I/O DATA DESCRIPTIONS
■
MODULE STATUS, ERROR STATUS, DATA ERROR STATUS
Shows each module’s availability and error status.
■
ANALOG DATA (models: R3-SV4, YV4, DS4, YS4 and US4)
16-bit binary data.
Basically, 0 to 100% of the selected I/O range is converted into 0 to 10000 (binary). Negative percentage is represented in 2’s
complements.
■
TEMPERATURE DATA (models: R3-RS4, TS4 and US4)
16-bit binary data.
With °C temperature unit, raw data is multiplied by 10. For example, 25.5°C is converted into 255.
With °F temperature unit, the integer section of raw data is directly converted into the data. For example, 135.4°F is con-
verted into 135.
Minus temperature is converted into negative values, represented in 2’s complements.
■
ACCUMULATED COUNT DATA (32-bit data, models: R3-PA2, PA4A, WT1, WT4, etc.)
32-bit binary data is used for accumulated counts and encoder positions.
Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.
32-bit data cannot be accessed using floating addresses.
■
BCD DATA (32-bit data, models: R3-BA32A, BC32A)
32-bit binary data is used for BCD.
Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.
32-bit data cannot be accessed using floating addresses.
