The date and time data are stored in signed binary data in a numeral memory
table. Therefore, to display a numeric value, it is necessary to set "Decimal" for
"Display Type".
Register the "numeric value display" for the display of contents of numeral memory
tables No. 247 to No. 253 for the screen according to the date and time data to be
displayed.
The "Display Type" of "Numeral Display" must be "Decimal". Set other properties
according to the display requirements.
The current date and time are continually displayed by the "Numeral Display" for
displaying numeral memory tables No. 247 to No. 253.
The following describes an example of how to display the date and time, set at the
PC, on the NT31/NT31C.
In this example a C200HX, which has a clock function, is used. The clock function
is allocated to words AR18 to AR21 in the C200HX.
