MITSUBISHI AJ71E71 ETHERNET COMMUNICATION

[deep_arvind 0]

can anybody tell me how to do ethernet communication between MITSUBISHI AJ71E71 Ethernet Module & GX DEVELOPER. IS it possible or not.

yes, it is possible. first you have to set up the network parameter. then download the parameter with serial cable to the plc. with menu online -> transfer setup you can configure the communication settings between module and GX Developer. use the ethernet board and do your settings. for futher information take the GX Developer Reference Manual

thanks for the help. But ihave already tried that, With "transfer setup" parametrers, I am giving a IP 10.91.54.79 & port addr. of 100H. it is pinging from the Copmuter but the ping test from GX DEVELOPER IS not working.

The ethernet card needs to be considered as a Melsecnet card, i.e. the station number, network number and group number are important for it to communicate with a GX Developer connection correctly. You must set up the card to a particular station number e.g. 1 When you do the transfer setup of your PC you must give yourself a "Melsecnet" station number in the PC side I/F which is unique to your network, in this instance you could use "2"

this is what i was using not so long ago (you may want to adjust IP address etc.):

and the transfer setup was like this:

hi panic mode!!, thanks for replying , but we are trying with A3A cpu, and we are not getting the Ethernet tab on Network Parameter, and also while trying to change the Transfer setup we dont get any setting by clicking on the PC side I/F ---> Ethernet Board , please see the attachment...actually we are having the following PLC configuration... A1ACPU,and the ethernet card on the PLC is AJ71E71(and we are using Cheapernet), and we are having GX-Developer 8.01b on win XP having ethernet card installed on the PC. we are using transceiver for ethernet to cheapernet conversion, and we been able to ping the PLC from our PC , but the main thing is that we are not ale to ping the PLC fron the GX, ...that means we are not able to communicate with the PLC. .... untitled.

I have not tried to do this myself but I suspect that you will need to include PLC code to open a port on the ethernet card before you can connect to it with GX Developer (this is not needed for a Q processor). Do you have this code in your PLC programme?

Or set start communication "output"?

Hi All., Please Reffer this attach file., you must make a ladder prpgramming for ethernet configuration data. you can copy the example programming from that manual regards Adi AJ71E71_User_Manual.pdf
