Chapter 1 Features

1. Multifunctional all-in-one type PLC

The MICRO-EH is a multifunctional all-in-one type PLC that contains all necessary parts—a power supply and CPU parts as well as I/O units--within one unit. Three sizes of PLCs are available: 10, 14, and 28 points. A type with 23 points plus three points of analog I/O having the same size as the 28-point PLC is also available. Moreover, for PLCs with more than 14 points, it is possible to install additional 14 or 28 point expansion units up to four units. Thus, the MICRO-EH can control a wide range of systems from small to medium size.

2. Simplified positioning by counter inputs and pulse train outputs

The function of inputs/outputs can be selected from four modes. By selecting a mode, inputs/outputs that are used as normal inputs/outputs can be set as counter inputs and pulse train outputs. Through a combination of these special inputs/outputs, it is possible to control positioning without using special modules.

3. Simplified instrument system by analog integration

For the 23-point PLC, there are two points of analog input and one point of analog output for which both current and voltage can be selected. High performance analog channels, with a resolution of 12 bits and an overall accuracy of ±1 % or less, can be used without requiring special settings of the channels; thus, a simplified instrument system can easily be implemented.

4. Superior upward compatibility

The MICRO-EH has been developed as a part of the EH/H series family. Debugging and programming can be performed using the same concept as for the EH/H series. In addition, the MICRO-EH software property can effectively be applied to the EH/H series for future system expansion.

5. Easy maintenance through removable terminal blocks and installation on a DIN rail

All models of the MICRO-EH series support the DIN rail so that the PLC can easily be mounted and dismounted. In addition, the I/O section of the 14-point PLC or more utilizes a removable terminal block. Thus, erroneous and faulty wiring that may occur when connecting to external devices can be reduced.

6. Remote maintenance through modem connection

Communication with remote sites can be performed via dial-up line by connecting a modem to port 1 on the 14point PLC or more of the MICRO-EH series. It is possible to monitor and manage remote systems from an office or monitor room.

7. Easily adjustable potentiometer

The 14-point PLC or more of the MICRO-EH series supports two potentiometers. By using these potentiometers, it is possible to rewrite internal output values in real-time by one driver without using peripheral devices. Since the resolution of the potentiometer is 10 bits, it is possible to set any value from 0 to 3FFH. To obtain stable analog values of the potentiometers, it is possible to sample 1 to 40 analog values of the potentiometers and average them.

8. Maintaining programs without a battery

It is possible to retain user programs in case of out-of battery or no battery, since FLASH memory is used as the backup memory for the user programs. However, a battery is necessary for data memory backup. (See the Notes in Chapter 7.1 for a list of precautionary details.)

9. Support for various programming languages

The MICRO-EH supports “Pro-H,” the programming software that allows creating programs in five programming languages regulated in IEC1131-3. This means that customers who have learned languages other than Ladder can easily create programs with this programming software.

10. Compliant with overseas specifications as standard

All types of MICRO-EH PLCs have obtained the CE mark, C-TICK and UL. Therefore, systems in which these PLCs are installed can be exported without requiring any modification.

3.2 Function Specifications

The functions available in the MICRO-EH are described in the table below.

No. Item Description

1 Basic functions The following functions can be executed when constructing a system using the PLC.

1] An input signal is received from the control object, operations are performed according to

the contents of the program created by the user and the results are output as an output signal. Also, operation results and progress information can be retained in the internal output area.

2] Power is supplied to the main module, system starts to run, and the operation described

above is performed continuously until the power is shut down or the system stops running.

3] The information retained internally can be extracted by a device connected externally or can

be set in other information. Also, this information is initialized at the time the system starts running, but it can also be retained depending on the user settings.

4] Operating status can be confirmed with the LED display of each unit or with an external

device that has been connected.

