WITH STATUS DATA (SW3-3: ON)
• I/O type: Input
Status data is assigned to the last 2 words.
Data of the slots 6 and 7 is unable.
• I/O type: Input/Output Mixed
Status data is assigned to the last 2 words of the input area.
Data on the words 3 and 4 of the slot 2 is unable.
• I/O type: Output
Status data cannot be assigned because there is no input data.
For output only, operate without status area.
• Module Status indicates whether individual I/O modules are mounted or not. The bit corresponding to the mounted slot
turns to “1,” and the unmounted slot to “0.”
• Error Status indicates error status for each module as described below. The bit corresponding to such module turns to “1.”
R3-TSx, R3-RSx, R3-US4 (T/C, RTD input): Input burnout
R3-DA16A: Power input in error or disconnected
R3-YSx: Output current error (e.g. load unconnected)
Every module which input is less than -15% or more than +115%
R3-US4 (voltage input): out of -10% to +110% input.

I/O DATA DESCRIPTIONS
The data allocations for typical I/O modules are shown below.
Refer to the manual for each module for detailed data allocations.
■
ANALOG DATA (16-bit data, models: R3-SV4, YV4, DS4, YS4 and US4, etc.)
16-bit binary data.
Basically, 0 to 100% of the selected I/O range is converted into 0 to 10000 (binary).
-15 to 0 % is a negative range represented in 2’s complement.
In case of R3-US4, -10 to 0% is a negative range represented in 2’s complement.
