One sequence of operations is set as one scan, and the time required is set as the scan time.

The output devices are updated according to the ladder program.

The input device values are applied to the ladder program.

Processing other than the ladder processing is called the END processing.

The ON/OFF status of the input terminal (external input) is applied to the input circuit. The input refresh loads the external input status into the input devices (I) by way of the input circuit. A delay occurs until the ON/OFF status of the input circuit is applied to the input devices (I). The delay time is equal to filter time + 1 scan time.

The output refresh applies the status of the output devices (Q) to the output circuit, and then the ON/OFF status of the output terminals (external input) is updated. A delay occurs until the values of the output devices (Q) are applied to the output circuit. The delay time is at maximum 1 scan time.

PERATION BASICS

Ladder Program Operation

The FC6A Series MicroSmart performs the following operations to process ladder programs.

Notes:

• The delay time of the hardware is added to the actual input and output delay times. For details on the hardware input/output delay times, see Chapter 2 "Product Specifications" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".

• The filter time differs depending on the input used.

• When the input is a CPU module input (I0 to I27)

Structure of an Advanced Instruction

Opcode

The opcode is a symbol used to identify the advanced instruction.

Data Type

Specifies word (W), integer (I), double word (D), long (L), or float (F) data.

Source Device

The source device specifies the 16- or 32-bit data to be processed by the advanced instruction. Some advanced instructions require two source devices.

Repeat Designation

Specifies whether repeat is used for the device or not.

Repeat Cycles

Specifies the quantity of repeat cycles: 1 through 99.

Destination Device

The destination device specifies the 16- or 32-bit data to store the result of the advanced instruction. Some advanced instructions require two destination devices.

Input Condition for Advanced Instructions

Almost all advanced instructions must be preceded by a contact, except NOP (no operation), LABEL (label), and LRET (label return) instructions. The input condition can be programmed using a bit device such as input, output, internal relay, or shift register. Timer and counter can also be used as an input condition to turn on the contact when the timer times out or the counter counts out.

While the input condition is on, the advanced instruction is executed in each scan. To execute the advanced instruction only at the rising or falling edge of the input, use the SOTU or SOTD instruction.

While the input condition is off, the advanced instruction is not executed and device statuses are held.

Source and Destination Devices

The source and destination devices specify 16- or 32-bit data, depending on the selected data type. When a bit device such as input, output, internal relay, or shift register is designated as a source or destination device, 16 or 32 points starting with the designated number are processed as source or destination data. When a word device such as timer or counter is designated as a source device, the current value is read as source data. When a timer or counter is designated as a destination device, the result of the advanced instruction is set to the preset value for the timer or counter. When a data register is designated as a source or destination device, the data is read from or written to the designated data register.

Using Timer or Counter as Source Device

Since all timer instructions—TML (1-s timer), TIM (100-ms timer), TMH (10-ms timer), and TMS (1-ms timer) — subtract from the preset value, the current value is decremented from the preset value and indicates the remaining time. As described above, when a timer is designated as a source device of an advanced instruction, the current value, or the remaining time, of the timer is read as source data. Adding counters CNT start counting at 0, and the current value is incremented up to the preset value. Reversible counters CDP and CUD start counting at the preset value and the current value is incremented or decremented from the preset value. When any counter is designated as a source device of an advanced instruction, the current value is read as source data.

Using Timer or Counter as Destination Device

As described above, when a timer or counter is designated as a destination device of an advanced instruction, the result of the advanced instruction is set to the preset value of the timer or counter. Timer and counter preset values can be 0 through 65,535.

When a timer or counter preset value is designated using a data register, the timer or counter cannot be designated as a destination of an advanced instruction. When executing such an advanced instruction, a user program execution error will result. For details of user program execution error, see Chapter 13 "User Program Execution Error" in the "FC6A Series MicroSmart All-in-One Type User's Manual".

Note: When a user program execution error occurs, the result is not set to the destination.