2 Setting and display The following have been provided for the user to set or confirm various types of operation

status: 1] DIP switch (basic unit)

This specifies the CPU communication function setting and operation mode, etc. (except for 10-point type)

2] RUN switch (basic unit)

It can instruct to run and stop. (external input for 10-point type)

3] LED display (basic unit and expansion unit)

Indicates the power system status, operating status and I/O operation status.

4] Communication connector (basic unit)

This can connect external devices using RS-232C, RS-485, RS-422. (only the 23-point and 28-point types with RS-485, RS-422)

5] Expansion connector (basic unit and expansion unit)

This allows installation of additional input/output. (except for 10-point type)

6] Terminal block (basic unit and expansion unit)

This performs the connections for supplying power, and for handling signals with the control object.

3 Number of I/O points The number of points that can be controlled with respect to the control object is as follows:

1] External inputs/outputs

The number of points that can be use for external inputs/outputs differs depending on the basic unit. The 10-point type cannot expand the inputs/outputs. For the 14-point, 23-point and 28-point types, a maximum of 4 expansion units can be connected. The I/O numbers for inputs are indicated by X, WX, DX and outputs are indicated by Y, WY, DY.

2] Internal outputs

These are areas for temporarily storing information. The I/O numbers include M, WM, DM,

R, WR, DR. 3] A timer counter is provided internally. 4] Array (corresponding to a substitution statement only)

An array of I/O numbers can be expressed by enclosing by parentheses.

4 User program

memory

The program in which the control contents have been described can be stored. This FLASH memory resides in the basic unit. 1] The contents of this memory will be maintained even if the power is shut off. Because of

this, it is necessary to initialize the memory since it may have undefined after the unit is

purchased. 2] Programming is done using peripheral units such as programming software (LADDER

EDITOR) for the H-series programmable controllers. 3] The instructions that can be used are those designated by the H-series ladder. See the list of

instructions for details. 4] A battery is not required to retain the contents of the user program. Always save the created

programs to a floppy disk just in case an unexpected problem occurs.

Chapter 3 Function and Performance Specifications

3-3

No. Item Description

5 Control method With the PLC, the user programs are converted in batch at operation startup, and the programs

after conversion will be executed in order as they are read one by one. 1] The method used for data I/O is that after the I/O data (information) is scanned (execution

from the head of the program to the end), it is updated in group. If refresh of external I/O is

required during scanning (refresh method), use the refresh instruction. 2] Apart from the program that will be normally executed, a periodic scan program which

interrupts the normal program at a fixed time intervals and is executed, can be created. The

time intervals are 10 ms, 20 ms and 40 ms. 3] The user programs are executed from the head of the program to the end, and are once again

repeated after performing the system processing that updates the lapsed timer value,

refreshes I/O, and performs communication with peripheral units.

6 Run/stop control Running and stopping the PLC is normally performed by the user.

1] Turn on the RUN switch to start operation for the 14-point type or higher. Turn this switch

off to stop operation.

For the 10-point type, turn on the RUN input terminal to start operation. Turn it off to stop

operation. 2] The start and stop operations can be performed with designated external inputs or internal

outputs by designating the operation control inputs with a programming unit. 3] Apart from the operation described above, if a malfunction is detected in the system while it

is running, operation stops and the outputs are aborted (OFF). 4] If the power is shut off and then turned back on while the system is running, operation starts.

When the power shuts off, turn off the power to the PLC, then shut off the external input

power. When turning the power back on, turn on the external input power before turning on

the power to the PLC. 5] When starting operation, do so after clearing internal information which is not designated

for storage during power failure. When stopping operation, leave the internal information as

is, turn off the outputs and then stop the operation. 6] When the power has been cut off for longer than the time allowed for the momentary power

failure, then depending on the system load status, either operation continues or the system

perceives that a power shut off has occurred and restarts operation. To resume operation

securely, have the power remain off for 1 minute or longer.

