Textile Finishing with an Integrated HMI/PLC: Coolmay Case
Supplier-reported machine application; end customer unnamed. Location not stated by supplier.
Project attribution: the work described below is reported by Coolmay and its project partners. ProSense is providing application commentary and does not claim to have delivered this installation.
The documented project
Coolmay publishes a textile-finishing application using an integrated touchscreen controller to manage configurable process sequences. The supplier identifies a QM3G-70FH-44MT-1AD-K controller, with EX3G-70C-44MT-1AD-K shown as an alternative designation, and a CM6024 power supply.

Applying the idea to a new project
For a similar machine, write the operating sequence before choosing I/O. Separate recipe parameters from maintenance settings and define who may change each. Document the transition from one step to the next, including timeout, pause, restart and recovery after an interrupted cycle.
Equipment and integration questions
Prepare an I/O schedule showing sensor type, signal level, actuator interface, analogue channels and communications. Check the precise controller revision and software requirements against the proposed program. Model designations in an overseas case should be verified against the part offered locally.
What to verify before handover
Commission recipes with representative materials and retain program backups and version details. Test the response to a disconnected sensor and an interrupted cycle. Machine guarding, interlocks and emergency stopping need a separately assessed safety design; ordinary sequence logic is not evidence of a safety rating.
