I/O DATA DESCRIPTIONS
■
OPERATION IN CASE OF A COMMUNICATION ERROR WITH I/O MODULES
When the communication between the network module and the I/O modules is lost due to an error in an input module, the
last process values are held until the communication is re-established.

ANALOG DATA (16-bit data, models: R30SV4, R30SV2, R30YV4, R30YS4, R30US4, etc.)
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.

ANALOG DATA (16-bit data, models: R30RS4, R30TS4, R30US4, etc.)
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.

ANALOG DATA (16-bit data, models: R30CT4E etc.)
16-bit binary data.
Integer that engineering unit value (A) multiplied by 100 (for CLSE-R5, integer that engineering unit value (A) multiplied
by 1000).

ANALOG DATA (32-bit data, models: R3-PA2, PA4A, WT1, WT4, etc.)
32-bit binary data is used for accumulated counts, encoder positions and active energy.
Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.

ANALOG DATA (32-bit data, models: R3-BA32A, BC32A, etc.)
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.
