Serial and Ethernet Communication

HMIGXU3512 provides two independent serial communication interfaces. COM1 uses RS232C through a 9-way male SUB-D connector, while COM2 supports RS422/RS485 through a second 9-way male SUB-D connector. An integrated 10/100BASE-TX Ethernet interface provides network communication, with USB type A and mini B interfaces available for supported peripheral and service connections.

The communication configuration must match the connected controller interface, physical layer, and cable arrangement. RS422/RS485 wiring should maintain the specified signal pair arrangement and appropriate shield termination. Ethernet cabling should be routed separately from high-energy power conductors where practical.

Frequently Asked Questions

Q: What supply voltage is specified for HMIGXU3512?
A: The rated supply voltage is 24 VDC.

Q: What serial interfaces are provided?
A: COM1 provides RS232C through a 9-way male SUB-D connector. COM2 provides RS422/RS485 through a 9-way male SUB-D connector.

Q: What display resolution does the panel provide?
A: The 7 inch LCD touch screen provides 800 x 480 pixels WVGA resolution with 65536 colours.

Field Installation Guidelines

Install the panel in a mounting cut-out of 190 x 135 mm and ensure that the front-panel sealing surface is clean and free from mechanical damage. The specified IP65 protection applies to the front panel.

Connect the 24 VDC supply with correct polarity and suitable industrial protection. Route serial communication wiring away from high-current switching conductors. For RS422/RS485 connections, maintain the required differential signal pair arrangement and apply cable shielding according to the installation grounding scheme.

Use suitable Ethernet cabling for the 10/100BASE-TX interface. Avoid routing communication cables parallel to high-voltage or high-frequency drive wiring over long distances. Verify connector seating and cable strain relief before commissioning.

HMIGXU3512 was discontinued on May 1, 2024. Schneider Electric identifies HMIET6400 as the recommended replacement. Interface assignments, software compatibility, mechanical dimensions, and application configuration should be checked before replacement.
