TOSHIBA V200 series programmable logic controller

Software Configuration and Programming

4.1 OIL DS software installation

System requirements:

Operating systems Windows 2000 (SP4), XP (SP2), Vista

Processor ≥ 800MHz (Vista requires ≥ 1GHz)

Memory ≥ 256MB (Vista requires ≥ 1GB)

Hard disk space of 800MB (including 200MB. NET Framework)

Display resolution 1024 × 768 (16 bit high color)

Installation steps:

Run Setup. exe and select the installation path (default C: Program Files OIL DS).

Wait for the installation to complete and start the software through "Start → Program → OIL DS".

When uninstalling, execute through "Start → Program → OIL DS → Uninstall OIL DS".

4.2 Ladder diagram programming

Core process:

New project: Select V200 model (such as GPU288 * 3S), configure project name and storage path.

Define Tag Database: Assign I/O addresses (such as X0000 corresponding to digital input 1) and register types (input X/output Y/configuration MW).

Edit ladder diagram: Drag and drop "normally open contact (NO)", "coil", "function block (such as MOV-W)" to construct logic, supporting subroutines and interrupt programs.

Compile and Download: Press F9 to compile (if there are no errors, it will display "Compilation Successful"), and download it to the PLC via USB/RS485.

Program type:

Main program: It runs in a loop during normal operation and needs to end with the "END" instruction.

Subroutine: Called with the "CALL" instruction and returned with the "RET" instruction.

Interrupt program: Timer interrupt (5-1000ms), I/O interrupt (triggered by high-speed counting), must end with the "IRET" instruction.

Detailed explanation of special I/O functions

5.1 High speed counter

Function type:

Type Input Channel Maximum Frequency Counting Range Application Scenarios

Single phase counter 2-channel (X000/X001) 50kHz 0~4294967295 (32-bit) pulse counting (such as encoder)

Single phase speed counter 2-channel (X000/X001) 50kHz 0~4294967295 (32-bit) speed measurement (fixed sampling time)

Orthogonal biphasic counter 1 channel (X000=phase A, X001=phase B) 5kHz 0~4294967295 (32-bit) bidirectional counting (such as motor forward and reverse rotation)

Configuration register: Select the function mode through MW10 (high-speed input configuration register), such as "MW10=0x0010" to enable the single-phase counter.

5.2 Pulse/PWM output

Pulse output:

Channel: 1 channel (Y0=CW/PLS, Y1=CW/DIR).

Frequency range: 50~5000Hz, supports positive and negative frequencies (corresponding to positive and negative reversals).

Configuration: Set MW11 (pulse output configuration register) to "0x0001" enabled, and set the frequency for MW22/MW23.

PWM output:

Channel: 1 channel (Y0).

Parameters: frequency 50~5000Hz, duty cycle 0~100% (1% step size).

Configuration: MW11 is set to "0x0000" enabled, and MW24/MW25 is set to duty cycle.

5.3 Interrupt Input

Channel: 2 channels (X001=Interrupt 1, X002=Interrupt 2).

Trigger method: Rising edge (OFF → ON) or falling edge (ON → OFF), configured through MW10's Bit4/Bit5.

Response time: Interrupt signal ON/OFF pulse width ≥ 100 μ s, ensuring stable recognition of PLC.

Troubleshooting and Maintenance

6.1 Troubleshooting process

Power failure (PWR light not on):

Check the power wiring: whether the terminals are loose and whether the voltage is 24VDC ± 15%.

Remove the expansion module: If the PWR light is restored, troubleshoot the expansion module.

Check internal power supply: If it still doesn't light up, replace the PLC host.

CPU malfunction (RUN light not on):

Check the mode switch: whether it is in the "RUN" position, switch to "RUN" and retry.

Check the ERR light: If the ERR light is on, read the fault code through OIL DS (such as "WDT Error" indicating watchdog timeout).

Re download firmware: If the RUN/ERR lights flash simultaneously, the firmware is damaged and needs to be re downloaded.

Input/output fault (abnormal I/O status):

Check the wiring: Check if the terminal screws are loose and if the wires are damaged.

Monitoring I/O status: Check the X/Y status through the "Monitor" function of OIL DS to determine whether it is a hardware or program issue.

Replace module: If one of the I/O channels is consistently abnormal, replace the corresponding expansion module.

6.2 Maintenance Standards

Daily inspection (daily):

Appearance: The LED status is normal (PWR is constantly on, flashing when RUN is running), and there is no abnormal sound/odor.

Environment: Temperature 0~55 ℃, humidity 20%~90%, no dust accumulation.

Regular inspection (every 6 months):

Cleaning: Use compressed air (≤ 0.3MPa) to clean the dust from the cooling fins and ventilation openings.

Wiring: Tighten all terminal screws (to the specified torque) and check the insulation layer of the wire.

Insulation test: After power failure, use a 500V megohmmeter to test the insulation resistance of the main circuit to ground to be ≥ 1M Ω.