7 Operation parameters Each type of condition for operating the PLC can be set. The possible settings for operation

when an error occurs are provided below. 1] Operation may be continued when I/O information does not match. 2] Overload check time can be set. The initial value is 100 ms and the module stops when the

time for one scan takes longer than the set overload check time. (overload error) 3] Operation may be continued when an overload error occurs. 4] When a power failure (power shutoff) occurs, the internal output area for retaining

information and the timer counter range can be designated. And, the setting below is possible. 1] The name of the user program can be registered. 2] A password can be set up so that the third party cannot reference the program. 3] It is necessary to register the type of I/O module used as an I/O assignment table. In order to

create this I/O assignment table, the types of I/O modules that are connected can be read.

8 Change while in

operation

A part of a program can be modified during operation. 1] If a modification is made with a programming unit and a change is performed while in

operation, the user program in the CPU is changed and the altered program is switched

internally at the end of scanning, and operation continues with the new program. 2] When a control instruction is included in the modification to the program, make the changes

after first performing the control instruction change procedure in the programming unit to

check for safety. 3] Until operation starts to continue with the new program, a pause [halt period] occurs when

the module does not run. External input information is not being received during this time,

so leave a sufficient time for executing a change while in operation.

9 Forced set/reset Forced set and forced reset of the designated I/O can be performed from the programming unit

connected to the CPU module.

10 Forced output Output can be forced with respect to the designated I/O number from the programming unit

connected to the CPU module. For I/O that is not designated, outputs are shut off.

11 Calendar clock

function (only for 23- and 28point types)

23-point and 28-point types have the calendar clock function. 1] The year, month, date, day of the week, hour, minute and second can be set. 2] There is a function for making adjustments in 30-second units. 3] When a battery is not installed, the calendar clock information is not retained when power

goes off. The calendar clock must be reset. (The battery is an optional. Purchase separately.)

12 Dedicated port This is a communication port with dedicated protocol for the H-series. The communication

command called the task code is defined in the port. 1] A programming unit can be connected. (However, the command language programmer

PGM-CHH and the portable graph programmer PGM-GPH cannot be used.) 2] Port 1 and port 2 can be used as dedicated ports. Transmission speed, etc. can be switched

using the DIP switch. (Port 2 is supported only by the 23-point and 28-point type models.)

13 General purpose port General purpose port function is supported from software version H0130 (WRF051=H0130) or

newer. This function enables serial communication to any standard devices like bar code reader by using TRNS/RECV command in user program.

14 Modem control A modem can be used to connect externally. It becomes operable when data receives from the

external media, and task code communication can afterward be performed. Port 1 can be assigned for this function by switching the DIP switch. (The 10-point type is not supported.)

15 Self-diagnosis Self-diagnostic tests for the following items are performed:

1] Microcomputer check 2] System program area check 3] Memory check 4] User program check 5] Internal output area check 6] Mounted I/O check

16 Abnormal handling When a problem occurs, the error code that indicates the error description is output to special

internal output WRF000 as a hexadecimal value. Also, errors are notified to the external devices through the OK LED. If the error level is high, the CPU stops operation, but depending on the error, the operation may be continued using the user settings. If multiple errors occur, the error code with higher error severity is set. The detailed information is also set to the special internal output. Also, this information is always recorded in the power failure memory, so the information can be referenced even after the power is cut off. (However, a battery is required.) The clearing of the error information can be conducted by turning on R7EC.

17 Task code By combining individual task codes, the following functions can be achieved by the programs in

the host computer: 1] CPU control (RUN/STOP control of CPU, occupy/release, CPU status read, etc.) 2] I/O control (various types of monitoring) 3] Memory write (all clear, batch transfer, etc.) 4] Memory read (reading of programs, etc.) 5] Response (various responses from CPU)

18 Instruction Programming can be performed for various purposes and usage by combining Ladder and the

instruction language.

