  1. Hi! I would like to ask how could I send data from PC to CJ1M PLC, by SCU-41 module and RS232 cable, in order to activate an actuator (LED)? In my environment, I have a sensor that sends data from PLC to PC (I'm checking data, "HelloWrld" with Putty), with this configuration: And I have another section where I want to read the data from the PC in ordr to activate a LED I would like when I send for example a letter 'a' trough Putty, the LED activates. How could I do that? Thank you very much!

  3. HI All,  I have an issue with my SCU32 communication.  Back ground Two SCU32s  (top and bottom side) connected via a 1100M datacable  using port1 ( 9600bps,  8-2-E, start code FF, end code FE, Tx save to d1000-d1200 , Rx save to d2000-d2200). PORT2 of bottom SCU32 is connected to a compass( 2 wire, 8-1-N, 19200 bps, serial gateway MODBUS ). Refer to photo Issue  Without compass, the receiving data at top is very stable and is didn't see any fluctuation. But if is compass is connected at bottom side port2, there is a fluctuation at the top side RX data(specifically d2000-d2005 ) .  I checked the data a bottom side TX (d1000-d1200) and it is stable. Only after sending the data and Receiving at Top side, then only the starting words fluctuate. I am not sure sure what is wrong, I am using logical ports for the DTXDU/DRXDU and compass.   Appreciate all your feedback and suggestions.  
  4. InTouch Comms

    Hi Everyone, I've just installed InTouch V10 and am trying to develop communication with Emulate5000, for educational purposes. I looked over the internet and found some videos on how to develop communications by setting up the topic name and node name in DA Server manager, but the issue I'm facing is that my SMC only shows logViewer and nothing else (snapshot attached). Am I missing some vital component or dirver? Or is there some problem with my installation? Help would be much appreciated.   P.S: Window Maker and Viewer are working fine. Thanks, Sabih

  6. Hello there, I am new to OMRON so need some help to communicate two PLC over FINS.   Here are the description of the system... (IO Table image is attached)   PLC1-  CJ2M-CPU33 IP- 10.113.218.34 SUBNET-255.254.0.0 UNIT NO - 00 (set the dial available on the CPU in HEX) NODE - 22 (set the 2 dials available on the CPU in HEX) PLC2-  CJ2M-CPU33 IP- 10.113.218.35 SUBNET-255.254.0.0 UNIT NO - 01 (set the dial available on the CPU in HEX) NODE - 23 (set the 2 dials available on the CPU in HEX)     Now, what i have to do is to transfer the D100 to D110 from PLC1 to PLC2's D200 to D210 and Transfer the D100 to D110 from PLC2 to PLC1's D200 to 210.   I have tried RECV and ECHRD blocks but didn't succeed yet.   Two CPU are connected over ethernet via a industrial switch.   Can you help me to achieve data transmission please...
  7. Hi All need to convert a Decimal Value into Ascii code to send out on serial 485. eg. Weight comes in as Int 12345 i need to send it out in Ascii as 23 32 20 31 32 33 34 35. I have created an array 0 of 8 (Word) DB. Is there an easy way split the int into Digits convet in into HEX and slot the value into the various array positions? Array 0 of 8 = 23 means # Array 1 of 8 = 32 means 2 (Station ID) Array 2 of 8 = 20 means Space Array 3 of 8 = 31 means 1 Array 4 of 8  = 32 means 2 Array 5 of 8 = 33 means 3 Array 6 of 8 = 34 means 4 Array 7 of 8 = 35 means 5 Array 8 of 8 = D means CR    this sends the value of 12345 to Display ID 2 . need help to convert the decimal number in ascii. the decimal number will be max of 5 digits and less than 32000   any help will be greatly appreciated.
  8. Hey everyone, I have a CJ1M PLC with a CJ1W-SCU21-V1 serial card. It is unit 6 and I am using port 1. I have bit 1659.06 ((1500 + 25 * Unit #) +9, bit 6) as "characters in buffer" but it never comes on (data is being received through the port successfully). It is on No-Protocol mode. Does anyone have any ideas as to how I can detect data in the buffer?

