Address format Mitsubishi PLC

[Boushard]

Hi,

I'm new with Advance HMI and I try to use it with Mitsubishi PLC and I just wonder what is the correct "PLCAddress" format should I use!

I know this is a very basic use but can't find the correct format!

Thanks guys!

Which driver are you using?

[Boushard]

ModbusTCPcom

Try couple address found on the web and receive "Com Error -999. No values returned from driver".   I can see in the PLC programming software that my application communicate with the PLC.

I am not sure if this might help, but take a look at it:

http://www.automationsystemsandcontrols.net.au/PDF's%20Mitsubishi/Manuals/FPLC/Mitsubishi%20FX-PLC%20Addressing,%20Instruction%20&%20Device%20List%20Quick%20Ref.pdf

What addresses did you try? 40000, 40001, L40000, or (400000,63)

Store something in D300, and do a read on 400500

[Boushard]

Try every adresses you gave and no go.

The 400500 seem to work, but I have a "No value returned from driver". I put the address in PLCAddressValue!

I also have a "No Response from PLC(21)" error.

I've just tried "0001030".  Now I only have a "No Response from PLC(21)" error on read!

And when I try write instruction, I have a "WRITE FAILED, No Data Return" error.  I think I'm on my way to succed!!

Your errors should indicate that there is no proper communication between the application and the plc.

Check your plc programming software to see what parameters it is using to communicate with the plc.


For the addressing part, sections 3 and 4 of this manual seem to indicate standard Modbus addressing for this particular Mitsubishi plc (Archie could confirm whether this is correct):

Just for the sake of asking.

Is the PLC in Run mode?
Are you sure you have the correct IP Setup in the driver? , ie IPaddress and TcpipPort of the PLC

Also, Which version of AHMI are you using?

[Boushard]

Just for the sake of asking.

Is the PLC in Run mode?  Yes it is
Are you sure you have the correct IP Setup in the driver? , ie IPaddress and TcpipPort of the PLC  I'm sure about the IP, the port # is 5556 witch is, according to mitsubishi, correct.

Also, Which version of AHMI are you using? Downloaded the last version 3.99N

What is the exact model of your Mitsubishi plc?

Also, there is an interesting post in the following link suggesting that port numbers are in hex format and also mention some "pairing" feature:

Could you confirm if any of these apply to your plc?

[Godra]

Eventually, you could do a Wireshark capture of both your plc programming software talking to the plc and AHMI application trying to talk to the plc.

Archie would have to be the one to try and decipher those packets.

The setup is:

PLC: FX3U-32MT/DSS
Ethernet Card: FX3U-ENET-ADP
Drive: MR-JE-20A
Servo:HG-KN23JK

Software:

VisualStudio 2013/15
MX-Component V4.09K
GX-Works 2

Using a web browser, can you access your ethernet card web page?

ModBus TCP should be using port 502. Also if using version n, then d/l the patch
