•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 modules
turns to "1."
R3-TSx, R3-RSx, R3-US4: Input burnout
R3-DA16A:
R3-YSx:
•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%) status
for each module. The bit corresponding to such modules turns to "1."
•RX(n+3) through RX(n+m*7–2) are unused.
•RX(n+m*7–1)0 through RX(n+m*7–1)7 are reserved for future use. RX(n+m*7–1)B is assigned to Ready signal, which is
turned to "1" when the network module is in normal conditions. RX(n+m*7–1)8 through RX(n+m*7–1)A, RX(n+m*7–1)C
through RX(n+m*7–1)F are not used.
