OMRON-PLC programmable Terminal (PT) data

NT31/NT31C digital memory table stored value can be displayed (decimal or hexadecimal). By changing the digital data can be stored in the memory table to change the displayed number. Displays the decimal number, displayed value the integer part and the fractional part of the number should be set in advance.
 
(1) display
 
The string is stored in the string that is displayed in the memory table. By changing the string data stored in the memory table and change the string that is displayed.
 
(2) digital inputs
 
Touch switches can be used in the PT, enter a numeric value. Enter values in the table can be stored in a digital memory and to notify the host computer.

(4) the dial switch
 
Through the corresponding touch switch (+,-) to increase or decrease each digit and enter a numeric value. Input values can be stored in a digital memory table and inform PC.
 
(5) graphics
 
These graphic displays are based on numeric values stored in the memory table changes. Bar chart, line chart, chart three shapes. Bar graph displays the number in the memory table and transform the current values within preset values of -100%~+100% of the percentage value displayed; a line chart in the form of intuitive, sequence number value to the preset values of memory tables within the -100%~+100% of the percentage value displayed; trend chart that shows the digital memory table graphic and numerical changes with time. Converts the numeric value within a predetermined value -100%~+100% the percentage value displayed. Trends over time moved locations. Can also record data in the past, even when there are no displays a trend chart can be read (sampled) digital memory tables.
Users can be selected by pressing the touch switch stop sampling, duplication of data sampling or displays the past three display modes.
