3 Functions of NB-Designer

NB-series Programmable Terminals NB-Designer Operation Manual(V106)
Note When the trigger sampling is used, if multiple samplings are performed at the same timing, only single value
might be acquired.
When such a state is assumed, place the Data Transmission component and others on the Common Sheet
and acquire the necessary data at local memory to perform the sampling for the local memory.
Pause-Clear The default Word Length is 2. “Pause” function stops temporarily the refresh of the graph
and the sampling operation will not be stopped temporarily. When “Pause-Clear” is checked
as shown blow, and the state of the specified bit address LB0 is set “ON”, the screen will
stop refreshing temporarily When the specified bit address LB0 is set “OFF”, the graph will
be refreshed and displayed.
“Clear” corresponds to the “address allocated temporarily to Pause + 1”. Specifying the
parameters as above, the bit address LB0 functions as “Pause” and the bit address LB1
functions as “Clear”. Displayed graph can be cleared only the changes occurred in LB1 state.
Scroll The default value is 3. For example, if the specified memory is LW0, LW0, LW1 and LW2 will
be the current browsing index value (the newest index value is 0 and the value is greater,
the data is older), the starting browsing index value and the maximum browsing index value
of Scroll Bar respectively. This option is valid only when “Multiple pages” is selected.
“Scroll” can be used to browse the multiple graph and can be in combination with the Scroll
Bar. For the specific using method of Scroll Bar, refer to 3-6-22 Scroll Bar (Page 3-164).
Time It is used to save the time when the latest sampling point is performed. “Time” option in
“Control memory Setting” is valid only when the “Save Time” is checked. The default
memory is LW and the Word Length is 12.
As shown as above, when the allocated address is specified to LW70, each data is stored
as below:
• The sampling time of the oldest data within the displayed page
Second: LW70, Minute: LW71, Hour: LW72, Day: LW73, Month: LW74, Year: LW75
• The sampling time of the newest data within the displayed page
Second: LW76, Minute: LW77, Hour: LW78, Day: LW79, Month: LW80, Year: LW81
