Is there someone who has well known of UDP socket communication between Q03UDv CPU or Q03UDV and LCPU? I try to establish a socket between 2 Q03UDV cpus. Inittially evrything goes ok but after some days of well communication the socket breaks down. The connected HMI (GT1675) becomes inactive or responds extra too slow. In order to re-establish the socket comm i have to reset the cpus. I think it is ubnormal!!! Attached you can find the program of socket connection Do you know if the SC_SOCOPEN and SC_SOCCLOSE  instructions are requested? According to the manual "Q PLC Comm Via Bulit In Ethernet Port - 01042010 SH(NA)080811 Version C) on page 3-35 I think that instructions are not requested Thank you in advance for any help!  

Hi Gambit None possible cause from the list meets my case...Everything seems to be ok! How can I clear the receive area? Is there any special instruction?

Gambit I must apologize to you for wrong info that provide to you. I accidentally wrote  that the error code is 4188. It is FAULSE. The error code as you can see in the above atached file is 4181 from one side of socket and 4184 from the other side of socket.. 

Gambit tank you for your reply! What exactly do you mean with PLC communication settings? I have some sockets like Q03UDV<--->Q03UDV or Q03UDV<--->LCPU In cpus with Sockets  that does not work I get the error code 4184h from one side and 4188h from the other side. You can find attached a plc ethernet diagnostics screenshot with error codes (Q03UDV<--->Q03UDV). Thank you again!

aniki007 please send me your email account to send you back a project (GW Works2) included profibus DP communication with FR-F740 VFD, Allen Bradley PowerFlex5 VFD and AUMA actuator. The project is bigger than 3.9MB so I can not uploaded here... Thanks

Ok!!! Thanks a lot for your help! I understand! I will try it and I will post back the results!! Thanks again!!

Hello guys!!! My system constist of: CPU: Q03UDE Some I/O modules Some Intelligent Modules (Q68ADI,QJ71PB92V...) A High Speed Digital Input card QX80H (setting responce time 0.1msec) 1 digital input from QX80H occupied to count the pulse that a flow meter sends. The pulse corresponds to the totalizer of the Flow meter (FCI ST100 series Thermal Mass) and it has fixed width 0.5msec. The flow meter sends 4 pulses / minutes approximately according to current flow rate. My Main Program has scan time 2.4msec. I think that PLC ignores some pulses because of the pulse width is lower than scan time of my program. Is it right? So, the PlC program calculates wrong total flow.... What can I do to avoid this issue? Attached you can find a sketch what I mean... I though to program a time based interrupt every 0.3msec. Is it right and possible in Q03UDE CPU.....? If yes, how can to do it? Thanks a lot in advance for your any help!!!

Luke, excuse me for the late answer but I was very busy in my job. There are no other input cards with interrupt function enabled. Generally, there is no other interrupt function in my code. I'll try to catch the idea of the interrupt mechanism, reading Mitsubishi manuals, but too dark....Is there any code example in GX Works2 that can help me...I am not so familiar with GX Developer..... Thanks a lot again for your help!!!!   

Many thanks to all for your help.... AlexMota, of course i set the response time of QX80H at 0.1msec, without any result.... I use Q312B rack and QX80H card is on the last slot..Is it restrictive to use fixed time interrupt routine? Thanks again!!!

Hi to everyone, I use PowerFlex 520 drive on profibus (with adapter 25-COMM-P) for first time. I managed to start/stop/reference drive using Logic Command/Status I/O but didn't manage to get output current using datalinks mechanism. I configured DP master (Mitsubishi Q PLC, QJ71PB92V) as shown in the attached picture. The main problem is that trying to modify C161-C164 (Opt Data In 1-4) parameters drive does not accept the entered values and it turns back to value "0". First, I disabled I/O connection with the controller Disconnecting the drive from the network. On the other hand, drives allow me to change parameters C165-C168 (Opt Data Out 1-4) but these are out paramenetrs (from the controller's point of view). Is there any guy that managed to get the output current  in any way on profibus network? Thanks a lot for your help in advance! I post this message in Allen Bradley Forum, too.

Kaare_t, thank you for your reply!! The GSD file is ok. Communication is established without any problem. I use litle endian setting. I can absolutely control the drive with logic commands such as start/stop, speed reference, etc. and get logic status from the network. I can not get additional info from the drive like output current, etc. The corresponding parameters of the drive looks like to be locked. I can not change the default values  although I follow the manual step by step....

