HM Series Connection Manual
3. Preface
Thank you for using this product. This manual will provide the instruction of
communication between HM series Human-machine Interface (HMI) and linked
devices. “Register & Contact Numbering Range” listed in this document is just the
maximum value that the software allows. Please don’t exceed the limitation of the
linked devices themselves in practice; otherwise, it might cause communication
failure. Please read this handbook carefully before you use the product to ensure
the correctness and safety in use. Besides, put the handbook at a noticeable location
so as to make reference more convenient. Before reading through this manual,
please be sure to follow the proceedings as below:
1. Please wire according to the wiring diagram.
2. Grounding must be done for sure.
3. Please do NOT dismount HMI or make any change to the wiring when HMI is
electrified.
4. Please do NOT touch the power terminal when HMI is electrified and operating
to avoid electric shock.
If you still have question when using the product, please contact our sales staff.
Because the “Numbering Range of Registers and Contacts” might change when
PLC manufacturers launch new models, the contents of this manual need modifying
from time to time. Besides, it is difficult to update the information listed in this
handbook with the increase of communication modules. If you need the up-to-date
documents, please contact our staff or download from our Web site
