Automatically turns OFF when reset is complete.09RS-232C Port Reset BitAutomatically turns OFF when reset is complete.PC Setup Reset BitTurn ON to initialize PC Setup (DM 6600 through DM 6655). Automaticallyturns OFF again when reset is complete. Only effective if the PC is in PROGRAM mode.Forced Status Hold BitOFF: The forced status of bits that are forced set/reset is cleared whenswitching between PROGRAM mode and MONITOR mode.ON: The status of bits that are forced set/reset are maintained when switching between PROGRAM mode and MONITOR mode.1011SR 25312I/O Hold BitOFF: IR and LR bits are reset when starting or stopping operation.ON: IR and LR bit status is maintained when starting or stopping operation.1314Not used.Error Log Reset BitTurn ON to clear error log.
Automatically turns OFF again when operation iscomplete.1500 to 07Not used.FAL Error CodeThe error code (a 2-digit number) is stored here when an error occurs. TheFAL number is stored here when FAL(06) or FALS(07) is executed. This wordis reset (to 00) by executing a FAL 00 instruction or by clearing the error froma Programming Device.0809Not used.Cycle Time Overrun FlagTurns ON when a cycle time overrun occurs.Not used.RS-232C Port Set BitTurn ON to set RS-232C port.Turn OFF when reset is complete.10 to 1112131415SR 254Function000102030405060708 to 15Always ON FlagAlways OFF FlagFirst Cycle FlagTurns ON for 1 cycle at the start of operation.1-minute clock pulse (30 seconds ON; 30 seconds OFF)0.02-second clock pulse (0.01 second ON; 0.01 second OFF)Negative (N) FlagNot used.Overflow FlagUnderflow FlagDifferential Monitor Complete FlagTurns ON when differential monitoring is complete.STEP(08) Execution FlagTurns ON for 1 cycle only at the start of process based on STEP(08).Not used.Read/writeRead/writePage24521717Read/write527Readonly355Readonly---Read/writeReadonly-------------Readonly----147356555Appendix CMemory AreasWord(s)SR 255Bit(s)000102030405060708 to 15Function0.1-second clock pulse (0.05 second ON; 0.05 second OFF)0.2-second clock pulse (0.1 second ON; 0.1 second OFF)1.0-second clock pulse (0.5 second ON; 0.5 second OFF)Instruction Execution Error (ER) FlagTurns ON when an error occurs during execution of an instruction.Carry (CY) FlagTurns ON when there is a carry in the results of an instruction execution.Greater Than (GR) FlagTurns ON when the result of a comparison operation is “greater.”Equals (EQ) FlagTurns ON when the result of a comparison operation is “equal,” or when theresult of an instruction execution is 0.Less Than (LE) FlagTurns ON when the result of a comparison operation is “less.”Not used.Read/writeReadonlyPage------------------AR AreaThese bits mainly serve as flags related to SRM1 operation.
