
file. Select Application
to enable.
This message remains on your screen until you toggle the Address
Source to Application.
If you choose Manual when the current application file has no
Pass-Through configuration and a manual address has not been
configured and saved previously, the asterisks will be replaced by these
defaults:
Parameters Defaults
PLC Type
PLC-5/25
Baud Rate 57.6K

Last Chassis Yes
Module Group 0
High/Low Byte Low
Note Once a valid application file exists in the terminal, you can
download to the same address. Or you can configure the Pass-Through
address manually at the terminal to match the application file’s
Pass-Through address.
