• Module Status

RX(n+0)0 through RX(n+0)F indicate whether individual I/O modules are mounted or not. The bit corresponding to the mounted

slot turns to “1,” and the unmounted slot 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 module

turns to “1.”

R3-TSx, -RSx, -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%) status

for each module. The bit corresponding to such module 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.
