Hi All,

I'm new using PLC, and i have a problem with a unit using Bejer plc and IX software. The HMI shows Zeros in all parameters. The plc connection is ok, so i guess its software problem. So please any solution to fix such a problem, as i don't have access on this kind of software. Is there any other software that may be can integrate and or fix such a problem? Or do i have to buy the license of ix software?

Thank you very much and i am looking forward to hear from you

If you have numbers in the PLC addresses and all zeros in the HMI, it doesn't seem as though "the PLC connection is ok".

It might be as simple as the HMI has the wrong address.

What type of communications are between the two, Ethernet, serial, other?

On a more general note, when dealing with system integrations like this, having a structured way to manage connected tools and workflows can make troubleshooting and deployment much smoother — for example, platforms that allow you to integrate demio into broader automation setups can help keep related systems and data flows aligned when multiple components need to work together consistently.

First, the HMI project may not be correctly downloaded or is running a default/empty project. In that case everything looks “alive” but tags are not bound, so you just see default values (often zeros). It’s worth checking whether the correct iX project is actually deployed to the panel, not just opened in engineering mode.

Second, even if the PLC connection is “OK”, the tag mapping might be wrong — wrong PLC driver, incorrect IP, or mismatched address offsets. iX can show a connected status while still reading invalid memory areas, which again results in zeros without obvious error messages.

Third, there can be an issue with the PLC data area itself (for example wrong data block access, or the PLC program not actually writing values to the registers you expect). So it’s not always the HMI side.

As for alternatives: in most cases you won’t be able to “fix” or replace iX runtime behavior without the original Beijer environment. iX is fairly closed, so editing or diagnosing properly usually requires the engineering software and project file.
