S Program operation
(1) When an error occurs (bit 09000 turns ON), the NT620S/620C displays the
message "Error".
(2) When the error is cleared (bit 09000 turns OFF), the NT620S/620C display
message reverts to "Normal".
The following describes the procedure to upgrade the graph on the
NT620S/620C by changing the contents of the allocated words.
To change the graph display on the NT620S/620C, change the contents of the
PC words to which the numeral memory tables have been allocated.
The graph display cannot use hexadecimal numbers. If hexadecimal numbers
are set, the graph will not be displayed.
By writing a negative number (whose most significant digit is "F") to the allocated
word of a graph set as "Sign display "No" ", the graph display will become 0 % and
the % display will show "
:::
For the procedure to write numeral values to the allocated words of the numeral
memory tables, refer to "Allocation Words and Display of the Memory Tables"
(page 201).
For the procedure to change the contents of the numeral memory table (PC
