From: FX3U-ENET-ADP User's Manual - Up to 4 connections can be established and used at the same time in the Ethernet adapter.    

Right, I thought you might have created some since your post. Check you PM, I sent a small program.

Interesting. What about the byte order? The next day. Years ago I wrote some routines to covert to/from FFP - 754. I went and looked at the code and while it has some bit shifting it is not only shifting. For example the exponent is biased differently. If you have some working code that converts both directions, is only shifting and maybe an and/or or two, I would really like to see and test the code.  

IIRC, the PLC provides routines to convert from/to SAIA native Motorola FFP and IEEE 754.

Hello, Or perhaps you could use a program, like PeakHMI, that can access the SAIA PLC using native SAIA protocol. FYI, SAIA uses the "Motorola Fast Floating Point", FFP for floats.

Very good. I suspect the port number was OK, you can test it. Setting up the send and receive fixed buffer.

Using PeakHMI or your code?  

I looked at the settings for an FX project. Here is a screen capture.  

Zip up the GXWorks project and post it here or PM me

Hello, There is configuration that is required. See my first response in this thread: https://forums.mrplc.com/index.php?/topic/41731-fx3ge-communication-with-kepserverex-via-udp-protocol/#comment-190141 It might help.

  I had the same results, 4003 bytes.  

His original post had MODBUS and the point about using Wireshark is 100% spot on.

Hi, PeakHMI could work for you.

I read the manual portion (MULTIPLE MEMORY AREA READ) and yes that does what you want if your PLC supports "C" series commands. Nice find.

You could convert to string and process each character to a number. Or  you could divide by 10,  multiple the remainder by 10. Then subtract the remainder from the divide result and repeat the above line until a single digit remains.
