Procedure for Converting Data from Version 1.3@ to a Higher Version
Handling Function Blocks with Open I/O Connections
Note Data cannot be converted to a lower version, such as from unit version 2.0 to
unit version 1.0.
Data created using Network Configurator version 1.3@ can be used with a
higher version without any problems if converted as outlined below. Data cre-
ated with higher versions cannot be used with lower versions; the data upload
from the device will fail when loading the project file.
Version 1.5@ and higher have improved safety check functions, so
version programs from lower versions will need to be checked for
safety. Use the following procedure to check programs.
a. Click the Logic Tab on the Edit Device Parameters Window of the
NE1A-series Controller and click the Edit Button to start the Logic Ed-
itor.
b. Select Edit - Find Function Blocks with Open Connections to
check that all function block I/O have connections.
c. Select File - Apply to save the logic program then exit the editing of
the logic program.
d. Return to the NE1A-series Controller's Edit Device Parameters Win-
dow and click the OK Button.
Note Data created using version 1.3@ cannot be monitored online.
Always convert the data to version 1.5@ and download it before
monitoring online.
Function block outputs with open connections in version 1.3@ data could still
be downloaded (see following diagram).
Download cannot be executed with version 1.5@ or higher, however, if there
are outputs with open connections (to improve the program validity).
For this reason, data created using version 1.3@ cannot be downloaded as is
for use with version 1.5@ or higher. If open connections exist in version 1.3@
data, use the Search Open Connection function and use the Set Output Point
Tab Page in the Safety Gate Monitoring Window for the function block with
open connections to disable the outputs or connect the open connections to
output I/O tags.
Note Versions 1.5@ and higher have functions for creating text boxes on program
screens and changing the I/O tag color. The text box and I/O color data is not
Open connection
