Can you sent a picture of your comm settings in GXWorks?

Have you tried to ping your PLC when you connected to eWon? If ping replied OK, must be your settings in GXWorks comms.

What output are you expecting from Barcode reader? Do you have HMI display in your machine? Is there a specific reason for ethernet connection?

Also check if Monitoring Current Values are set Show always.

For 3C on FX5U format should be in ASCII not binary

I think you referencing to a wrong manual. Here is the one you need for FX5UC. Check part 6 MC protocol. It definitely asking for 3C frame... https://dl.mitsubishielectric.com/dl/fa/document/manual/plcf/sh082625eng/sh082625engf.pdf Could not upload whole file, here is Part 6 only FX5UC part 6 comm manual.pdf

Also what is the reason to read blocks with 0406 command? You ca read a range on devices with 0401. IF in binary - 0x50, 0x00, # Subheader (2B) 0x00, 0xFF, # Network Number & PLC Number (2B) 0x0C, 0x00, # Request Length (2B) 0x01, 0x04, # Command Code (Read Word Device - 0x0401) 0x00, 0x00, # Subcommand (2B) 0x2E, 0xE1, 0x00, # Start Address (D12001 - 3B) 0xA8, #Device code (D in binary message is A8 - 1B) 0x06, 0x00 # Number of Points to Read (2B) This message should read 6 words starting from D12001. Or this will read 10 points from starting D0 0x50, 0x00, // Sub Header 0x00, 0xFF, 0xFF, 0x03, 0x00, // Route 0x0C, 0x00, // Request Length 0x00, 0x00, // Monitoring Timer 0x01, 0x04, 0x00, 0x00, // Command 0x00, 0x00, 0x00, // Device Address 0xA8, // Device Prefix 0x10, 0x00 // Device Length the only reason for 0406 is you can read bits and words in the same message, or blocks of words/bits that are not consecutive. Personally never tried...

Hello, it seems your message format is incorrect. It was a discussion on this forum some time ago, but we were talking about Q03UDE PLC. I do not have a manual for FX5UC MC protocol, but will look in to it. But here is a link for MC protocol libraries, hope this will help. https://github.com/YudaiKitamura/McpX

Have you tried smaller size than 64?

Mitsubishi has some training videos on their website and there is a YouTube channel as well. But to me it was easy transition and I personally like Mitsu more than AB...

Need more info, how everything connected.

Sorry missed you need to connect five drives. In this case you will need a distributor boxes (splitters) BMJ-8. the cable above is for HMI to first splitter (or to drive if only one used). I added the rest of the cables here. The runs can be up to 30m/100ft total, amount of drives up to 10. They requesting to use cables from splitter to drive as short as possible...

Here is a pin out.

Also do not think you need to bring sm8251on to enable your counter that is what HIOEN for, it enables 16 bit counter you set for CH1. Also L51 A/B counter is UP/DOWN counter, it counts up if A is ON before B comes ON, and counts down if B comes ON before A comes ON. so you can catch your encoder rotation direction if needed using high speed comparation.
