3. Input/Output Signals

3.1 Input/Output Signal Types and Processing

The input/output signals handled in user PLC are as follows: (1) Input/output from/to controller (2) Input/output from/to operation board (Note 1) (3) Input/output from/to machine

The user PLC does not directly input or output these signals from or to hardware or controller; it inputs

or outputs the signals from or to input/output image memory. For the reading and writing with the hardware or controller, the controller will perform the input/output according to the level of the main process or high-speed process.

3.2 Handling of Input Signals Designated for High-Speed Input

The input/output signals used in user PLC are input/output for each program level as shown in

Fig. 3.1-2.

In high-speed processing, input/output signal for which high-speed input or output designation

(parameter) is made is input or output each time the high-speed processing program runs. In main processing, signals other than interrupt input signals or high-speed input/output designation are input/output.

When high-speed input designation signal is used in main processing, the input signal may change within one scan because high-speed processing whose level is higher than main processing interrupts. Input signal which must not change within one scan should be saved in temporary memory (M), etc., at the head of main processing and the temporary memory should be used in the main program, for example.

The hatched area is high-speed input designation part. Whenever the high-speed processing

program runs, data is reset in the hatched area. Thus, the signal in the hatched area may change in main processing (A) and (B) because the high-speed process interrupts between (A) and (B) and re-reads the input signal in the hatched area.

3. Input/Output Signals

3.3 High-Speed Input/output Designation Method

High-speed input/output is designated by setting the corresponding bit of the bit selection parameter

as shown below.

(1) High-speed input designation

(2) High-speed output designation

· As listed above, one bit corresponds to two bytes (16 points).

· Input or output in which 1 is set in the table is not performed at the main processing program level.

· Although the number of bits set to 1 is not limited, set only necessary ones from viewpoint of overhead.

· High-speed input/output designation corresponds to the bit selection parameter and can be set in the parameter. However, it is recommended to set in a sequence program to prevent a parameter setting error, etc.

Example: —[MOV H3 R2928]— ..... To designate X00~X0F, X10~X1F (bit 0 and 1 for H3)

3.4 Limits for Using High Speed Processing Program

3.4.1 Separation of Main Processing and High Speed Processing Bit Operation Areas

(1) Bit operation area

When using high speed processing, the bit operation range such as the temporary memory is

separated from the main process.

(Method 1) When using the same M or G code, the bit operation area for high speed processing

and the bit operation area for main processing are separated by 64 points or more and used.

For example, the following is used M0 to M4735 for main processing Separate by 64 points or more M4800 to M5120 for high speed processing (M4736 to M4799 are not used)

(Method 2) M is used for the main processing temporary memory and G is used for the high

speed processing temporary memory.

(Note 1) The output devices handled with high speed processing must be limited to M or Y, D

and R.

(Note 2) These limits apply not only to the OUT command, but also to the PLF, PLS, SET, RST

and MOV command, etc., outputs. The devices apply to all devices including M, F, L, SM, T and C.

- 7 -

Interlock Output to NC

Separated by 64 points or mpre during the MOV command.

3. Input/Output Signals

(2) Data area

Even with commands that handle data (numerical values) during the MOV command, etc., the bit

area must be separated by 64 points or more and the data register (D) and file register (R) separated by four registers or more.

Example) Use D0 to D896 for main processing

Use D900 to D1023 for high speed processing

Separate by four registers or more

3.4.2 Separation of Remote I/O Output

When handling high speed output during the high speed process, the main processing output and

high speed processing output cannot be used together in the same remote I/O unit (32 points in channel No. setting rotary switch). A separate 32 points for high speed processing output or a 16-point remote I/O unit will be required.

MOV commands, etc., that extend over differing remote I/O units must not be enforced during either

main processing or high speed processing. If these must be enforced, the channel No. setting rotary switch for the output unit used in the main processing and the output unit used for the high speed processing must be set 1 or more apart.

M10

- 8 -

3. Input/Output Signals

(Usage example 1) Avoid interference with the main process by assigning 7 (last channel) for the

channel No. rotary switch for high speed processing output.

