4-2 Tasks, Sections, and Symbols........
Page 46: Programming
A program consists of more than one instruction and ends with an END instruction. • Tasks (Smallest Executable Unit) A program is assigned to an interrupt task to execute it. (In the CX-Programmer, the interrupt task number is specified in the program properties.)
Page 47: Program Capacity
Basic Concepts of Ladder Programming Instructions are executed in the order that they are stored in memory (i.e., in the order of the mnemonic code). Be sure you understand the concepts of ladder programming, and write the programs in the proper order.
Page 48 Number of Times Bits Can be Used and Connection Method • There is no limit to the number of I/O bits, work bits, timers, and other input bits that can be used. Program structure should be kept as clear and simple as possible to make the programs easier to understand and maintain even if it means using more input bits.
Page 49 One output bit can be used in one instruction only. Instructions in a ladder program are executed in order from the top rung in each cycle. The result of an OUT instruction in a lower rung will be eventually saved in the output bit. The results of any previous instructions controlling the same bit will be overwritten and not output.
Page 50: Tasks, Sections, And Symbols
Overview of Symbols Symbols I/O memory area addresses or constants can be specified by using character strings registered as symbols. The symbols are registered in the symbol table of the CX-Programmer. Programming with symbols enables programming with names without being aware of the addresses.
Page 51 Note “Global” and “local” indicate only the applicable scope of the symbol. They have nothing to do with the applicable scope of memory addresses. Therefore, a warning but not an error will occur in the following cases, and it will be possible to transfer the user program.
Page 52: Programming Instructions
(destinations) I/O memory Power Flow The power flow is the execution condition that is used to control the execution and instructions when programs are executing normally. In a ladder program, power flow represents the status of the exe- cution condition.

Page 63: Specifying Offsets For Addresses
Starting bit address A Start Bit Address It is possible to specify the start bit address with a bit address or with a symbol (except the NUMBER data type cannot be used). Offsetting is possible for all addresses except the DM Areas.
Page 64 If a word address or symbol is specified, the contents of the specified word is used as the offset. If the offset exceeds bit 15 in the specified word, offsetting will continue from bit 00 in the next word. If the offset is specified indirectly, make sure that the final bit address does not exceed the upper limit of the memory area by using input comparison or other instruction.
Page 65: Application Examples For Address Offsets
Application Examples for Address Offsets It is possible to dynamically specify the offset by specifying a word address in I/O memory for the offset in the brackets. The contents of the specified word address will be used as the offset.
Page 66: Ladder Programming Precautions
FOR-NEXT sections Subroutines Place all the subroutines together just after all of the main program and before the END instruction. A subroutine cannot be placed in a step ladder, block program, or FOR-NEXT section. If instructions other than those in a subroutine are placed after a subroutine (SBN to RET), those instructions will not be executed.
Page 67 SBN and RET SUBROUTINE ENTRY and SUBROUTINE RETURN Note A step ladder program section can be used in an interlock section (between IL and ILC). The step ladder section will be completely reset when the interlock condition is ON. CP1E CPU Unit Software User’s Manual(W480)

Page 81: Timer Area (T)
Timer Area (T) Overview The Timer Area contains Timer Completion Flags (1 bit each) and timer PVs (16 bits each). The Com- pletion Flag is turned ON when a decrementing timer PV reaches 0 (counting out) or an increment- ing/decrementing timer PV reaches the set value or 0.
Page 82 Retained lock conditions *1 If the IOM Hold Bit (A500.12) is ON, the PV and Completion Flag will be retained when a fatal error occurs (including execution of FALS instructions) or the operating mode is changed from PROGRAM mode to RUN or MONITOR mode or vice-versa.

