• RX(n+0) is used as Ready signal, the bit is “1” when this module is in normal.
• Redundant Command Read Back (Opt. code: /W Available only for redundant system PLC by Mitsubishi)
The bit written to RY(n+1)0 reads back to RX(n+1)0.
• Module Status
RX(n+2)0 to RX(n+2)F indicate whether individual I/O modules of R3 series are mounted or not.
The bit corresponding to the mounted slot turns to “1”, and the unmounted slot to “0”
• Error Status
RX(n+3)0 to RX(n+3)F indicate error status for each module of R3 series.
The bit corresponding to such module turns to “1”, as described below.
R3-TSx, R3-RSx, R3-US4 Input burnout.
R3-DA16A input power in error or disconnected
R3-YSx output current error (e.g. load unconnected)
R3-PC16A external power supply in error or disconnected
• Data Error Status
RX(n+4)0 to RX(n+4)F indicate data error status for each module of R3 series.
The bit corresponding to such module turns to “1”, as described below.
Input value is out of -15% to +115%
In the case of R3-US4 (voltage input) input level out of -10% to +110%.