Floating-Point Data Format

The FC6A Series MicroSmart can specify floating-point data (F) for advanced instructions. Like double word (D) and long integer (L) data, floating-point data also uses two consecutive data registers to execute advanced instructions. The FC6A Series MicroSmart supports the floating-point data based on the single storage format of the IEEE (The Institute of Electrical and Electronics Engineers) Standard 754.

Single Storage Format

The IEEE single storage format consists of three fields: a 23-bit fraction, f; an 8-bit biased exponent, e; and 1-bit sign, s. These fields are stored contiguously in one 32-bit word, as shown in the figure below. Bits 0:22 contain the 23-bit fraction, f, with bit 0 being the least significant bit of the fraction and bit 22 being the most significant; bits 23:30 contain the 8-bit biased exponent, e, with bit 23 being the least significant bit of the biased exponent and bit 30 being the most significant; and the highest-order bit 31 contains the sign bit, s.

The table below shows the correspondence between the values of the three constituent fields s, e, and f and the value represented by the single storage format bit pattern. When any value out of the bit pattern is entered to the advanced instruction or when execution of advanced instructions, such as division by zero, has produced any value out of the bit pattern, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart.

User Program Execution Errors

When an advanced instruction is executed, a user program execution error occurs when any of the following conditions are met.

• the result of the adavnced instruction is invalid

• source or destination device that is indirectly specified in the advanced instruction exceeds the valid device range

• the advanced instruction does not operate correctly

For example, the data in the source device does not comply with the normal floating-point format when the data type is Float (F). For details about device ranges, see "Devices" on page 2-1.

When a user program execution error occurs, special internal relay M8004 turns on and the corresponding error code is stored in special data register D8006. For details about the error codes, see Chapter 13 "User Program Execution Error" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".

When a user program execution error occurs, instructions operate as follows:

• When the source data is invalid, the execution of the advanced instruction is canceled and the data in the destination device is not changed.

• When the execution result is invalid, a value is stored in the destination device. For details on stored values, see the descriptions of relevant instructions.

• If a user program execution error occurred during a repeat operation, the operation is canceled and the next repeat operation is executed. M8004 is retained even when no further user program execution errors occur during subsequent repeat operations.

Example: User program execution error during a repeat operation

When the source data does not comply with the normal floating-point format.

When the second repeat operation is executed, special internal relay M8004 turns on because the source data is not a normal number in floating-point format.

The second repeat operation is canceled and the third repeat operation is executed.

Carry and Borrow

When the result of an operation exceeds the valid device range, a carry (CY) or borrow (BW) occurs.

Carrying and borrowing occur in the following conditions according to the data type:

Data Type Status

Word Exceeds range between 0 and 65,535

Integer Exceeds range between -32,768 and 32,767

Double Word Exceeds range between 0 and 4,294,967,295

Long Exceeds range between -2,147,483,648 and 2,147,483,647

If an overflow or underflow occurs

Float

When a carry or borrow occurs, special internal relay M8003 (carry and borrow) turns on.

For example, when D0 has a value of FFFF (hex) and +1 is added using an INC instruction, the result is 10000 (hex), but when the data type is Word (W), 0000 (hex) is stored in D0 and 1 is stored in M8003.

Discontinuity of Device Areas

Each device area is discrete and does not continue, for example, from input to output or from output to internal relay. In addition, special internal relays M8000 through M8317 are in a separate area from internal relays M0 through M7997 and M10000 through M17497. Data registers D0 through D7999 and D10000 through D55999, and special data registers D8000 through D8499 are in separate areas and do not continue with each other.

The internal relay ends at M7997. Since the MOV (move) instruction reads 16 internal relays, the last internal relay exceeds the valid range, resulting in a user program syntax error.

This program results in a user program syntax error. The destination of the MUL (multiplication) instruction requires two data registers D55999 and D56000. Since D56000 exceeds the valid range, a user program syntax error occurs.

