HDPM6000 HMI Configuration

[Stuart_Cheng]

Hi All,

I’m currently working on HDPM6000 and have a couple of questions regarding its communication setup with the HMI:

1. he HDPM6000 head unit is connected to the HMI via RS485. According to the manual, the baud rate is set to 15200. Is this baud rate fixed, or is it adjustable? I tried accessing the HMI system settings, but the "COM Port" button is not available.
   

2. We’re considering switching from RS485 to Ethernet communication. Is it possible to configure ETH1 to operate in "HMI mode", and then connect it directly to the HMI with an Ethernet cable?

Any insights with this setup would be greatly appreciated. Thanks.

Hi @Stuart_Cheng 

1- The Baud Rate for the RS485 communication between the HDPM6000 head unit and the HMI display is generally fixed at 115200 baud, since HMI continuously polls the head unit for a large amount of data.
Also, the default serial port settings for the HDPM6000 head unit is:
Unit ID: 1, Parity: None, Stop Bits: 2, Baud Rate: 115200

The non-adjustable baud rate setting on the HMI ensures plug-and-play functionality and a faster data update rate for the HDPM6000 system components.

2- For the 4.7" and 7" HMIs, the devices currently use only the serial communication port, while the Ethernet port is inactive and may be enabled in the future.

Only the 10" Ethernet-based HMIs can communicate via the Ethernet port connected to the second Ethernet port (ETH1) on the head unit. In this case, the meter number (1–4) must be configured through the head unit’s web interface to display parameters on the HMI, as each HMI can poll up to four head units.

Hi @Mehran_Mehrnia,

Thanks for the clarification. It is much clearer.

One thing I am not sure about is the 10" HMI. I did not see this option in our catalog. Or does it just refer to other 3rd party HMI? Thank you.

Hi @Stuart_Cheng 

You're welcome. 

The 10" HMI is not commercialized, its application was developed specifically for a custom project and is not as general-purpose as other types of HMIs.
