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 specification, 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 simplified Chinese and English, and switchover between
the two languages online.
It has a total of 25 functional keys, whose functions can be defined freely.
It allows you to download the PLC and TOD programs via AutoShop and HTodEditor.
Safety Information and Precautions
In Design
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

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.
