The processing instructions, application instructions, control instructions, transfer instruction and fun instructions can be described in a processing box.
Chapter 7 Programming 7.4 Program Transfer The MICRO-EH stores the user programs written from the peripheral units in the execution memory (RAM). Then, it transfers the user programs to the FLASH memory (backup memory) utilizing the idle time of the MPU in the internal area of the MICRO-EH. This is performed regardless of operation status of the CPU.
Chapter 7 Programming Note 1) The following lists the special internal outputs for various settings that can be transferred to the backup memory by the Memory Request for Various Settings Flag (R7F6). 1 Table 7.5 List of special internal outputs that can be stored Special internal output Function that can be stored WRF01A Dedicated port 1 Communication settings 2 WRF03C Dedicated port 1 Modem timeout time 3 WRF03D Dedicated port 2 Communication settings No.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O The MICRO-EH operates in four operation modes. By selecting the proper operation mode, input/output points can be assigned to the counter input, interrupt input, pulse output, and PWM output functions, instead of the normal input/output function. The 14-point type model or higher are equipped with two potentiometers.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.1.2 Operation Mode Select one mode from the 5 modes shown in Table 8.1 (mode 10 described in following pages.) and set the mode number in the special internal output WRF070 when the CPU is in STOP status. *1: *2: If parameter in WRF070 is not saved by R7F6, the value will be 0 at the next power on. The operation mode setting can be changed only when CPU is in STOP status.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.1.3 Input/Output Setting Configure each I/O setting in the special internal output (WRF071) and make it effective by setting R7F5 ON in CPU STOP status. This information is normally reset at every power on, but this can be saved in the FLASH memory by setting R7F5 ON after that.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.1.4 Input/Output Setting (Mode 10) Mode 10 had been added since Ver. 01.13. I/O assignment of mode 10 is very flexible as follows. Parameter setting is compatible with existing mode 0 to 3 except for WRF071. Operation of FUN command (FUN 140 150) is same for all the mode 0 to 10. Outline Input and output are configured in every group as below.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.1.5 Special Output Operation in CPU STOP Status Generally the counter output, PWM output and pulse output are not generated if the CPU is in the STOP state. To output these outputs when the CPU is in the STOP state, turn on the special internal output R7DC.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.2 High-Speed Counter (Single-Phase) The high-speed counter settings are stored in the special internal outputs (WRF070 to 7E). It is only possible to perform the setting through the special internal output (WRF071) when the CPU is stopped and the output is turned off.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O Others 7] The user program can switch from using a counter as an up counter to a down counter, as well as from a down counter to an up counter while the counter is operating (using FUN142). * The counter output does not turn on unless the control output flag (R7FC to R7FF) is turned on. (2) Preload input operation When a preload signal is entered, the current counter value is reset to the preload value.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.2.2 Setting of Single-Phase Counter If either one of operation modes 1, 2, or 3 is selected, the single-phase counter should be set using the special internal output (WRF072 to WRF07E). In order to make the contents of the various settings valid, it is necessary to turn on the special internal output R7F5. The settings can be changed using the FUN instruction during the CPU operation (some settings cannot be changed, however.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O (4) Setting the counter preload When preloading is used, the value to be preloaded should be set for each counter used. Any value in the range from 0 to FFFFH (0 to 65,535) can be set. WRF07A: Preload value for counter 1 WRF07B: Preload value for counter 2 WRF07C: Preload value for counter 3 WRF07D: Preload value for counter 4 Figure 8.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.3 High-Speed Counter (Two-Phase Counter) When operation mode 3 is selected, two-phase counters can be used. Four kinds of phase counting modes are available for two-phase counters. The settings of the two-phase counters are stored in the special internal outputs (WRF06F to 72, 76, 7A, and 7E).
