Configuring the Modules
This chapter shows you how to configure the 1771-TCM module.
This includes:
•
configuration selections
•
uploading and downloading information
•
accessing the Module Configuration screen
•
downloading configuration values
•
uploading configuration values
•
module description
•
copying configuration values from one module to another
•
copying configuration values from one module into a new module
•
moving a module from one project to another
On the module configuration screen, you are given several
configuration selections to establish. However, your selections do
not control the PLC data table values in real time. These selections
do not take effect until you download the selection to the PLC data
table interface area.
The configuration software can write (download) configuration
information directly to the PLC data table in online mode, or it can
write it to a disk file in off-line mode. Similarly, the configuration
software can also read configuration information from the PLC
processor or from a file.
In order to use online mode, you must have a DH+ or serial
connection with the PLC processor, and INTERCHANGE must be
properly configured and running. When you write configuration data
to a file, it is stored as part of the project file. It is a good idea to
always download to both the file and to the PLC processor. This
way, the file retains a copy of all of the configuration data; you can
then use this copy to restore the configuration data to the PLC
processor if that information is ever lost or damaged.
Downloading to the file alone lets you perform configuration
functions while you are disconnected from the PLC processor. Once
you are attached to the PLC processor, you can transfer information
from the file to the processor by first uploading from the file, and
then downloading to the processor. When you are simply testing
changes, you may want to download only to the PLC processor so
that the file retains your un-altered settings. Once you are satisfied
with those changes, you can download to the file to save them.
