Trying to get to number displays working to display the first 3 digits in D1005. Have done it over 20 times with the FX2N-485-BD and never had a problem.

The settings for the display are
Buad rate 1200
8 bits
No parity
1 stop.

I am sending the following, is this correct ?

[mov h359 D8120]

Thanks in advance.

I just set it in PLC parameters.

I am not make sure ,but you can try this below setting

9600 Buad rate
E parity
7 bits
1 stop

LD M8002
MOV H6086 D8120

LD M8002
MOV K0 D8129

LD M8002
MOV H0 D8121

Hello. I have a sytem i sell to one customer. FX3UC with RS485 BD card. I use GX IEC Developer
I remember the first time i did this i had problems.
I got support through Beijer here in Norway. They found out that i also needed GX Developer installed to get the programming to work the BD module uses a winsoc version from GX Developer.
Not sure all the things they did but now it works every time.
I also got some librarys with ADPRW and MODBUS FX3U Master funktions.

You have the wrong settings for D8120. For your setup you will need:

[MOV H1051 D8120]

I just switched from a 485-BD to a 485-ADP, because I need a full-duplex communication.
So I took the BD out and attached the ADP and adjusted a few things - it does not work.
Am I correct that the ADP is still Channel 1, since there is no 485-BD attached to the PLC anymore?

I read the wiring is differently?
But I could not find any difference in the manual?!

Attached is my code...

Help is appreciated.\

Cheers

So now you have:
1x FX3U-CNV-BD
1x FX3U-485-ADP

right?

Correct

1x FX3U-CNV-BD
1x FX3U-485-ADP
and
1x FX3U-232-ADP

You are correct. You can still use the first ADP card as channel 1 (same as BD), so it should work..... I don't have GX Developer installed on the machine I'm currently on so I can't look at it right now

OK,
I finally got it working.
I can send commands which proved to work with an IMS Drive.
So now I spent some time with the IMS drive to give me feedback via RS485 (positions).
I was able to read everything out via HyperTerminal, so the drive does send, but I can't see it in the PLC.

Again,
I can send commands to the client.
The client send stuff back, but I can't see it in the PLC.
My settings seem to be right, but I guess somethings fishy with my program.

Does anybody mind to explain me what I screwed up?
I am scanning a register for hex numbers,
which triggers a command.
What I probably did wrong is: I do not read in?! Well, I don't know :D


Thanks a lot!