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O (2) Phase counting mode 1 In this mode the counter counts at the rising edge of input 1A. At this point, if input 1B is 0 (Low) it counts up, and if input 1B is 1 (High) it counts down. Input 1A Input 1B Count value Off preset On preset Coincidence output Figure 8.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O (4) Phase counting mode 3 In this mode the counter counts at the rising and falling edge of input 1B. It counts up when input 1A is more ahead of input 1B, and down when input 1A is lagging behind input 1B. Input 1A Input 1B Count value Off preset On preset Coincidence output Figure 8.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.3.2 Setting of Two-Phase Counter The setting of the two-phase counters are stored in the special internal outputs (WRF072 to WRF07E). (1) Phase counting mode Set the phase counting mode (0-3) in WRF06E. Please see the chapter 8.3.1 about phase counting mode. WRF06F: Phase counting mode Figure 8.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O (5) Individual counter setting The on-preset and off-preset values can be changed for each two-phase counter by the special internal output for individual setting (WRF058) regardless of whether the CPU is operating or stopped. Turn on the corresponding bit in the following special internal outputs when only the on-preset or the off-preset value should be changed for a two-phase counter.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.4 PWM Output A PWM output can be set as an output by setting the operation mode and output terminal. By setting an output to a PWM output, a pulse with a duty ratio in the range that corresponds to the specified frequency can be output. 8.4.1 Operation of PWM Output The PWM output settings are stored in the special internal outputs.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.4.2 Setting the PWM Output The settings of the PWM output operation are stored in the special internal outputs (WRF072 to WRF079). (1) Setting the PWM output frequency Set the frequency of output pulse for each PWM output to be used in special internal outputs. The setting values must be 10 to 2000 (HA to H7D0). If the frequency value is set to less than 10 Hz, it is changed to 10 Hz by the system.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O (3) Effective range of PWM output on-duty values When correcting on-duty values by setting the value that corresponds to the CPU model in the special internal output (WRF06B) for setting PWM/pulse output correction, the effective range of the on-duty values differs depending on the frequency and CPU model to be used. The effective range of the on-duty values is calculated from the following expressions.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.5 Pulse Train Output A pulse output can be assigned to an output by setting an output terminal. By setting an output to pulse output, a specified number of consecutive pulses with a duty ratio of 30 to 70 % can be output. ((To output a pulse having a duty ratio of 50 %, set the value corresponding to the CPU model in the special internal output WRF06B, by referring to Section 8.1.4.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O To change the number of output pulses, the following operation will be performed: 1] When the number of pulses is to be changed to a value larger than the number of pulses currently being output, pulses will be output until the number of newly changed pulses is reached, and then the pulse output stops.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O (4) At setting abnormality If the sum of the frequencies of the pulse outputs is set to exceed 5 k when the PI/O function setting flag (R7F5) is turned on, the bit for the total pulse frequency abnormality in the error display special internal output turns on, and none of the pulse outputs are output.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.6 Interrupt Input When either operation mode 0, 1, or 3 is selected, it is possible to assign an interrupt input to X1, X3, X5, and X7 by the special internal output (WRF07F). (The 10-point type CPU does not have X7.) It is only possible to set them by the special internal output under the conditions where the CPU is stopped and the output is off.
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.8 Potentiometers CPUs other than of the 10-point type are equipped with two potentiometers. Through the use of these potentiometers, it becomes possible to change values in the special internal outputs from the outside using a tool that looks like a screwdriver. The resolution is 10 bits, so it is possible to adjust the values from 0 to 3FFH (1 to 1,023).
Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O 8.9 Analogue Input The 23-point type CPU is equipped with two points of analogue input. The input to these two points can be set to voltage input or current input individually. The setting of current or voltage input is made in the special internal output WRF06E. This special internal output is stored in the FLASH memory by turning on various setting write requests (R7F6).

Chapter 9 PLC Operation Chapter 9 PLC Operation The operating status and stop status of the MICRO-EH can be switched through various types of operations. This feature is shown in Figure 9.1. Cancel operation definition input Switch “RUN” and operation definition input “ON” Switch “RUN” Stop status Operating status Switch “STOP” Stop status Switch “STOP” or operation definition input “OFF” Designate operation definition input Caution The MICRO-EH cannot handle a REMOTE specification.
Chapter 9 PLC Operation 9.1 RUN Start When the MICRO-EH switches to the operating state, the user program is executed in sequence from the beginning. The user programs consist of a normal scan program and periodical scan program. In addition to these programs, there is a subroutine area defined as a subroutine. No. 1 2 Program classification Normal scan program Periodical scan program Table 9.2 Program classification Description Expression This is the program that is normally executed.
Chapter 9 PLC Operation Each program is executed in the order of the priority shown in Figure 9.2. Each program is executed while monitoring the execution time of each program area. If the monitored time exceeds the specified time, this causes a congestion error and operation stops. When continued operation has been specified, operation continues. The timing for scan execution is shown in Figure 9.2. System processing is performed at set periods (every 5 ms), followed by communication system processing.
Chapter 9 PLC Operation (2) Causes of congestion errors at normal scan Congestion errors may occur at normal scan because of the following three possible reasons. In particular when using a periodical scan program and an interrupt scan program together, care must be taken to create the program in such a way that the total scan time does not exceed the congestion check time.
Chapter 9 PLC Operation 9.1.2 Periodical Scan (1) Definition and operation This scan executes interrupt programs (periodical scan programs) while the CPU is operating with a fixed cycle time (10 ms, 20 ms, or 40 ms) specified by the users. Enter the periodical scan program to be executed between instructions INT0 and RT1 if it should be started up with a 10 ms cycle time, and between INT1 and RT1 if it should be started up with a 20 ms cycle time.
Chapter 9 PLC Operation (3) Continuation of operation after a congestion error If a congestion error occurs when the special internal output bit R7C1, which specifies whether the operation should continue after a congestion error, is turned on, the execution of the periodical scan is stopped and the periodical scan is executed from the beginning again. If the operation continuation specification for the normal scan is Off when this happens, the scan stops as a congestion error at a normal scan.
Chapter 9 PLC Operation (3) Continuation of operation after a congestion error occurred If an interrupt scan congestion error occurs when the special internal output bit R7C2, which specifies whether the operation should continue after a congestion error, is turned on, the interrupt scan is started anew and the scan is executed from the beginning again.
Chapter 9 PLC Operation 9.1.4 Relationship of Each Scan Type When three types of scan occur at the same time, scan is executed in the order of periodical scan, then interrupt scan, and then normal scan.
Chapter 9 PLC Operation 9.2 Online Change in RUN The user programs can be modified during operation while retaining the output status as is. This is called the “program change while running” function. To modify the user programs, special programming software or programmer is required. Refer to the individual manuals on the operation. Program change while running cannot be executed in the following situations. Perform this operation after satisfying the conditions. Table 9.
