  1. Hi I would like to know how to turn of COM.ERR LED on FX3GE PLC. If somebody has a tip, would be great. The FX3GE has, according to the documentation, a FX3-ENET-ADP module built in. Our setup: We have a FX3U as master and four slaves FX3GE. FX3U->FX3-ENET(Ethernet Module)->Ethernet switch -> Four FX3GE PLCs The code in FX3U reads and sends data with the library from Mitsubishi. Basically, it works, but out of nowhere there is an error 2558, Command block x00BF. And the LED is on. We have no malfunctioning on the machine. Subsequent commands/data get through. So, how do we clear the error LED? I have now read many documents and could not find a solution. It works in GXWorks2. There is a button on the "network diagnostic" dialog. But I cannot sit all the time at the customers site to manually clear the LED. It would be of course better, if no error occurs, but I was unable so far to find the correct settings. For example there are many timing settings on the FX3-ENET module to be set with FX Configurator. But I could not find the timing settings for the FX3-ENET-ADP and the help file  of the library says they should match. Further, what do you think, is it ok to run the library code to communicate with 4 PLC's unsynchronized? The master powers up and starts communication with all four slave PLC's at once. To be correct, I'm new to PLC's and don't know the exact execution time of the code/ladder blocks. But I found no synchronization mechanism only four times the same blocks with different IP's / ports fed in. It seems to me they run at more or less arbitrary time and with delays on the network...well....there may be interactions. Any tips or ideas are welcome!
  2. What am I doing wrong? I have an FX3GE PLC. I have set up the IP address 192.168.3.254 and I am able to connect with my laptop running GX Works2 version 1.501X. I also have a GS2107 that I have set up with IP address 192.168.3.18 (Default). I can communicate with my laptop running GT Designer3 version 1.151H. The HMI is still failing to communicate with the PLC. I have followed different threads on this forum, tried different port settings on the HMI. I have attached my settings. Is there anything else I need to set?
  3. Fx3ge to Fx3ge communication trough lan

    Hello, For my assignment, I need to control lights from 2 seperate locations. I have two FX3GE-24M plc's connected through a LAN network. The idea is that when input X004 gets high, relays Y000 to Y004 gets disabled. I'm trying to use the Fixed Buffer communication protocol.  Master IP address: 192.168.1.80 Slave IP address: 192.168.1.81 I'm using GX Works2 together with the FX configurator  I'm lost in all the different datasheets... Could someone point me to the direction on what settings i need to change using fx configurator and a basic program of communication?  Thanks in advance, Dennis
  4. Hello everybody. I am looking for a solution for an FX3U with mounted FX3U-ENET on the right, to communicate with an FX3GE. I need to read and write some device in the FX3GE from the FX3U. I have made a paired connection in the FX3U-ENET module and made an MC connection in the FX3G. But how can I send or read data? Is there another solution apart from the MC-Protocoll? I am using GXW2 version 1.551z. Languages: ST or FBD Thank you in advance Dave
  5. HI Everyone,  Recently i have bought a plc fx3ge and gt2000 hmi .the problem is that whenever i use a device address d280.b1 in hmi .i am not able to use the same address in gx works for plc (LD D280.1).can anyone help me with this problem.   
  6. We are communicating FX3GE PLC with Vijeo Citect SCADA. We tried various protocols such as MelsecNET, MelsecFX2N, Melsec1, etc. If you know how please help.
  7. Hi. I'm hoping someone can give me an answer on this problem I'm having with a FX3GE PLC. I am trying to get a FX3GE plc to communicate to a drive over RS485 using a FX3G-485-BD card. In GXworks2. But am having no luck.  I have tried changing the PLC communication settings in PLC parameters between CH1 and CH2, But am unable to get any communication working on the front port. I have also tested with a FX3G-232-BD RS232 card and have the same problems. There is no activity on the SD RD led's and no data being sent. If I put the FX3G-485-BD card in a FX3G or FX3S PLC I have running the same code it works fine. So the problem I'm having is with the FX3GE PLC Please can someone tell me what the difference is with the front Communication port on the FX3G and the FX3GE. And how I can get the FX3G-485-BD card working on the FX3GE PLC. Thanks
  8. Hi there! I need to set up a communication link between an FX3GE PLC and a Melfa RV-2F-D robot with a CR750-D controller. Can I use the PLC's built in ethernet port for this? Is there a native driver for this (i.e. to read a register from the PLC into the robot controller)? Or should I use some kind of a no protocol communication? We also have a GT1455 in the setup and had in the past a solution where the robot was talking to an FX3U trough the HMI, but there was a lag in the communication which I would like to avoid. I am new to Mitsubishi so please bear with me. Thanks!
  9. Hi guys! As the title explains, i wanna move a value to 210 -> 220... is there a function for that or do i have to make a MOV for every single dataregistry (look at picture)? Its an mitsubishi FX3GE PLC programmed in GxWorks2. Br, Jim  
  10. Hello I have PLC FX3GE-24MR/ES with FX3G-485-BD board  and rail350 electric meter http://www.northern-design.co.uk/docs/manuals/ND%20PowerRail350%20Modbus%20Comms%20Manual.pdf I want to ask you. Is it possible Modbus RTU Communication between PLC FX3GE-24MR/ES and rail350 electric meter? If yes, then maybe you give advice how need to read data of ladder languages
  11. Dear Sir, I want to read data (Digital Input say X0 (Local PLC) and after some additional logic i want write to Y0 (Remote FX3GE PLC on same network) from one Mitsubishi FX3GE and Write to another FX3GE on the same network. Master PLC IP Address 192.168.0.40 Slave PLC IP Address 192.168.0.50 Atif
  12. Hello again! This time I have issues with PWM Block in GX Works 2. Im using it to control output for Rudder Machine. S1 Time is Pulse time S2 is response wait time. I follow the rules that S1, S2 cannot be zero, N2<N1. I compile and run the program. Everything is ok, program works perfectly. Sometimes when I modify instructions in PWM Rung - i get an error No. Result Data Name Class Content Error Code 4 ERROR POU_01 Program compile Invalid list code 'PWM D992 D990 M1524'(Ladder Block No.7) F0161 I pinpoint that I use 2 block of PWM one for each side. They cannot work at the same time. See attachments with code Thank you in advance!
  13. can anyone please provide me "keithley Model 7009-5 Shielded RS-232 Cable configuration." ? for communication with fx-3ge plc to nanovoltmeter 2182 controller.