Advanced instructions execute operation only on the available devices in the valid area. If a user program syntax error is found during programming, WindLDR rejects the program instruction and shows an error message.

The MOV (move) instruction sets data of data register D0 to 16 internal relays M7980 through M7997 in the first repeat cycle. The destination of the second cycle is the next 16 internal relays M8000 through M8017, which are invalid, resulting in a user program syntax error.

For details about repeat operations of each advanced instruction, see the following chapters.

NOP (No Operation)

No operation is executed by the NOP instruction.

The NOP instruction may serve as a place holder. It can also be used to add a delay to the CPU scan time, in order to simulate communication with a machine or application, for debugging purposes.

The NOP instruction does not require an input and device.

Details of the other advanced instructions are described in the following chapters.

Multiple OUT and OUTN

There is no limit to the number of OUT and OUTN instructions that can be programmed into one rung.

Programming multiple outputs of the same output number is not recommended. However, if doing so, it is good practice to separate the outputs with the JMP/JEND set of instructions, or the MCS/MCR set of instructions. These instructions are detailed later in this chapter.

When the same output number is programmed more than once within one scan, the output nearest to the END instruction is given priority for outputting. In the example on the right, output Q0 is off.

ASIC INSTRUCTIONS

Timer Circuit

The preset value 0 through 65,535 can be designated using a data register D0 thorough D7999 or D10000 through D55999; then the data of the data register becomes the preset value. Directly after the TML, TIM, TMH, or TMS instruction, the OUT, OUTN, SET, RST, TML, TIM, TMH, TMS, TMLO, TIMO, TMHO, or TMSO instruction can be programmed.

• Countdown from the preset value is initiated when the operation result directly before the timer input is on.

• The timer output turns on when the current value (timed value) reaches 0.

• The current value returns to the preset value when the timer input is off.

• Timer preset and current values can be changed using WindLDR without downloading the entire program to the CPU again. From the WindLDR menu bar, select Online > Monitor > Monitor, then Online > Custom > New Custom Monitor.

• If a timer preset value is changed during countdown, the timer remains unchanged for that cycle. The change will be reflected in the next time cycle.

• If a timer preset value is changed to 0, then the timer stops operation, and the timer output is turned on immediately.

• If a current value is changed during countdown, the change becomes effective immediately.

• For data movement when changing, confirming, and clearing preset values, see "Changing, Confirming, and Clearing Preset Values for Timers and Counters" on page 4-17. Preset values can also be changed and confirmed using the LCD screen and pushbuttons.

• WindLDR ladder diagrams show TP (timer preset value) and TC (timer current value) in advanced instruction devices.

• The timer instructions (TML, TIM, TMH, TMS) and off-delay timer instructions (TMLO, TIMO, TMHO, TMSO) cannot be used in an interrupt program.

• If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart. For details about the user program execution errors, see "User Program Execution Errors" on page 3-10.

Timer Accuracy

Timer accuracy due to software configuration depends on three factors: timer input error, timer counting error, and timeout output error. These errors are not constant but vary with the user program and other causes.

Timer Input Error

The input status is read at the END processing and stored to the input RAM. So, an error occurs depending on the timing when the timer input turns on in a scan cycle. The same error occurs on normal input and catch input. The timer input error shown below does not include input delay caused by the hardware.

• A single counter number cannot be programmed more than once.

• While the reset input is off, the counter counts the leading edges of pulse inputs and compares them with the preset value.

• When the current value reaches the preset value, the counter turns output on. The output stays on until the reset input is turned on.

• When the reset input changes from off to on, the current value is reset.

• When the reset input is on, all pulse inputs are ignored.

• The reset input must be turned off before counting may begin.

• When power is off, the counter’s current value is held, and can also be designated as “clear” type counters using Function Area Settings (see Chapter 5 "Memory Backup" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".).

