This outlines the cMT Web HMI’s key hardware features, including Ethernet connectivity, power requirements, battery usage, and its ability to interface with web-based industrial systems.
Ethernet Ports
The cMT Web HMI provides two Ethernet ports. LAN1 supports 10/100/1000Mbps, while
LAN2 supports 10/100Mbps. The indicators are as follows:
- Orange LED: Indicates LAN connection status.
- Green LED: Indicates active communication status.
For Ethernet connections, please use a CAT-5e network cable.
CR2032 Battery
The cMT Web HMI requires a CR2032 lithium battery to keep the RTC running.
Battery specification: CR2032 3V lithium battery.
Power Connection
The cMT Web HMI is only DC powered. The specified DC voltage range is 24±20 volts,
ensuring compatibility with most controller DC power systems. The power conditioning
circuitry inside the unit is managed by a switching power supply, and the peak starting
current can reach up to 2A.
Note: Connect positive DC line to the ‘+’ terminal and the DC ground to the ‘-‘
terminal.
Operating Environment
- Built-in web client program: Google Chromium Version 132.
- Supports connection to web servers, web-based SCADA systems, PLCs, and HMIs.
- Using A Maple Systems HMI as an example, it allows the use of EasyAccess 2.0 for editing HMI interface settings and WebView for monitoring HMI screens through a web browser.