19 High-speed counter The external input of the basic unit can be used as a high-speed counter by specifying it as a

counter input. The following can be set. 1] Single-phase counter, 2 channels 2] Single-phase counter, 4 channels (For the 10-point type, it is single-phase, 3 channels.) 3] Two-phase counter 1 channel, single-phase counter 1 channel (For the 10-point type, it is

two-phase, 1 channel.) The functions include a count operation (up/down, leading/trailing), coincidence output control, preset by preloaded input, and count value reading by strobe input.

case, pulses are output at the specified frequency with a duty between 0 and 100 %. A maximum of 4 points, including the pulse array output, can be set.

22 Pulse train output The external output of the basic unit can be specified for pulse output. In this case, pulses are

output at the specified frequency with a duty between 30 and 70 %. A maximum of four points, including the pulse output, can be set.

23 Analogue input The analogue input function is available in the 23-point type and analog exp. unit. The

resolution is 12 bits and it can be used by either selecting a current input between 0 and 20 mA or a voltage input between 0 and 10 V.

24 Analogue output The analogue output function is available in the 23-point type and analog exp. unit. The

resolution is 12 bits and it can be used by either selecting a current output between 0 and 20 mA or a voltage output between 0 and 10 V.

25 Potentiometer 14-point, 23-point, and 28-point types have two potentiometers, with which setting values etc.

can be changed without using the programming units.

26 Battery A dedicated battery can be installed in the 23-point and 28-point types so that data in the data

memory can be maintained even when the power supply to the main unit is shut off. In addition, the data of the calendar clock in the 23-point and 28-poins types can be maintained. The battery is an optional (model EH-MBAT). Please refer to Chapter 15 (4) Life of the battery.

Note: There are functions supported by H series that are not supported by this PLC (debug, trace, force, and simulation functions).

5.2 List of Instructions

[Legend] Condition codes

DER Data error (special internal output R7F4)

Set to “1” as a data error when the I/O number is exceeded or when the BCD was abnormal data, etc. When there is no data error, it is set to “0.”

ERR Error (special internal output R7F3)

Set to “1” when an error is generated when a control instruction and a special instruction are executed. The error code is set in WRF015. When there are no errors, the previous status is maintained.

SD Shift data (special internal output R7F2)

Performs shift-in of the contents of SD by the SHR or SHL instruction.

V Over flow (special internal output R7F1)

Indicates that a digit overflow has occurred and the signed data range is exceeded as a result of signed data operations.

C Carry (special internal output R7F0)

Indicates the contents of digit increase due to addition, digit decrease due to subtraction, and shift-out due to shifting.

z Maintains the previous status. 1] Set to “1” when there is an error in operation results. The previous status is maintained if there is no

error.

↕

Changes according to the operation result.

Processing time This indicates the instruction processing time.

The displayed value is an average. It varies depending on the parameter and data count with the instructions used. See the details on the instruction specifications for details.

Function

• For the UP counter, increments the progress value by 1 each time the leading edge of the startup condition is detected, while

it decrements the progress value by 1 for the DOWN counter. The coil switches on when the progress value is greater than or equal to the set value and switches off when the progress value is less than the set value. When the counter clear CL n switches on, the progress value is cleared to 0 and the coil switches off.

• The progress value is set in TC n, and the value will be in the range of 0 to 65535 (decimal).

• If the progress value is updated during RUN, the operation will be performed using the new progress value at that point.

• If an I/O is set for the set value, the set value can be changed during operation by changing the I/O value, since the set values

are updated during each scan.

Notes

• A maximum of 256 points can be used for the timers and counters TD, SS, CU, CTU and CTD in total.

• The timer numbers and counter numbers cannot be overlapped.

• The numbers for the UP coil and DOWN coil must be the same.

• While the counter clear CL n is on, the rise of startup condition is ignored.

• Since the startup condition of the counter is edge detection, the condition for one scan may not be detected during the first

scan after RUN starts.

• If the set value is set to “0”, it is regarded as a coil that is always on and controlled by the CL n.