• Counter preset and current values can be changed using WindLDR without downloading the entire program to the CPU again. From the WindLDR menu bar, select Online > Monitor > Monitor, then Online > Custom > New Custom Monitor. Change the current value while the counter reset input is off.

• When the preset or current value is changed during counter operation, the change becomes effective immediately.

• When power is off, the preset values that were changed are cleared and the original preset values are loaded.

• WindLDR ladder diagrams show CP (counter preset value) and CC (counter current value) in advanced instruction devices.

• The CNT instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart.

The circuit for a dual-pulse reversible counter must be programmed in the following order: preset input, up-pulse input, down-pulse input, the CDP instruction, and a counter number C0 through C511, followed by a counter preset value from 0 to 65,535. The preset value can be designated using a decimal constant or a data register. When a data register is used, the data of the data register becomes the preset value.

Note: For restrictions on ladder programming of counter instructions, see "Restriction on Ladder Programming" on page 4-31.

Counter Operation after Count out

When the counter has counted out, either the current value or preset value is changed.

Before the counter has counted out, the current value is changed to a larger value than the preset.

The preset value is changed to 0. The counter output is turned on without regard to the current value.

When the reset input is on, the preset value is changed to 0. The counter output is not turned on.

ASIC INSTRUCTIONS

• A single counter number cannot be programmed more than once.

• The preset input must be turned on initially so that the current value returns to the preset value.

• The preset input must be turned off before counting may begin.

• When the up pulse and down pulses are on simultaneously, no pulse is counted.

• The counter output is on only when the current value is 0.

• After the current value reaches 0 (counting down), it changes to 65,535 on the next count down.

• After the current value reaches 65,535 (counting up), it changes to 0 on the next up count.

• When power is off, the counter’s current value is held, and can also be designated as “clear” type counters using the Function Area Settings (see Chapter 5 "Memory Backup" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".).

• Counter preset and current values can be changed using WindLDR without downloading the entire program to the CPU again. From the WindLDR menu bar, select Online >

Monitor > Monitor, then Online > Custom > New Custom Monitor. Change the current value while the

counter preset input is off.

• When the preset or current value is changed during counter operation, the change becomes effective immediately.

• When power is off, the changed preset values are cleared and the original preset values are loaded.

• WindLDR ladder diagrams show CP (counter preset value) and CC (counter current value) in advanced instruction devices. The CDP instruction cannot be used in an interrupt program.

Condition Counter Output

The counter maintains the counted out status.

CNTD, CDPD, and CUDD (Double-Word Counter)

Three types of double-word counters are available; adding (up) counter CNTD, dual-pulse reversible counter CDPD, and up/down selection reversible counter CUDD. A total of 512 double-word counters can be programmed in a user program. Each double-word counter uses 2 consecutive devices starting with the allocated device, which can be C0 through C510. Once used in a user program, counters cannot be used in any other counter instructions.

Counter Device Address Preset Value

CNTD (double-word adding counter) C0 to C510 Constant: 0 to 4,294,967,295

CDPD (double-word dual-pulse reversible counter) C0 to C510

CUDD (double-word up/down selection reversible counter) C0 to C510

For details about device ranges, see "Device Addresses" on page 2-1. The preset value can be 0 through 4,294,967,295 and designated using a constant or a data register. If a data register is designated as the preset value, two consecutive data registers are used.

CNTD (Double-Word Adding Counter)

For a constant, specify the value in the range of 0 to 4,294,967,295. To indirectly specify the value, specify it with a data register number, and specify the value of the data register in the range of 0 to 4,294,967,295. The preset value can be designated using a constant or a data register. When a data register is used, the double-word data of two consecutive data registers becomes the preset value. For 32-bit data storage setting, see Chapter 5 "32-bit Data Storage Setting" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".

Data registers: D0 to D7999

D10000 to D55999

• Double-word counter instructions use two consecutive counters, and counters cannot be used more than once in a user program.

