The preset comparator upper/lower limits are treated as a single data item for two PLC devices. When setting the
data, use little endian format.
In addition, the value to be set is a count value whose last digit conforms to the input resolution. For example, if the
input resolution is 5 μm, the 1’s place corresponds to 1 μm and the values that can be set are multiples of 5.
Set the data according to the following table of possible settings.
Resolution mm setting unit mm/25.4 setting unit
0.1μm 0.1 μm unit
0.00001 mm/25.4 unit
0.5μm 0.1 μm unit
(last digit must be a 5 or 0)
0.00001 mm/25.4 unit
(multiple of 2)
1μm 1 μm unit
0.0001 mm/25.4 unit
5μm 1 μm unit
(last digit must be a 5 or 0)
0.0001 mm/25.4 unit
(multiple of 2)
10μm
10 μm unit 1 (0.001 mm/25.4 unit)
Measurement
data area
When the measurement data request flag is set to ON, the MG80-SC writes measurement data to the following
memory area.
Offset Data name
0x0000 Measurement data 0 (low order)
0x0001 Measurement data 0 (high order)
0x0002 Measurement data 1 (low order)
0x0003 Measurement data 1 (high order)
: :
0x001E Measurement data 15 (low order)
0x001F Measurement data 15 (high order)
0x0020 Comparator result 1
0x0021 Comparator result 2
: :
0x002F Comparator result 16
For a module that has an alarm, 0xA5A5A5A5 is stored in the measurement data and 0x000F is stored in the
comparator result.