Page 85: Auxiliary Area (A)
Precautions for Safe Use • With an E-type CPU Unit or with an N/NA-type CPU Unit without a Battery, the contents of the DM Area (D) *, Holding Area (H), the Counter Present Values (C), the status of Counter Com- pletion Flags (C), and the status of bits in the Auxiliary Area (A) related to clock functions may be unstable when the power supply is turned ON.
Page 86 Details • Some words or bits are set automatically by the system and others are set and manipulated by the user. The Auxiliary Area includes error flags set by self-diagnosis, initial settings, control bits, and status data.
Page 87: Condition Flags
Condition Flags Overview These flags include the flags that indicate the results of instruction execution, as well as the Always ON and Always OFF Flags. These bits are specified with symbols rather than addresses. The CX-Programmer treats condition flags as system-defined symbols (global symbols) beginning with P_.
Page 88 The Condition Flags are shared by all of the instructions. This means that program operation can be changed from its expected course by interruption of a single task. Be sure to consider the effects of interrupts when writing ladder programs to prevent unexpected operation.
Page 89: Clock Pulses
5-10 Clock Pulses Overview The Clock Pulses are turned ON and OFF by the CPU Unit’s internal timer. These bits are specified with symbols rather than addresses. The CX-Programmer treats condition flags as system-defined symbols (global symbols) beginning with P_.

Page 93: I/O Allocation Concepts
For a CPU Unit with 40 I/O points, a total of 24 input bits are allocated to the input terminal block. The bits that are allocated are input bits CIO 0.00 to CIO 0.11 (i.e., bits 00 to 11 in CIO 0) and input bits CIO 1.00 to CIO 1.11 (i.e., bits 00 to 11 in CIO 1).
Page 94: Allocations To Expansion Units And Expansion I/O Units
CPU Unit. For example, if a CPU Unit with 40 I/O points is used, CIO 0 and CIO 1 are allocated for inputs and CIO 100 and CIO 101 are allocated for outputs. Thus, words from CIO 2 onward for inputs and words from CIO 102 onward for outputs are automatically allocated to the Expansion I/O Units and Expansion Units in the order that the Units are connected.
Page 95 Twenty-four input bits in two words are allocated (bits 00 to 11 in CIO m and bits 00 to 11 CIO m+1). Sixteen output bits in two words are allocated in two words (bits 00 to 07 in CIO n and bits 00 to 07 in CIO n+1).

Page 119 Note 1 The same pulse inputs must be used for high-speed counter 0 and high-speed counter 1. 2 High-speed counter 2 cannot be used if the input setting of high-speed counter 0 or high-speed counter 1 is set for differential phase inputs (4×), pulse + direction inputs, or up/down pulse inputs.
Page 120: Allocating Built-In Output Temrinals
Therefore, do not use the input terminals repeatedly. For example, if quick-response input 2 is used, then input terminal 02 is occupied, so it cannot be used for normal input 2, input interrupt 2, quick-response input 2, counter 2 (increment), counter 1 (phase- A/increment) or counter 0 (direction).

Page 434: Response Performance
Minimum I/O response time = Input ON delay + Cycle time + Output ON delay Note The input and output ON delays depend on the type of terminals used on the CPU Unit or the model number of the Unit being used.
Page 435 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 × 2) + 0.1 ms = 41.1 ms Input Constant Setting Input constant setting can be set in the PLC Setup.
Page 436: A-3-2 Interrupt Response Time
* The wait time occurs when there is competition with other interrupts. As a guideline, the wait time will be 0 to 3 ms. Note Input interrupt tasks can be executed during execution of the user program, I/O refresh, peripheral servicing, or overseeing.
Page 437: A-3-3 Serial Plc Link Response Performance
The length of the interrupt response time for scheduled interrupt tasks is 0.1 ms max. There is also an error of 10 µs in the time to the first scheduled interrupt (1.0 ms min.). Note Scheduled interrupt tasks can be executed during execution of the ladder program (even while an instruction is being executed by stopping the execution of an instruction), I/O refresh, peripheral servicing, or overseeing.
Page 438: A-3-4 Pulse Output Start Time
ACC: independent, triangular PLS2: trapezoidal PLS2: triangular * The wait time occurs when there is competition with other interrupts. As a guideline, the wait time will be 0 to 3 ms. A-3-5 Pulse Output Change Response Time The pulse output change response time is the time for any change made by executing an instruction during pulse output to actually affect the pulse output operation.
Page 439: 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.
Page 440: Description Of Operation
Malfunction Countermeasures If only a couple of Expansion I/O Units or Expansion Units are connected to the CPU Unit resulting in a light power supply circuit load and a small current consumption, the time required by the CPU Unit to detect a power interruption will be longer.
Page 441 If the external power supply input turns OFF before the power interruption is detected, the CPU Unit will read the input as being OFF The following diagram shows an example countermeasure for this situation. • Wiring Emergency stop input 100 VAC...