• While the reset input is off, the counter counts the leading edges of pulse inputs and compares them with the preset value.

• When the current value reaches the preset value, the counter turns output on. The output stays on until the reset input is turned on.

• When the reset input changes from off to on, the current value is reset.

• When the reset input is on, all pulse inputs are ignored.

• The reset input must be turned off before counting may begin.

• Counter preset and current values can be changed using WindLDR without downloading the entire program to the CPU again.

The CC= instruction is an equivalent comparison instruction for counter current values. This instruction will constantly compare current values to the value that has been programmed in. When the counter value equals the given value, the desired output will be initiated.

The CC>= instruction is an equal to or greater than comparison instruction for counter current values. This instruction will constantly compare current values to the value that has been programmed in. When the counter value is equal to or greater than the given value, the desired output will be initiated.

When a counter comparison instruction is programmed, two addresses are required. For a constant, specify the value in the range of 0 to 65,535.

To indirectly specify the value, specify it with a data register number, and specify the value of the data register in the range of 0 to 65,535.

The preset value can be designated using a decimal constant or a data register D0 through D1999. When a data register is used, the data of the data register becomes the preset value.

• The CC= and CC>= instructions can be used repeatedly for different preset values.

• The comparison instructions only compare the current value. The status of the counter does not affect this function.

• The comparison instructions also serve as an implicit LOD instruction.

• The comparison instructions can be used with internal relays, which are ANDed or ORed at a separate program address.

• Like the LOD instruction, the comparison instructions can be followed by the AND and OR instructions.

SFR and SFRN (Forward and Reverse Shift Register)

FC6A Series MicroSmart have a shift register consisting of 256 bits which are allocated to R0 through R255. Any number of available bits can be selected to form a train of bits which store on or off status. The on/off data of constituent bits is shifted in the forward direction (forward shift register) or in the reverse direction (reverse shift register) when a pulse input is turned on.

Forward Shift Register (SFR)

When SFR instructions are programmed, two addresses are always required. The SFR instruction is entered, followed by a shift register number selected from appropriate device addresses. The shift register number corresponds to the first, or head bit. The number of bits is the second required address after the SFR instruction.

The SFR instruction requires three inputs. The forward shift register circuit must be programmed in the following order: reset input, pulse input, data input, and the SFR instruction, followed by the first bit and the number of bits.

Reset Input

The reset input will cause the value of each bit of the shift register to return to zero. Initialize pulse special internal relay, M8120, may be used to initialize the shift register at start-up.

Pulse Input

The pulse input triggers the data to shift. The shift is in the forward direction for a forward shift register and in reverse for a reverse shift register. A data shift will occur upon the leading edge of a pulse; that is, when the pulse been on and stays on, no data shift will occur.

Data Input

The data input is the information which is shifted into the first bit when a forward data shift occurs, or into the last bit when a reverse data shift occurs.

Note: When power is turned off, the statuses of all shift register bits are normally cleared. It is also possible to maintain the statuses of shift register bits by using the Function Area Settings as required. See Chapter 5 "Functions and Settings" - "Memory Backup" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".

Reverse Shift Register (SFRN)

For reverse shifting, use the SFRN instruction. When SFRN instructions are programmed, two addresses are always required. The SFRN instructions are entered, followed by a shift register number selected from appropriate device addresses. The shift register number corresponds to the lowest bit number in a string. The number of bits is the second required address after the SFRN instructions.

The SFRN instruction requires three inputs. The reverse shift register circuit must be programmed in the following order: reset input, pulse input, data input, and the SFRN instruction, followed by the last bit and the number of bits.

• The last bit status output can be programmed directly after the SFRN instruction. In this example, the status of bit R20 is read to output Q0.

• Each bit can be loaded using the LOD R# instructions.

• For details of reset, pulse, and data inputs, see "Forward Shift Register (SFR)" on page 4-22.

Note: Output is initiated only for those bits highlighted in bold print.