It is unbelievable!!!! That was!!!! Power off/on physically. Last 3 days I did only soft reset. Now, everything is ok! Thank you very much for your help. Thanks!!!!

Hi to all! IAn HMI E1043 is connected with Q03UDE CPU. All works fine except from following...HMI can read any register from the controller but it can not write to the same register. Trying to modify the current value from one register I get the error: " Error 0055 Stn 0". I can not find the meaning of the error in any manual. Any help would be gretaly appreciate!!! Thanks a lot !!!

Thanks! Uploaded some photo from settings(HMI side) for a register (File register R8) that I can not modify from HMI. HMI settings1.bmp HMI settings2.bmp Plc settings.bmp Thanks a lot!

Unfortunately, your tip is not the solution. I did this change but I get the same error "Error 0055 Stn0". Any idea where can I find the error exlanaion? What else to try??? Thank you again!!

Kaare_t, Thank you very much for your help. I spent a whole day to try everything. Many many thanks!!!!!

Hello to everyone! I have an analog card Q68ADI and 2 Pt1000 termometers with 4-20mA transmitter. Pt1000 are connected to Q68ADI. With Function block from Analog Q400 library can read the analog value and then the digital value from -288 to 12000 (in high rsolution mode). I would like to convert the digital value in Celsius degree from 0 -100 oC. Which is the right way to do it?? Thanks for your help in advance!

Thanks to all for your help! At this moment I used IntScaled_V200 library from MyMitsubishi Data base and I think everything is ok. Also there is FltScaled_V200 in the same data base. Plcfreak, what are the differences between any saling Function block and SCL/DSCL instructions? Are there advantages?? Thanks!

Thank you for all!!! Everything is ok and the plc Q03UDE can communicate with E1043 operator panel succesfully. The final right settings: PLC: Built-in Ethernet Port Open settings-->Open settings-->UDP protocol-->Open System: MC protocol-->Host Station port No.: 1280 (in HEX) HMI: Peripherals-->Controller-->MC Protocol (should be updated terminal drivers via internet. File-->update etc). I have E-Designer 7.50 and the "MC protocol driver" did not exist in controller list (MELSEC controller) Then Properties-->UDP connection-->Settings tab-->Communication mode: UDP-->Use MELSECNET: Disable-->Stations Tab-->Station: 0 (for me)-->IP adrress: 192.168.3.39 (IP address of Q03UDE CPU)--> Port: 4736 (1280 in DEC format) If I change Host station port No. (from PLC side) to another port than 1280 the communication is continued to be ok. I think UDP port of does not influence the communcation between controller and HMI. Thank you very nuch for your help!!

Hi to all!! I've posted in forum 2-3 times in the past. I am new user with Q-series PLC. I have an operator panel E1043 and I would like to connect it to Q03UDE (Build in ETHERNET port) via Ethernet, but until now without succesful! PC can communicate with PLC via ethernet succesfuly. PC can communicate with HMI via ethernet succesfuly. But HMI can not communicate with PLC via ethernet succesfuly. The cable is crossed PC IP: 192.168.3.3 PLC IP: 192.168.3.39 HMI IP: 192.168.3.40 Connecting HMI directly to PLC I get on HMI screen the next error: "1:Error IP stn 39" Please help!!! Is there any wizard how to connect E-series with Q plc via ethernet??? Any help would greatly appreciate!!!!! Thanks a lot!!!

Thanks to all for your help! Gambit where will I lookig for MC Protocol properties? Thank you again!!!

Thank you very much Sparky! I will contact to local Mistsubishi distributor iin Greece. When I will have any answer I will forward it to you!!!! Thanks!!!

Hi to all!! I am trying to state E1032 data logger. I use E-designer 7.50. I can't understand the Help of E-designer (I think is very pure help) and then it seems not start the data logging and I can't transfer the data logger to external USB flash memory. So, there is a demo project about data logging?? The demo project that included in E-designer does not contain data logging functions. Please, give any help how to make the data logger to work!!! Thanks a lot in advance for any help!!!

Thanks Inntele and Dariush. I managed to make data logger backup. Thank you again. Please, I have one more question..... Opening the *.CSV file after data logger backup there are 4 columns for example. But there are no title in every column. How to make to display the name of each data logger signal as column title in *.csv file????? Thanks,thanks,thanks.....
