Start GX Works 2 and choose project => open other data = open other project and select the GX Developer project

Well for this module only one Channel is converted at a time.  So first only K0 or K 1 is send to bit 0 selecting either Channel 1 or 2 Then this is activated by setting bit 1. Which means either H2 (bin 10) for channel 1 and H3 (bin 11)for channel 2

The First (K0) means your adressing the First special module in an FX config. K0 then K1 then K2 etc. The second (K17) Means the BFM addres K17  The Third (H0000) is the value wou wish to write to the BFM (When it's a from instruction where the value should go For instance D0 or K2M100) The fourth (K1) means batching. you can write a value to multiple BFM addresses. K1 means only this adress (K3 would write the value also to the next two addresses)    Hope this makes in Clearer

Haha So True

Try running GX Developer as Admin

You're welcome

In thess cases It's not neccesarry to make a back-up. Ifit's just on master and one slave. the FX3U and the A series plc don't have the auto refresh function like the newer PLC system. All the I/O mapping in this case are done via TO from instructions. For instance for the A series PLC. you can check a to and From instruction for BFM 0 and 960. This will have the I/O inf you need. Download the manuals for the A1SJ71PB9D and the FX3U-64DP-M and take a look at the sample programs. If you have any questions let us know

Both will overwrite the same addresses each time. So the value used will depend who did the last write before a new scan starts.

It work fine on my Windows 7 enterprise 64 bit.  I use GX Dev 8.118Y  and GX config DN 1.23Z  

I bought this set vie DIATREND JAPAN http://www.diatrend.com/IFcable/difc-fsb3a.htm It's not cheap but now I have all Cables I need for Mitsubishi in a single set. All Via USB  

Well. The code looks oke accept for a one thing.: 1) The G.INPUT start address should be U0A instead of U0A0 The string being received is this with an end character or Fixed length? If it is with an end char is this CrLF (Hex0A0D) ?    

@Kaare_t is right the FB are easier but even if you do not want to use FB's all you do is set the end character if you have one and then use the G.input en G.ouput instructions. All the comm parameters are set in the special function utill. Its pretty straight forward  

Good Christmas

You should get download the iQ-Work 2. That is more recent.  During installation it will ask which versions you would like to update

I think All you want to do is MOV D0 K2Y0. This will put the binary value of D0 to Y0-Y7. If you want that the value of D0 is the out then look at the ENCO DECO instrcutions

You have created a ring ethernet network structure this should be a bus. You've probably created a broadcasting loop. Did the CPU's go into WDT??? Than this probably is the cause of the problem.  

IN and DINT are not needed in GX Developer only in GX IEC Developer and GX Works structured mode

Sorry not familiar with that type of HMI. But it's a pretty standard sort of feature.  Maybe you can check via your Distributeur?

Why not just use MX Sheet and delete the sending out of RAW data part of the program?

Yes but that is as a slave.  You will need to create the requests from your code. That is why those FB's we're created. Why not use the HMI. The costs of a GT2103 is not that high and will reduce your programming time considerably  

The problem is that the FX3GE only supports MC protocol (1E) So you can;t use fixed buffer. I would suggest just buying a small GT2103 connect the FX via de CPU port and the system Q via Ethernet. The use the Device data transfer function of the GT2103 to exchange the data

Have you checked if ALL the parameters of both Axis are the same? For instance the Command in position range or the Bias Speed at start      

Can you tell us more about your system Setup?

There are some FB which simulate the MC protocol which you can download from the European Mitsubishi site. Then you only have to create a port on on PLC. And use the FB in the other project    

Which Software are you using ?
