H0U Series PLC User Manual
Thank you for purchasing the H0U series programmable logic controller (PLC) independently developed by
Inovance Control Technology Co., Ltd. Read the manual carefully to be familiar with the product features
and be able to use the product safely.
This manual describes the specication, features and usage of the H0U series PLC. For the developing
environment and design method of user programs, see the H0U Series PLC Programming Manual and the
H1U/H2U Series PLC Instruction & Programming Manual issued by Inovance.
The H0U series PLC has the following features:
◆It integrates PLC and TOD programs and allows programming of control logics & display interface.
◆It supports all the instructions of the H1U and the CAN communication protocol.
◆It reaches the user memory space of 8k steps and the maximum capacity of the user TOD programs of
56 KB.
◆It has two independent communication ports (COM1, COM2), making it act as master or slave.
◆It supports 6-channel high-speed inputs and 2-channel high-speed outputs (only transistor output).
◆It supports display in both simplied Chinese and English, and switchover between the two languages
online.
◆It has a total of 25 functional keys, whose functions can be dened freely.
◆It allows you to download the PLC and TOD programs via AutoShop and HTodEditor.
Safety Information and Precautions
DANGER
◆Provide a safety circuit outside the PLC in the application so that the control system can still work safely
even if external power failure or PLC fault occurs. Take the following aspects into considerations in the
design:
◆In the external circuit of the PLC, an emergency stop circuit, a protection circuit, an interlock circuit
of forward/reverse rotation operation, and position upper/lower limit interlock circuit are necessary to
prevent equipment damage
◆To ensure safe running of the equipment, external protection circuit and safety mechanism must be
designed for the output signals that may cause serious accidents.
◆When the CPU of the PLC detects an abnormality of its own system, all outputs may be cut off. When
a failure occurs on the controller circuit, related outputs may be out of control. Thus, an appropriate
external circuit must be designed to ensure normal running of the equipment.
◆When the output units such as relay or transistor are damaged, related outputs will be out of control
and be continuously kept ON or OFF. Return the AC drive with damaged output unit to Inovance for
repair.
◆The PLC is designed for indoor electric environment. A lightning protection device must be installed for
the power supply system, so that lightening overvoltage is not applied on terminals of the PLC, avoiding
damage to the equipment.
■During Installation
WARNING
◆Install the PLC in places free from dust, oil smoke, conducting dust, corrosive gas, combustible gas,
high temperature, condensation, wind & rain, vibration and shock. In addition, electric shock, fire,
malfunction may also cause damage and deterioration to the equipment.
◆During screw hole processing and wiring, ensure that no metal filing and cable end falls into the
ventilation hole of the controller, because such stuff may causes a re, fault, or malfunction.
◆After installation of the newly purchased PLC is complete, ensure that there is no foreign stuff on the
surface of ventilation. Failure to comply may result in poor cooling effect during running, which may
lead to a re, fault or malfunction.
◆The installation and wiring must be secure and reliable. Poor contact may cause malfunction.
■In Design

■At Wiring
DANGER
◆Ensure that all power supplies are cut off before installation or wiring.
◆During screw hole processing and wiring, ensure that no metal lings or cable end drops into ventilation
holes of the controller. Failure to comply may result in a re, fault or malfunction.
◆Perform wiring or plug/remove the cable connector only after power-off. Failure to comply may result in
electric shock or damage to the circuit.
WARNING
◆Don’t provide external power supply to terminal 24+ of the main unit or expansion unit.
◆Use shielded cables for high-frequency signal input/output in applications with severe interference to
enhance anti-interference capacity of the system.
■During Running and Maintenance
DANGER
◆Connection or removal of the communication cable, cables of the extension card and cables of the
control unit can be performed only after power-off. Failure to comply may result in damage to the
equipment or malfunction.
◆The operations such as online modication, forcible output, RUN and STOP can be performed only
after you read the manual and guarantee safety.
WARNING
◆Treat scrapped PLC as ordinary industrial waste.

■Communication Ports
The H0U series PLC has four communication ports as standard configuration. COM0, COM1 and
COM2 are standard RS485 communication interfaces. COM0 is used for user program downloading,
commissioning and monitoring. COM1 and COM2 are free interfaces and support the Modbus protocol, N:N
protocol, parallel protocol, HMI protocol, PC link protocol, RS instruction and Modbus instruction. The other
one is USB interface, which has the same function as COM0.
■Power Supply Specication
The H0U series PLC adopts the DC/DC power supply.
The input voltage of the DC/DC power supply is 24 V. The outputs are +5V/+24VDD/GND and +5V/COM
respectively. +5V/+24VDD/GND provides power supply to the digital circuits and relays of the H0U, while
+5V/COM provides power supply to transistor in the mixed output.
The DC/DC power supply adopts self-excitation to generate pulse width modulation (PWM) square wave
and uses TL431 for feedback. The power supply voltage of the main circuit is +5V/GND.
The following table describes the power supply specication of the H0U series PLC

■Input Specication
For the X terminals, the rated input voltage is 24 VDC. Relative to COM (0V), the X terminals is OFF when
the input voltage is below 4.0 V, is ON when the input voltage is above 15.0 V and is not xed when the
input voltage is 4.0–15.0 V. On the condition of rated input voltage of 24 VDC, the input current is 4–6 mA.
