  4. Hi there, Im having issues controlling ATV 320 VSDs over Modbus RTU with a M221 plc, does anyone have any pointers for me to look at? I believe I Have set everything up correctly but when I run the program on the plc the atv's just stay in 'NST' state I have included screenshots if they are any use   My speed reference in this example is taken from the memory word %MW0 which I am inputting via a HMI   I have addressed all my ATVs accordingly in there setting with the correct Modbus parameters and selected Modbus under the FR1 configuration, am I missing anything?? Any help is appreciated as I am really struggling   Tom
  5. MC protocol

    Hello once again, before I'll dive into mitsu manuals, does anyone of you know if there is some special relay signaling that PLC (FX3GE) have lost communication via MC protocol? Thank you in advance
  6. 1769-SM2

    Hello. I have a communication problem between an L30ER and SM2 module. It gives me a message error 16#001e, extended err code: 16#0000_0002, Error Text :Embedded service resulted in error. I have a Lovato network analyzer connected to SM2 module via Modbus RTU, on channel 1. The setting in the MSG instruction are: Configuration:Service type - Custom, Message type - CIP generic, service code 4b, Class 33f, instance 0, attribute 0, Source CH1_REQ[0] - INT[10], CH1_RESP[0] - INT[10]; Communication: slot 4, port 2, channel 1,  Connected - not checked. baud rate is 9600, DSI/RTU is 5, format 8-N-1. the channel led from the SM2 module is flashing. I read the value at a 2s. The rung is: XIO.TON.EN+TON.2s.EN+MSG.EN. The Cable betweenSM2 and Net.Anal is a CAT5, pins 4(A) and 5(B) Maybe someone has a clue.
  7. Modbus Addressing in Weintek HMI

    Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.
  8. 2 PLC WITH ONE HMI

    hi.   Can i connect two plc mitsubishi with one hmi . is so .. can u guide the connection between them . Hmi is of weintek.  one plc is FX1S and the second is FX2n
  9. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  10. hy everyone.. I want to communication inverter SJ700 to hmi mitsubishi GS2017 for read an code error in interface HMI? is it possible to communication between them?
  11. Hi everybody, I have a GT2310 communicating with the Mitsubishi F800 VFD. I am using the Freqrol 800 communication driver, connected to the RS-485 terminals of the GOT and on the F800. The comm settings are the same on both devices. I also tried to use the “auto negotiation” setup. I have communication between the two devices. I can read and write to F800 registers.   Anyways, The GT designer diagnostics is complaining about a communication error in the system alarms. The error can be reset but it will appear again.   This also happened when I created a new, empty project where just the communication was setup as described above.   Did anyone experienced the problem and how to troubleshoot / solve this?   Best regards
  12. Hello I have a problem with dl-ep1 ethernet modul. I connected the module to a IL-1000 sensor amplifier. There is some problem with the communication. How should I adjust ? I made some pic about the trouble. The sensor is a IL-600 laser distance sensor. I dont know yet how can I get the actual value.  Anybody knows how to set this modul ? If I think correctly after the right setting, if I check the sensor output:0 then, I can see the actual value of the IL-600 sensor. But unfortunatelly this part also not so clear for me, because I can connect about 15 sensor this ethernet modul.  Thank you so much if anybody help.
  13. HI All, i am new to this site, if anyone can help me out for below topic.

Thanks in advance  
  14. CP1L-EL TCP/IP with VideoJet Printer

    Hello, My previous topic was want to establish communication CP1E --> Videojeet Printer using RS232 serial cable. this project test SUCCESS. by the way distance from printer and PLC was very far almost 500meter. so printer technical team request to use tcp communication using cat5e cable. Problem: 1. I'm using TCP communication protocol that need me to have open,send,receive,close port. 2. Communication testing with PC Hyper Terminal --> OK but HT need in waiting call mode, i don't know why. 3. Using printer no result show. how i'm suppose to know communication already establish? 4. Communication setting on PLC Setting-Built in Enthernet need to add other communication device.? here i'm share some programs to give more understanding. Thanksm TCP with printer.cxp

  16. WRITE MULTIPLE REGISTER MODBUS

    Hallo my name is Danu, i have a CP1E wirh CP1W-CIF11 and connect to modbus RTU device, i have done with write single coil, write single register,  read single register and read multiple register. But i try to write multiple register,  the indicator of CP1W-CIF11 is off and if i check d memory its no data. I attached my cx programmer. Can you help me create write multiple register in cx programmer?  Thank you AD4402-modbus edit edit edit edit edit.cxp
  17. Hello everyone! Briefly introduction, I would like to communicate and test the following hardwares: 1- Omron CP1E (using an Option Port CP1W-CIF11) ; and 2- Arduino Nano using MAX485 RS485 transceiver. The CP1E will operate in "Modbus-RTU simple master" as illustrated in image 01. The arduino will be in slave mode address 1 and the library used is "SimpleModbus NG" ( https://github.com/angeloc/simplemodbusng/tree/master/SimpleModbusSlave ). Taking the sample in official manual ( https://industrial.omron.eu/en/services-support/technical-tools/downloads#cp1e ) , pages 248-253 in the "CP1E CPU Unit Software User's Manual" (Image 04) describes a sample communication to an "Inverter Slave". I want to use the Arduino Slave as the Inverter Slave just to be sure that all previous steps are correct. Therefore, I would like to know: 1- As illustrated in Image 02, Am I missing any resistors? 2- Should I connect the GND to the FG? 3- In this scenario, the DIP switch setup should be as illustrated in image 03? Only DIP4 is OFF. 4- Can I test it just forcing A641.00 and checking the DM Area Data, as shown in Image 05? The code used in it is the following: // Wiring: Arduino and MAX485 // RX0 - RO // TX1 - DI // D2 - DE/RE #include "SimpleModbusSlave.h" enum { REGISTER_0, REGISTER_1, REGISTER_2, REGISTER_3, REGISTER_4, REGISTER_5, REGISTER_6, REGISTER_7, REGISTER_8, TOTAL_REGS_SIZE }; unsigned int holdingRegs[TOTAL_REGS_SIZE] = { 0, 1, 2, 3, 4, 5, 6, 7, 8 }; void setup() { modbus_configure(&Serial, 9600, SERIAL_8N1, 1, 2, TOTAL_REGS_SIZE, holdingRegs); } void loop() { modbus_update(); }   Any answer can be helpful. Thank you for your time!   Regards, Jose.

  24. Hi, I want to sent simply frame using FB mady by JPV from Omron France. It should send just frame  01030FA60002273C  to slave #1 When I check Multiway - it seems that frame is OK, but slave no reply. I checked different soft to monitor serial port and frame looks different - some bytes are sent twice.  I attached   screenshot and you can see the difference - Can you explain why it happened. Both frame I got when I set W30.0 in PLC and I saw just one blink LED Hmm I also attached screenshot from my serail port configuration. I tried also diiferent set of CP1W-CIF11 dip switches, but the same effect. Any clue??? thanks in advance                 
  25. MODBUS Newbie!

    Hi Guys just a quick one before I begin thinking about a new project using MODBUS RTU i want to have a MODBUS network over RS485 consisting of a HMI (Master) FX3G (Slave1) and a remote IO unit (Slave2)    obviously  i I know the master can request information and send commands to slaves, but can Slave1 send outputs/commands to Slave2? Or can only the master communicates to each slave?
