ASEM HMI30 Wiring Instructions

1. Power Supply Wiring

Equipped with rear industrial round power connector, supporting 18–36 VDC wide-range input (rated 24 VDC standard operation).

Pin definition: DC 24V positive, DC 0V negative, PE protective earth terminal.

Wiring requirements: Strictly distinguish positive and negative poles. Built-in reverse polarity and over-voltage protection prevents accidental power damage.

The PE protective earth must be firmly connected to the cabinet grounding bar; PE is isolated from signal ground and cannot be connected mutually.

Optional Micro-UPS supercapacitor module provides 500ms power hold-up time to ensure data saving during instantaneous power failure, supporting plug-and-play installation without additional wiring.

Recommended wire gauge: 0.75–1.5 mm² shielded power cable.

2. Ethernet Wiring (LAN1 / LAN2, RJ45 Interface)

LAN1: Main industrial network port, supports IEEE1588 precise time synchronization, connected to PLC and DCS system switches.

LAN2: Independent dedicated port for ASEM Ubiquity remote diagnosis and maintenance services, connected to remote access network.

Cable standard: Industrial CAT5e / CAT6 shielded twisted-pair cable.

Wiring note: The two Ethernet ports operate independently without built-in bridging. Avoid arbitrary interconnection of LAN1 and LAN2 through external switches without network planning.

3. Serial Port COM1 (DB15 Male Interface)

Software-selectable communication modes: RS232, RS422, RS485 and Siemens MPI; hardware wiring must match the software configuration mode.

RS232 Point-to-Point Wiring

HMI TX ↔ PLC RXD

HMI RX ↔ PLC TXD

HMI GND ↔ PLC Signal GND

RTS/CTS hardware handshake is only required for specific scenarios; keep unconnected for conventional Modbus-RTU communication.

RS485 Two-Wire Multi-Drop Wiring (Modbus-RTU / Siemens MPI)

HMI Data+ ↔ PLC A / D+

HMI Data- ↔ PLC B / D-

Connect signal ground between HMI and all slave devices uniformly.

Install 120 Ω terminal resistors at both ends of the bus; adopt daisy-chain topology and prohibit star branch wiring.

Supports Siemens MPI protocol with maximum baud rate of 187.5 kbit/s.

RS422 Four-Wire Full-Duplex Wiring

HMI TX+ ↔ Remote Device RX+

HMI TX- ↔ Remote Device RX-

HMI RX+ ↔ Remote Device TX+

HMI RX- ↔ Remote Device TX-

Implement common signal ground connection for all devices.

4. USB Interfaces (USB1 / USB2, Rear Type-A Host)

Used for connecting peripheral devices such as USB mouse and keyboard, and supporting program downloading and log export via U disk.

Single-port maximum output current: 500 mA; high-power USB devices are prohibited.

Plug-and-play design with no additional wiring required.

5. SD/SDHC Card Slot

Rear push-pull card slot, no wiring needed.

Applied for program recovery, recipe backup and alarm log storage, compatible with SD/SDHC cards up to 32GB.

6. Grounding and EMC Installation Specifications

The front-panel IP66 protection level is only valid with standard panel installation and intact sealing gaskets.

Signal cables adopt single-end grounding at the cabinet grounding bar; double-end grounding is forbidden to avoid ground loop interference.

Keep power cables and signal cables separated with a spacing of no less than 20 mm to reduce electromagnetic interference.

Reliable PE grounding is mandatory; floating grounding installation is prohibited.

7. General Wiring Precautions

Complete all wiring work before powering on the device; hot plugging of DB15 serial port is forbidden during operation.

The serial communication mode is software-defined; mismatched wiring and configuration will cause communication failure.

Strictly follow official cutting size for panel installation; protect the gasket to ensure IP66 protection performance.

USB and SD card interfaces support hot swapping; power supply and serial ports do not support hot plugging.

8. Typical Application Wiring Topology

Standard automatic system: LAN1 connects to PLC switch, COM1 RS485 connects to Modbus-RTU field equipment, LAN2 is reserved for Ubiquity remote access.

Siemens MPI communication: Use dedicated DB15-MPI cable to directly connect S7-300/400 series PLC, and set 187.5 kbit/s baud rate in the HMI project software.
