3: Parameter Settings
These fields are used to display and set each parameter. The following table
shows the tag ITEMs used to set these parameters.
Numeral Display and Input objects are used to create these fields, and a ten-
key pad is displayed when a field is touched. The following table shows the
upper and lower limits of the setting ranges.
The following table shows the units that are displayed. These units are fixed.
The following values are used in communications between the PLC and NS-
series PT.
Data is written to the write address of each tag ITEM using a Before Writing
Numeral/String macro, as follows:
