• Module Status
RX(n+0)0 through RX(n+0)F indicate whether individual I/O module are mounted or not. The bit corresponding to the
mounted slots turns to “1,” and the unmounted slots to “0.”
• Error Status
RX(n+1)0 through Rx(n+1)F indicate error status for each module as described below. The bit corresponding to such mod-
ules turns to “1.”
R3-TSx, R3-RSx, R3-US4: Input burnout
R3-DA16A:
Power input in error or disconnected
R3-YSx:
Output current error (e.g. load unconnected)
• Data Error Status
RX(n+2)0 through Rx(n+2)F indicate overrange (R3-US4: out of -10% to +110%; the other types: out of -15% to +115%) sta-
tus for each module. The bit corresponding to such modules turns to “1.”
• RX(n+3) through RX(n+6) are unused.
RX(n+8) through RX(n+14) are unused.
• RX(n+7)0 through RX(n+7)7 are reserved for future use. RX(n+7)B is assigned to Ready signal for ASIC 0, which is
turned to “1” when the network module is in normal conditions. RX(n+7)8 through RX(n+7)A, RX(n+7)C through RX(n+7)F
are not used.
RX(n+15)0 through RX(n+15)7 are reserved for future use. RX(n+15)B is assigned to Ready signal for ASIC 1, which
is turned to “1” when the network module is in normal conditions. RX(n+15)8 through RX(n+15)A, RX(n+15)C through
RX(n+15)F are not used.
