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.

0.1ms more than enough for your 2ms fixed scan time, but you definitely can change going to Parameters/FX5UJCPU/Module Parameters/Input response time You also need to check what is your sensors respond time... What was the point of fixed scan time? why so short?

What is your input response time set to?

Looks good to me.

Here is a link to the manual https://dl.mitsubishielectric.com/dl/fa/document/manual/plc/sh080006/sh080006w.pdf

7D13H is Receive wait timeout error. Here is what in remedy ... Check if the reception is interrupted due to some reason such as DTR control.  Check the cables for disconnection.  Check the sending device for an error.  Using the circuit trace function (communication data monitoring function), check if: 1) Transmissions from external devices are interrupted. 2) Any data are missing due to a receive error. 3) An error exists in the data (packet) sent from the other device.

Your high speed counter seem to set correctly. What exactly is wrong with the execution? Have you tried to reduce input response time to less than 0.1ms? Can you post your high speed counter settings page, I wonder if you set Long counter Specification in Other TAB.

I wonder how the name got changed in the beginning. GX Developer would not do that.... Nice catch any way!!!

What is the PLC model?

Seems corrupted DB. No way to recover. Do you know if it was in English or foreign language? I tried to open with GX works 2 as other data with no luck, it complained on corrupted data of illegal characters used.

The problem is coming from HMI. Have you tried to start new project from scratch?
