INPUT-OUTPUT RELATION EXAMPLES

• FS
-FS stands for -15 % of the input range (0 to 100 %), which is configured by ITEM 14, display range scaling 0 % and ITEM 15, display range scaling 100 %. +FS stands for +115 % of the input range.

• OR
When one of the following conditions is true, the digital input overflows (OR).
 1) When the input signal is out of the range between -FS and +FS.
 2) When the input value exceeds the input range.
 The input range differs according to input code. For example, in case of BCD with polarity, it is -9999 to 9999. Please refer to the instruction manual for detail.
