Function
This word contains the data which was requested from the memory
map after a read cycle is executed.
Reserved
This bit signals that an error in the data transfer protocol has
occurred. This includes attempting to write to read-only memory
locations. To recover from a Data Transfer Sequence Error, the PLC
must set the PC Read Finished bit.
This bit indicates if an alarm condition has occurred for a specific
Input Point and corresponds with the respective bit in DM09. The
flag reports only when data is requested from the corresponding
memory locations DM01-08 or DM11-18 and otherwise reports ‘0’.
This bit indicates if an out of range condition has occurred for a
specific Input Point and corresponds with the respective bit in
DM10. The flag reports only when data is requested from the
corresponding memory locations DM01-08 or DM11-18 and
otherwise reports ‘0’.
This bit indicates the configuration for a specific Input Point and
corresponds with the respective bit in DM23. The flag reports only
when data is requested from the corresponding memory locations
DM01-08 or DM11-18 and otherwise reports ‘0’.
This bit indicates if an open RTD has been detected for a specific
Input Point and corresponds with the respective bit in DM83. The
flag reports only when data is requested from the corresponding
memory locations DM01-08 or DM11-18 and otherwise reports ‘0’.
This bit indicates if an alarm condition has occurred for a enabled
Input Point, corresponding with any bit set in DM09, and reports
continuously.
This bit indicates if out of range condition has occurred for any
enabled Input Point, corresponding with any bit set in DM09, and
reports continuously.
This bit toggles ON and OFF at a 1 Hz rate with a 45-55% duty
cycle to indicate that the module is operational.
This bit is set when a calculation resulting in an out of range value is
performed. This can occur with parameter values when the mode is
changed from Binary to BCD. This flag reports continuously.
This bit is set when an attempt is made to write an invalid value or a
value of improper format into parameter locations DM30 thru DM77,
and is cleared on the next valid write cycle. This flag corresponds
with any bit set in Data Error Status DM00 Bits 08-15 and reports
continuously.
This bit indicates if an open RTD condition has occurred for any
enabled Input Point, corresponding with any bit set in DM83, and
reports continuously.
This bit is set by the module to indicate to the PLC that it has read
the data in words N and N+1. It is reset by the module when the PC
Write Finished, Word N+1 Bit 14 is reset by the PLC.
This bit is set by the module to indicate to the PLC that it has written
the requested data into words N+2 and N+3. It is reset by the
module when PC Read Finished, Word N+1 Bit 15 is set by the
PLC.
