*1: LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2: The EM Area is supported only by the C200HX/HG/HE(-Z)E PLCs.
The range of respective area varies with the type of PLC. Refer to Appen-
dix H Special Characters (page 163).
• The bar graph display cannot use hexadecimal numbers. If hexadecimal
numbers are set, the bar graph will not be displayed.
By writing a negative number (whose most significant digit is "F") to the al-
located 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 table entries, refer to 5-3-1 Allocation Words and Dis-
play of Memory Table Entries (page 117).