For example, use YE0 to YFF (for 32-point DO-L) or YE0 to YEF (for 16-point

DO-R) as the high speed processing output. (Refer to <Usage examples 1-1, 1-2 and 1-3> below.) (Usage example 2) Assign Y0 to Y1F (32-point) for high speed processing, and use Y20 and

following for the main process. (Refer to <Usage example 2> below.) (Usage example 3) Assign the device after the device used for main processing for the high speed

process. For example, if the devices up to Y2D are used for the main process, use Y40 to

Y5F (channel No. setting rotary switch No.: 2) for the high speed process. (Refer to <Usage example 3> below.)

Relation of channel No. setting switch and device No.

(Devices are YE0 and following)

DX35*/45* DX100 DX100

/120

Usage examples 1-2 show the assignment for the 16-poi nt unit as the No. of high speed output points is relatively low.

(0.1 to 3267.7 s). The data register (D) data can also be used as the setting value. File register (R) cannot be used.

(e) When the bit selection parameter (#6449 bit2=1) is set, the 100ms integrated timer current value

(count value) will be held even when the power is turned OFF.

(2) With the device T, the contact • coil is handled as bit device, and the current value is handled as

word device. In the function commands described after, the word device T indicates the current value even if there is no description about it.

(3) When #6449 bit0=0 is set, timer value can be specified with the parameter set in the setting and

display unit. At this time, the relationship between timer device and parameter is as shown below.

Device Parameter T0 to T15 T56 to T135 T232 to T239

#6000 to #6015 #6016 to #6095 #6096 to #6103

(Note 1) T16 to T55, T136 to T231, and T240 to T255 are specified with a program (Kn) regardless of

#6449 bit0.

(Note2) Even when #6449 bit0=0, Kn is required for a sequence program. Note that, however, the Kn

value is invalid.

(Note 3) When the data register (D) is used as setting value, the data register (D) details will be the

setting value regardless of #6449 bit0.

5. Explanation of Devices

5.3.5 Counter C

(1) The counter counts up and detects the rising edge of the input conditions. Thus, the count will not

take place when the input conditions are ON.

Counter C

(a) The value is set with a decimal, and can be designated from 1 to 32767. The data register (D)

data can also be used as the setting value. File register (R) cannot be used.

(b) The counter count value will not be cleared even if the input conditions turn OFF. The counter

count value must be cleared with the RST command.

(c) When the bit selection parameter is set, the counter current value (count value) will be held

even when the power is turned OFF. Note that some can not be held depending on the version of CNC.

(2) With the device C, the contact • coil is handled as bit device, and the current value (counter

value) is handled as word device. In the function commands described after, the word device C indicates the current value (counter value) even if there is no description about it.

(3) The counter setting value can be set with the setting and display unit using device C. (Variable

counter)

Whether the setting value (Kn) programmed with the sequence program or the setting value set

from the setting and display unit is valid is selected with the bit selection parameters. The changeover is made in a group for C0 to C23. Even when set from the setting and display unit, the setting value (Kn) program will be required in the sequence program. However, the Kn value will be ignored. When the data register (D) is used for the setting value, the data register (D) details will be used as the setting value regardless of the parameter.

(Note) The setting value for device C24 to C127 of counter C cannot be set from the setting and

display unit.

5.3.6 Data Register D

(1) The data register is the memory that stores the data in the PLC. (2) The data register has a 1-point 16-bit configuration, and can be read and written in 16-bit units. To handle 32-bit data, two points must be used. The data register No. designated with the 32-bit

command will be the low-order 16-bit, and the designated data register No. +1 will be the high-order 16-bit.

The No. of steps of the D+ command is indicated. This is a No. of steps required for the store in the controller. In programming with MELSEC PLC development tool (GX Developer),

the displayed No. of steps may be different from this No. of steps. Description such as "4/5" indicates that the No. of steps is different

depending on the designation device. For the 32-bit command, two steps are required for the constant. In the example for the D+ command, if S2 is the word device, the No. of steps will be 4 steps, and if S2 is the constant, the No. of steps will be 5 steps.

The commands that can use an index (Z) are circled. Such a command is only the MOV command in this manual.

Recent sequence programs that require more advanced control cannot provide sufficient control only

with basic commands and thus need four-rule operation and comparison, etc.

Many function commands have been prepared for this. There are approx. 76 types of function

commands.

Each command is explained in the following section.