    hi there. .. i am new to plc programming.. Right now i am having problem related to communication between hmi and plc.. i have HMI WEintek 6070ip and plc mitsubishi FX2n.. i have written a program in gx developer . and communicate it with EASY Builder for HMI. so for now plc is communicating with my program written for hmi on pc. but when i downlaod to hmi and connect plc cable to hmi then hmi shows no plc communication. i am having a problem for communication between hmi and plc. any help will be a life saver. thanks in advance
  10. Serial comm with FX1N PLC

    I need to communicate with a Mitsubishi PLC using Matlab. To do that, I open a serial communication with the appropiate parameters (7,e,1,9600), and write an ASCII message based on the manual I have (attached). I have tried examples as the one in the attached image. The response starts with a 6, that is, the ASCII number for ACK, so something must be working. But the rest of the response is junk (149, 149, 149...), although its length depends on the input length (if I add terminator, the response is longer, and so on). I am completely stuck. Some information that might be helpful: I am using a Serial to USB converter that I have used successfully with other PLC (which used Modbus, so everything was easier) There's a VB application (of which I don't have the code) that is able to connect to the PLC (I need to connect directly without using this intermediate app). I have decompiled it trying to get some info, but was just able to confirm the 7,e,1,9600 parameters, since the rest of the code is too mangled to analyze The attached manual was sent to me by the guy who designed the PLC and its ladder code, so I guess it is the correct one I have tried the echo mode (TT) to no avail, response is always the same I have some doubts regarding the reading of a value (see attached image). Why is there a second message from the PC? Shouldn't I just need to read the response? GX Developer tells me that the address D8120 (which is supposed to define the comm format and protocol) contains a 0, which seems weird. Any help or hint would be greatly appreciated.

  11. Hi everyone! I got this machine with a CP1H PLC and NS8-TV00B-V2 as PT. I was told that they were working fine, but suddenly, It appeared a communication issue: black screen and "connecting..." at right bottom. I dont know if It is a configuration problem or some hardware damage.  These are the configuration in the PT and the PLC. The communication is through RS232 Serial.  I tried to communicate another PT screen with the same communication settings and IT WORKED!. ' I've been thinking that, perhaps, the serial port A is damaged, I have tried to set port b, but I havent could. How can I configurate PORT B??   THANKS...  
  12. Hey all - I am working on a car wash system design that will utilize the Nayax payment system. Has anyone utilized them? How do I incorporate the device with PLC to automate the system. After payment is approved how can I send out that signal from them, all via ethernet on a managed switch w/ wifi for exterior comms for the Nayax.
  13. Hi All, Hope you all doing well in this pandemic life.  I would need your expertise with an issue I have been struggling with for past few days and thought to reach out here. I am working on a migration project with GE PLC and Citect SCADA 7.10. The GE PLC is migrated to ControlLogix L74 Rev24.10 while Citect SCADA is retained. For testing I only have L71 and L82 and could not managed to organise L74. When the code the loaded in L71 and connected to Citect, I cannot see tags in Graphic page but I see the subscription.txt in Debug folder shows all tags good . The same code when loaded in L82, the Citect works instantly.  Does anyone know this behaviour of PLC and SCADA? Regards, DeeEngr    
  14. Sorry for my bad english speaking. I want to change the baud rate to 19200,38400,.... for send it via Programmer-Serial-Port. The software GX-Developer can do it!. When the PLC is switched on, we generate a value in the data register D8116 and D8117. GX Developer reads the PLC type and data registers D8116 and D8117 at startup and generates a value. This value is written in D8118 and D8119. The big question is: how is D8118 and D8119 generated ??

  24. Connect PLC to Kepserver

    I have Delta 12SA2 PLC it has RS232 port and I have connected it to kepserver (by Modbus serial) and then factory IO Now my problem is that when I connect my PLC to kepserver the RS232 port becomes busy with the kepserver and not available in the ISPSoft and therefore I could not demonstrate factory io and my logic in run mode in the isp soft together like you do in your videos. My PLC don't have ethernet port but is there an option in kepserver or any way by which i can use the same serial port of the PLC in isp soft run mode and kepserver+factory io together so that I can simultaneously show the logic running in isp soft and application working in factory io to my students. I googled a lot and found some softwares which make virtual serial ports for a given serial port but they don't work and soon hang Please help me I am in a great need of it. Thanks in advance.
  25. Hi All, Am trying to communicate and make In-Sight bar code reader to trigger through MicroLogix 1100 with RSLogix 500.  Does any have any info as to the steps to follow.
