•
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 mod-
ule 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)
R3-PC16A:
External power supply in error or disconnected
•
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+6) 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, 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.
