Hi,

I received this module without any documentation. I managed to open it in an attempt to identify a brand name or serial number, but unfortunately, I was unsuccessful.
As a result, my project involves replacing this module with a previous project on a Raspberry Pi. I noticed a micro SD slot. Can I run Raspbian or Linux on it? And how can I identify the GPIO pins if there are any?

Thank you in advanced

 

It appears to me it may be some kind of custom made unit, some of the items it is constructed from appear to be very similar to Weidmuller components.
I suspect that if this was a commercially manufactured unit, there would be a manuf. logo somewhere !?

 

Can you tell what chip it is? If your project is written in Raspian then you'll need a RP2040 device? I agree it looks like a custom job with even coax connections.

 

Got any more pictures of any labels. Just looking at it it kind of looks like maybe a Beckhoff module. If it is Beckhoff than its a windows machine. There are a bunch that look similar though. More pictures would be helpful.

 

What do you see if you power it up with a monitor connected to the HDMI output?

 

I think they removed the marking on the main chip, right? As
MaxHeadRoom already has said, it is most probably a customized board. At least you need to figure out the main processor. Otherwise, redesigning the whole device with the Raspberry Pi will be your last resort I think...

 

A PLC without a brand and model number is not likely to provide the option of programming it. Without a program the PLC is not very useful.
In addition, most PLC systems use their own scheme to communicate with the I/O section. So you are faced with unknowns in several aspects.
So I suggest that it will take much less time and effort and expense to replace the entire mess with a similar sized PLC system. Automation Direct provides programming software at no additional cost, so I recommend that as a source.

Consider that we have no clue as to what the program will be required to do, it may be the source of great pain. So replacement and then getting a list of what it must do will be required.

 

The OP has not been seen for almost a month, so may have moved on!

Those appear to be typical reverse SMA connectors used for Wi-Fi antennas. Based on the USB and HDMI connectors, that section of the device seems to be an HMI (Human Machine Interface).

Raspbian is the old name for Rasberry Pi OS. It’s a Linux distribution (based on Debian) for ARM-based RPis other than the RP2040 based Pico series. The RP2040 is a ARM but it doesn’t run an OS. It is programmed like an MCU with a dedicated program.

There are quite a few RPi compatible boards, but unless the hardware in that module is designed with the same systems as the RPi, even if it can run Linux it hardly makes sense to run RPi OS.

 

"Y" has described additional complications relative to the unidentified hardware.
And consider that even if MAX had exactly the correct part on his shelf to effect a repair, the TS would still have an undocumented control system that will have no recourse in the event of a future failure.
Replacement with a currently available system that is adequately documented would allow, at the very least, rapid acquisition of repair hardware when needed, and, at the most, having a programmed backup system on hand for immediate replacement of whatever might fail. I have done service in manufacturing plants that did have backup systems ready to use simply by switching on the power.

 

Hi all
I apologize for my recent absence from the forum due to personal issues.
Thank you for your understanding and for your kind replies.
I appreciate your support. i will try to dig into module and find more info.
