Transfers between the
Computer and PT
Procedure
1. Connect the personal computer to the PLC by either a serial or network
connection.
2. Select Tool - Test.
3. Select Connect to PLC, specify the host name and host type for connect-
ing to the PLC, specify the communications method, and click the Start
Button.
4. The CX-Designer test function will start and the actual PLC will be con-
nected.
5. When the actual PLC user program is executed, the applicable host com-
munications addresses are changed according to the user program execu-
tion results, and this is reflected in the lamps on the screen and in the
numeric displays. Conversely, applicable host communications address
values are changed according to screen button operations and numeric in-
puts, and these are used as inputs for execution of the actual PLC user
program. This enables the simulation of screen operations in conjunction
with actual PLC user program execution.
When a project for which data transfer security has been set is stored in the
PT, a password is required to upload the project data from the PT. Data can-
not be uploaded from the PT unless the correct password is input, preventing
theft of data from the PT. A password is also required in order to download
data. This prevents data from being accidentally overwritten.
Select Connect to PLC,
specify the host name
and host type for
connecting to the PLC,
and specify the
communications
method.
Download
Upload
A password from the computer is required to
