I/O DATA DESCRIPTIONS
MODULE STATUS, ERROR STATUS, DATA ERROR STATUS
Shows each module's availability and error status.
15
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.
15
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.
15
16-POINT DISCRETE DATA (models: R3-DA16 and DC16)
15
0 : OFF (open)
1 : ON (close)
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.
