Hi, i've a system with a FX2n connected with GOT900 with 422. A PC is connected to GOT via RS232. In the PC there is a program that use MX sheet for write into the PLC "numbers" every 1 second. The total sequence is made of 8000 logging: 8000 seconds. After circa 200 logging mx starts to have delay and data dropout. If a limit the sheet to 2500-3000 write all goes well. Now my intention is to speed up the connection with a Ethernet connection. Id like to use a ENET-ADAPT from Mitsub. So my questions are: 1) I think to leave the link between the GOT and the PLC via 422 2) Add the ENET-ADP to FX2N and connect the PC to PLC via Ethernet. 3) Apart the setting of MX components an MX sheet (kind of ports,TCP/IP adress etc) what is necessary add to the GX Developer code(Software) that now goes via RS232? In other words,if i change only the setting of communication parameters the Main program developed for 232 is ok,or i must add,chenge something?? Tahnks for any Help Regards, MAX

Yes but how many sample i must take? And how? Thanks Bye MAX

Is there a predefinied function for calculate the RMS value of a signal using FX2n and FX4AD Thanks

Thanks! Now this is what i've tested today: the original Mx sheet has 8 col of 1000 rows so there are 8000 step in PLC program,organized as 100 step for wite a device and 100 ather step so i wite 100 cell with a device and other 1oo with oter device so till 8000 steps in total. If i change the MX Sheeet in 3000 step only i haven't delay on timing and no dropout. With sheet longer the timing on writing is delayed and also dropout arrives! So i could be really a low speed comunication? Boh!!??? Best regards, MAX

So i shlould leave the GOT900 connected to PLC as is now(i think via rs422),but i shlould add the FX2N 232BD to PLC and connect the PC to FX2N 232BD? In the user giude of FX2N 232BD,there is a notice,that says that only 1 communication board can be connected to PLC. My doubt now is whre can i connect another serial borad to PLC when there is already a 9pin board(422?) connect? Best regards, MAX

Thanks all! My Serial port (sidePC) communicate with PLC via GOT on 422. So in communication setting on MC communication menu i've setted com to FX2n(in reality the communiction to fx2n in made by GOT900) is correct this configuration? Last thing, i've nociced that if a change setting of a MX sheet that as for example 20 cells and i delete the cell2 and resetting cell 2 this cell will'be dyspalyed on summary mx cell in last position,not in sequence. Is it normal? Or then the mx sheet load the cell 2 after the cell 20? Thanks Best regards, MAX

Hi, thanks a lot for your answer! I've the manual but i can't find the restriction that you mentioned. Do you know the numper of the page? Do you think the speedng up to 115200 the speed of com port could be better? Bye, MAX

Hello, i've abig problem with MX Sheet with a FX2n PLC My routine write every 1 second a number on a Fx2n an for about 5000 seconds. The problem is that PLC receive this number not every 1 second but after a different time. So after for example 100 second PLc has only 93 number end this error became more big at 1000 seconds edn so on.Sometimes also the number doesn't arrives at the plc..........seems to be lost......... What can be the problem? A wrong setting of speed of 232 port of PC that has in memory the mx excel sheet? Some body had this type of problem? Thanks for any help Bye MAX

Hi, i've a Fx2 connected to a GT900 and i cominicate from my PC to FX2N via GOT. Now the problem: i've a program made with MX sheet that write into the PLC every 5 second for 2000 seconds. But always after only 100 second the plc stop to receive the data from the MX sheet. I've tried everithing but always after 100 second mx stop to write into the PLC. What can be the problem? THanks in advance for any help. Bye MAX

Thanks! So before i use GX Developer and i download the program to PLC. Then vwth FX-PCS-du-win-e i download the program to GOT,always using the 232 connector of the GOT. It is OK? Thanks Ciao MAX

Hi, i littel question: i've a system composed by a PLC Mitsubishi FX2N + a Touch Screen GOT940 connected. The question: i've made a progam with GX Developer for the PLC and a program for the GOT940 with FX-PCS-du-win-e . Can i upload the 2 program(one for the PLC and the other for the GOT) from the RS232 port on the GOT with a normal 232-232 cable? Or i must before upload the program made with GX to the PLC(with a SC-09 cable) and then upload the program made with FX-PCS-DU-WIN-E to the GOT with a normal 232-232 cable? Thnks for any help
