Industry Applications
Light Industry & Packaging Machinery
Perfect for tight electrical cabinets in food packaging lines and
plastic product forming machines. Controls filling, sealing, and
labeling processes with expandable I/O points (up to 176) for
additional functions like date stamping or quality inspection.
Automotive Parts Manufacturing
Reliable choice for component assembly and testing in auto parts
factories. Controls robotic arms for welding, conveyor belt
synchronization, and precision testing of automotive sensors with
high anti-interference capability.
Petrochemical & Chemical Processing
Used in refineries and chemical plants for process control, valve
regulation, and monitoring pressure/temperature in reaction
vessels. Isolated I/O design prevents signal interference in
corrosive environments.
Frequently Asked Questions
Q: After wiring and powering on, the PLC power light is on but
expansion modules don't respond—is it a compatibility issue?
A: Check firmware consistency between controller and expansion
modules, and verify connection sequence: Controller → Power Module
→ Expansion Modules. Ensure expansion cables are properly connected
and check for bent module pins.
Q: Can find the PLC via Ethernet but connection fails—what to do
with separated industrial networks?
A: Ensure computer IP is on same subnet as PLC. Check firewall
ports (TCP 502 and 102). For CPUE05 models, switch from default
serial communication to Ethernet mode in software.
Q: Connected Pt100 temperature sensor but PLC shows erratic
values—is the sensor broken?
A: Verify correct wiring for 2/3-wire type, configure software
parameters for correct sensor type and temperature range, and use
shielded cables to prevent signal interference.
Q: PLC restarts suddenly during operation, especially when motors
start—power voltage seems normal?
A: Motors cause voltage dips when starting. Use independent
regulated power supply for PLC, add EMI filter, and ensure adequate
power module capacity for expansion modules.
Q: How to protect PLC from dust and high temperature in harsh
environments?
A: Install filtered dust cover, maintain cabinet ventilation with
cooling fans, and use anti-rust agents on terminals. Choose modules
with IP20+ protection rating for durability.
