DATA TYPE
I: Integer; 0 to 10000 (0 to 100%)
Note: DO NOT access addresses other than mentioned above.
Accessing such an address may result in problem such as malfunction of the unit.
1) Module Status indicates whether or not an I/O module is mounted on each slot.
The bit corresponding to the mounted slot turns to ‘1’, and the unmounted slot to ‘0’.
2) Error Status indicates occurrence of an error of each module as described below.
The bit corresponding to the module having an error turns to ‘1’.
- R3-TSx, R3x-RSx, R3-US4 (input type: T/C or RTD): Input burnout
- R3x-DA16A: Power input error or disconnection
- R3x-YS4: Output disconnection
- R3-PC16A: External power supply in error or disconnected
3) Data Error Status indicates occurrence of an error of each module as described below.
The bit corresponding to the module having an error turns to ‘1’.
- Analog input modules transmitting 0 to 100% scaling value: Input overrange (≤ -15% or ≥ 115%)
- R30YS4: Output disconnection
- R30TS4, R30RS4, R30USx (input type: T/C or RTD): Input burnout
- R3-TSx, R3x-RSx, R3-US4 (input type: T/C or RTD): Input burnout
- R3-US4 (input type: voltage): Input overrange (≤ -10% or ≥ 110%)
