  2. connection to omron CJ1M PLC

    I have an omron PLC (CJ1M type) at home which I would like to connect to, however, lately, I can't anymore.  I'm trying on two different PC's a newer and an older one, both running on windows 10. 1 is just mentioning a DLL error and I can't even start cx-programmer, the other one seems to work, however, when I try to go online it always fails I'm using a usb to serial device and after some searching on the net, I thought the issue was with the prolific driver.  I tried all kind of fixes, but nothing seemed to work.  I have now purchased another device, the XS8801 from usconverters and installed the latest driver.  I have checked if cx programmer is set to work with the correct port and this is the case. My knowledge is very limited but I would really want to connect to that PLC again, so hoping someone out here is able to help me. Thanks a lot    
  3. Check serial connection to Omron PLC

    Hello, I am building an application in CitectSCADA and I want to communicate with an Omron Sysmac CS1G. The connection between the plc and the Citect computer is through an ethernet to serial adapter (the computer doesn't have com ports on board). I'm having some difficulty establishing the communication and I want to make sure that I can actually reach the plc. Is there a way to check that the computer can reach the plc over the serial connection without using CX programmer? Maybe using Hyper Terminal, Putty or something similar. Thank you, Liron

  5. 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!
  6. 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.
  7. 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?
  8. 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. Thanks jy992d69901e.pdf
  9. Dear all, I had bought a mitsubishi plc fx3s-20MT/ESS which is the source output and I plan to try to send pulse to Mrj3a Servo Drive. According to the manual, it stated that the servo drive able to support the source type plc but I do find out that manual also mention that only sink type plc is suitable for melsec servo drive.  Anyone can help me in this case?

  13. 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.
  14. Hello, I have been so many days trying to comunicate the multiway software trought a serial usb converter with the SCU31 device, using a omron function block to read a holding register, but I can't achieved it. Now Im receiving some frames on multiway, but there is always some errors. I was wondering if somebody in here that have worked previously with modbus and omron can be able to help me in how to configure everything corectly to be able to read the value from multiway, on the plc, and where is this value saved.  I'll upload some captures to show what I have done till now.

I read the manuals i found, managed to send from the PLC to the Serial Program on my Laptop (Program named HTerm) But i do not figured out the sending. Can you give me some hint?   Greetings FT
  16. CJ1M serial communication

    Hi! I would like to know how I could send information throw serial RS232 communication. I mean, I have CJ1M-CPU11 connected with ID232 and OC201 modules, and I have an optic sensor (digital input). When the sensor turn on, I would like to be able to read the information (on/off) with an application like Putty (I have the PLC connected by RS232) to develop an application and show the information on another framework. I don't know if I have explained very well. Thank you!
  17. HI ,  Thanks a lot for the reply & help on previous topic. Now i setting up a new system with 2x CJ2M CPU13  and 2x SCU32 and the connection via 1000M RS485 cable. May i know the best communication to use for the serial communications?   Regards, TJ SHARON.

  19. 90 30 CPU350 serial connection

    ok running into a issue here, so we were able to communicate with the processor to download a program. transfer went fine. upon cycling power, we can no longer connect to processor. we used LM90 for the software. i've tried removing the battery and shorting out the "mem clear" points on the board, however we can no longer communicate with the CPU. we have a POWER and OK light solid on the power supply. kinda stumped here if anyone has any insight.
  20. Is it possible to use FX3U-485ADP-MB as a serial port to send and receive user defined string/data to and from a computer? I have a FX3U-32M PLC and two FX3U-485ADP-MB adapters. I have been using PLC with one adapter as Modbus Master. Now i want to use both adapters, where one will be Modbus Master as usual and the other I want to use to send and receive data to and from computer terminal (Example - Realterm). I have a third party 232/485 converter which works really well. Lets me just describe my requirement straight forward. I want to display process parameters on a windows computer based user interface (UI) and also set some variables in PLC from the same UI. The UI has access to serial ports of computer.

    Hello, i'm newbie for plc. i want to ask about PC/computer send data to PLC CP1E with serial communication (RS232). my wiring cable is: PC                         PLC 2                             2 3                             3 5                             9 4&6    7&8                               4&5 and if i send data from PC to PLC, my indicator in COMM is blinking. i think the cable have no problem. but if i send data from PC to PLC, the memory is not same as what i send and whatever i send data, the memory didn't change. i will attach my ladder diagram. what should i do?    New folder.rar
  23. FX3S not responding to HMI.

    Hi guys, I am an Electrical engineer on a cruise ship. I have a mixer (galley equipment) that is controlled by a FX1S-10MR PLC. It uses HMI F930GOT-BWD-E. Recently we found the PLC to be malfunctioning and replaced it with a new one from our stock. The new one is FX3S-10MR. Now, when i try to increase or decrease the speed via the HMI, the PLC doesn't respond; infact, the inverter just maintains a single frequency. The PLC is "supposed" to be pre-programmed by the manufacturer of the Mixer. I have very less knowledge of PLCs and sorry if i come across as stupid. I have been reading a bit lately. Do you think it would work if i can copy the program (from the FX1S PLC of another working mixer) by using GX works2 / GX developer software and write it on this new FX3S model ? What will happen if i change the type of PLC of this FX3S model to FX1S (just speculating since it's working find with FX1S). Today i tried to view the program inside this FX3S plc on GX developer and it does have a program. I am clueless though why it's not working with the HMI. Kindly, provide me with some guidance. TIA.
  24. Hello every one. I have three FX3U plc needed to be communicate over a wireless network. I'm using serial adapter FX3U-485ADP. I got E-byte data trans reciver E-30 for wireless communication. Now need help to setup the whole thing. Previously the PLC's serial connectors were connected through a flexible bus but when the platforms are running fast there is interruption in the  communication. So we want those PLC's to be connected over wifi.  Thanks in Advance 
  25. Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form.   http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.
