3. Edit the parameters, and then click the OK Button. The parameter will be
changed, and then the filter will be updated.
Note (1) Parameter changes are performed for the file.
If a user-defined function block is edited, the changes will be applied to
all instances of that user-defined function block.
(2) Parameters that change the number of inputs or outputs of a function
block cannot be edited (e.g., setting the number of I/O, setting to use or
not use Fault Preset, and changing from Dual Channel to Single Chan-
nel).
Precautions When Using User-defined Function Blocks
User-defined function blocks cannot be edited once they have been allocated
in a program. Editing must be performed while the function block is not being
used in a program. To check the contents after allocation, right-click the user-
defined function block in the program and select
Monitoring or Edit (see next
diagram).
Example Screen Display When User-defined Function Block Is Right-clicked
and
Monitoring Is Selected:
Note The values for I/O tags in function blocks and the status of signal connections
with function blocks can be monitored online if the Network Configurator is
online and the NE1A-series Controller is in RUN mode.
The following diagram shows how I/O that are not used in user-defined func-
tion blocks are displayed on screen. Used outputs are indicated in red and
unused outputs are indicated in gray. Unused I/O connections cannot be con-
nected.
