Instruction A m+1 Repeats the process Instruction A ,IR0+...
Page 72 4 Understanding Programming The input condition is OFF (P_Off is the Always OFF Flag), so the SET instruction is not exe- cuted. Therefore, IR0 is not incremented and the value stored in IR0 remains PLC memory address CIO 0.13. • The following instructions are executed even when the interlock is active. Therefore, when indi- rect memory addresses are specified using auto-incrementing or auto-decrementing (,IR+ or ,IR-) in an operand of any of these instructions, the value in the Index Register (IR) is refreshed each cycle regardless of the input condition (increases or decreases one every...
Page 73 4 Understanding Programming Application Example for Index Registers The data in D0 to D99 (augend data) is added to the data in D100 to D199 (addend data) and the addi- tion results are output to D200 to D299. The operands of a single addition instruction are specified by index registers and the addition operations are performed by incrementing the index registers and repeatedly executing the addition instruction.

Page 94 5 I/O Memory Timer PV Refresh Method Timer num- Timer PV refresh method bers T0 to T255 The timer PV is refreshed when the instruction is executed. This can cause a delay depending on the cycle time. • When the cycle time is longer than 100 ms, delay is generated by the TIM/TIMX instruction. •...
Page 95: Counter Area (C)
5 I/O Memory Counter Area (C) Overview The Counter Area contains Completion Flags (1 bit each) and counter PVs (16 bits each). A Comple- tion Flag is turned ON when the counter PV reaches the set value (counting out). Completion Flags and counter PVs are automatically retained in the built-in non-volatile RAM even if the power supply is interrupted.
Page 96 5 I/O Memory Precautions for Correct Use Precautions for Correct Use It is not recommended to use the same counter number in two counter instructions because the counters will not operate correctly if they are counting simultaneously. If two or more counter instructions use the same counter number, an error will be generated dur- ing the program check.
Page 97: Index Registers (Ir)
5 I/O Memory Index Registers (IR) Overview The sixteen Index Registers (IR0 to IR15) are used for indirect addressing. Each Index Register can hold a single PLC memory address, which is the absolute memory address of a word in I/O memory. These are different from the I/O memory area addresses in the CIO Area, DM Area, etc.

Page 560 Appendices Calculation Example Conditions: Input ON delay: 1 ms (normal input 0.08 to 0.11 with input constant set to 0 ms) Output ON delay: 0.1 ms (transistor output) Cycle time: 20 ms Minimum I/O response time = 1 ms + 20 ms + 0.1 ms = 21.1 ms Maximum I/O response time = 1 ms + (20 ms ×...
Page 561 Appendices A-3-2 Interrupt Response Time Interrupt Response Time for Input Interrupt Tasks The interrupt response time for input interrupt tasks is the time taken from when a built-in input has turned ON (or OFF) until the input interrupt task has actually been executed. The length of the interrupt response time for input interrupt tasks depends on the total of the hard- ware interrupt response time and software interrupt response time.
Page 562 Appendices Interrupt Response Time for Scheduled Interrupt Tasks The interrupt response time for scheduled interrupt tasks is the time taken from after the scheduled time specified by the MSKS instruction has elapsed until the interrupt task has actually been exe- cuted.
Page 563 Appendices A-3-4 Pulse Output Start Time The pulse output start time is the time required from executing a pulse output instruction until pulses are output externally. This time depends on the pulse output instruction that is used and operation that is performed. Instruction Start time execution...
Page 564 Appendices PLC Operation for Power Interruptions Overview of Operation for Power Interruptions Power Supply Voltage Drop If the power supply voltage falls below the specified value (85% of rated voltage) while the CPU Unit is in RUN or MONITOR mode, operation will be stopped and all outputs will be turned OFF. Detection of Momentary Power Interruptions The system will continue to run if the momentary power interruption lasts less than 10 ms (2ms for DC power supply).
Page 565 Appendices Power OFF Timing Chart Operation always stopped at this point Power supply voltage: 85% Holding time for 5 V internal power supply after power OFF detection: 1 ms Power OFF detection Power OFF Detection Time AC: 10ms Power OFF DC: 2ms detected signal Program execution...

Page 567 Appendices A-5 Memory Map PLC Memory Addresses PLC memory addresses are set in Index Registers (IR00 to IR15) to indirectly address I/O memory. Normally, use the MOVE TO REGISTER (MOVR(560)) and MOVE TIMER/COUNTER PV TO REGIS- TER (MOVRW(561)) instructions to set PLC memory addresses into the Index Registers. Some instructions, such as FIND MAXIMUM (MAX(182)), and FIND MINIMUM (MIN(183)), output the results of processing to an Index Register to indicate an PLC memory address.