Note: When power is turned off, the st atuses of all shift register bits are norm ally cleared. It is also possible to maintain the statuses of shift register

bits by using the Function Area Settings as required. See Chapter 5 "Functions and Settings" - "Memory Backup" in the "FC6A Series MicroSmart Allin-One Type User’s Manual".

Note: The SFRN instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart. For details about the user program execution errors, see "User Program Execution Errors" on page 3-10.

Note: For restrictions on ladder programming of shift register instructions, see "Restriction on Ladder Programming" on page 4-31.

SOTU and SOTD (Single Output Up and Down)

The SOTU instruction “looks for” the transition of a given input from off to on. The SOTD instruction looks for the transition of a given input from on to off. When this transition occurs, the desired output will turn on for the length of one scan. The SOTU or SOTD instruction converts an input signal to a “one-shot” pulse signal.

A total of 1,024 SOTU and SOTD instructions can be used in a user program.

If operation is started while the given input is already on, the SOTU output will not turn on. The transition from off to on is what triggers the SOTU instruction.

The SOTU or SOTD instructions cannot be used in an interrupt program.

If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart. For details about the user program execution errors, see "User Program Execution Errors" on page 3-10.

When a CPU relay is defined as the SOTU or SOTD output, it may not operate if the scan time is not compatible with relay requirements.

Note: For restrictions on ladder programming of SOTU and SOTD instructions, see "Restriction on Ladder Programming" on page 4-31.

Note: “T” equals one scan time (one-shot pulse).

There is a special case when the SOTU and SOTD instructions are used between the MCS and MCR instructions (see "MCS and MCR (Master Control Set and Reset)" on page 4-27). If input I2 to the SOTU instruction turns on while input I1 to the MCS instruction is on, then the SOTU output turns on. If input I2 to the SOTD instruction turns off while input I1 is on, then the SOTD output turns on. If input I1 turns on while input I2 is on, then the SOTU output turns on. However, if input I1 turns off while input I2 is on, then the SOTD output does not turn on as shown below.

MCS and MCR (Master Control Set and Reset)

The MCS (master control set) instruction is usually used in combination with the MCR (master control reset) instruction. The MCS instruction can also be used with the END instruction, instead of the MCR instruction.

When the input preceding the MCS instruction is off, the MCS is executed so that all inputs to the portion between the MCS and the MCR are forced off. When the input preceding the MCS instruction is on, the MCS is not executed so that the program following it is executed according to the actual input statuses.

When the input condition to the MCS instruction is off and the MCS is executed, other instructions between the MCS and MCR are executed as follows:

Instruction Status

SOTU Rising edges (ON pulses) are not detected.

SOTD Falling edges (OFF pulses) are not detected.

OUT All are turned off.

OUTN All are turned on.

SET and RST All are held in current status.

Current values are reset to zero. Timeout statuses are turned off.

Current values are held. Pulse inputs are turned off. Countout statuses are turned off.

Shift register bit statuses are held. Pulse inputs are turned off. The output from the last bit is turned off.

Input conditions cannot be set for the MCR instruction.

More than one MCS instruction can be used with one MCR instruction.

Corresponding MCS/MCR instructions cannot be nested within another pair of corresponding MCS/MCR instructions.

JMP (Jump) and JEND (Jump End)

The JMP (jump) instruction is usually used in combination with the JEND (jump end) instruction. At the end of a program, the JMP instruction can also be used with the END instruction, instead of the JEND instruction.

These instructions are used to proceed through the portion of the program between the JMP and the JEND This is similar to the MCS/MCR instructions, except that the portion of the program between the MCS and MCR instruction executed.

When the operation result immediately before the JMP instruction is on, the JMP is valid and the program is the operation result immediately before the JMP instruction is off, the JMP is invalid and the program is executed.

When the input condition to the JMP instruction is on and the JMP is executed, other instructions between the JMP and JEND are executed as follows:
