I am trying to poll 'W' link registers from a Mitsubishi i-Qr (R04EN) CPU. I want to read the value of each bit (for e.g. W109.0, W109.1, W109.2, etc) individually from the link registers, as each of these bits is linked to a separated output in the PLC program. I am attaching a screenshot of these tags from the PLC program.

I have configured these tags as follows in my Flexy 202:

• Server: Melsec
  
• Topic: A
  
• Address: W1090 for PLC address W109.0; W1091 for PLC address 109.1, etc
  
• Type: Boolean
  

With above configuration, the polled value is always 0; i.e., when the value changes to 1 in the PLC, I am still seeing 0 in my Flexy.

Note that my Melsec IOserver configuration is correct as I am able to read all the other tags properly from the same PLC.

Please inform the correct method to configure and poll the 'W' link registers.

Did you find a solution, Im facing the same issue

Hi,

I am not a super expert in Melsec but I know that some Mitsubishi PLCs are using addresses in Hexa/Octal or decimal. Like for the X and Y regsiters in FX5 https://hmsnetworks.blob.core.windows.ne...ba6256d7_6
So I would try to declare all the W registers in the Flexy and try to find your value.
