  2. Hi all, I am having some trouble communicated with a Omron CP1H PLC from CX Programmer.  The CP1H itself comes with two option boards (CP1W-CIF01) to allow for communications via RS232.  The PLC also has standard USB access. When I connect my PC (Windows Server and Windows 10) to the PLC via USB connection I am able to communicate successfully.  The only caveats are: The PLC program appears to be read protected (not related to USB I assume!) The system which I want to integrate the PLC with, Kepware Server, does not appear to support OMRON usb communications. Kepware Server does have support for connections over serial or ethernet so I am looking to make a connection via RS232. After some digging I realised the RS232 cable needed to connect the PLC to a PC is not your standard cable.  I purchased the XW2Z-200S-CV RS232 cable and tried it in both option boards but CX Programmer is not able to make a connection. I used the auto-online, serial port sniffer and manual configuration.  I must have cycled through all possible combinations of settings several times but no joy. I can see an led light on the option boards flicker when CX Programmer is attempting to connect so it appears that something might be happening.  One of the option boards is already occupied by another device (which is working) btw.  I did unplug that device and tried my own cable, again, no success! I also double checked the cable itself to make sure the wiring was working correctly, it appears to be fine. So my question is, does anyone know why the RS232 method is not working?  Are there any options and settings I need to check?  Perhaps I'm missing something obvious. Thanks!  
  3. Hello, I am trying to receive data from a scale via rs232. my setup; compact logix l18er with a 1734-rs232ascii point IO module to receive the data. I am receiving data from the scale, but I have very little understanding of ascii, so I do not know how to convert the data I am receiving to something use-able. any help on how to convert the data to something I can use or where to even start would be much appreciated. using a scientech ZSA 210 scale https://scientech-inc.com/media/downloadable/files/links/1/2/12222-d_rev-f_instruction_manual.pdf

  5. 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.

  7. 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.

    Hi dears i have one cp340 (340-1AH02) that is modbus RS232 RTU master and one RS485 RTU slave. i want to use RS232 to RS485 converter is it ok? can i do this without any problem?
  9. Hi Im hoping someone can help me out! i have a PLC SLC 5/03 and i want to connect the DB9 port with DH485 protocol to a computer 100 fts from there, is there any problem with the distance? and what kind of cable should i use , i already connected with my laptop with a USB-serial with a null modem cable RS232  (i did the cable by my self) but for the distance i cannot keep using that protocol so what is the recommendation?    
  10. Hi i have Beckhoff (CX5020-0120-M310) (profibus master) with TC3.1 and want communicate with Siemens Profibus ET 200S (IM151) DPV1. All modules works on ET200s except 1SI RS232 (6ES7138-4DF01-0AB0). When i triggered Barcode scaner i have one bit ON on no more data from 1SI module. on Array (0..15) of words 0.#0000000000000000 1.#0000000000000001 <= this bit is ON after trigered pushbutton on scaner 2.#0000000000000000 3.#0000000000000000 ..#0000000000000000 ..#0000000000000000 15#0000000000000000 This Same ET200S with this same configuration i have tested with Siemens S7-300 and it works, i can read data from Barcode scanner on the 0..31 array of byte (no WORD's like on CX5020) Siemens have On Communication => ET200s serial interface => Function block S_RCV i use them and i can communicate with 1SI RS232 via this block. But Twincat 3,1 don't have this block. On ET200s i have: 1. 1SI(rs232) module (rs232 parameter is : Data - 8bit, Stop - 1 bit, Parity - NONE, Data Flow - NONE, Interface type RS232-C ) 2 DO modul 3 RTD modul 4. DI 5. RO modul Any ideas where are problem? why can't read data from 1SI RS232?
  11. Hello At first - sorry for my bad english. I have a FX2N-48MR with a FX2N-232IF and i only want to watch the X and set the Y over RS232 with a Crestron Contolunit. I use GX Developer 8 on a XP Laptop and figure slowly out how it works. 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
  12. 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!
  13. I'm wanting to get upload the program from a CompactLogix L31 Controller.  I'm using a generic (non Allen Bradley) "C2G brand" usb -->rs232 cable coming directly off of my laptop because I don't have a serial port out.  The rs232 side of the C2G cable is a "pin out" or male end, and as you can see in the picture, the serial port at Channel 1 on the controller is also male.  I'm using a generic (non-Allen Bradley) null modem (female-->female) cable to complete the connection.  Ultimately, I'm not seeing the controller on linx.  But that's a result of me not being able to configure the driver.  When I try to auto configure this driver, Linx gives me an error saying, "Unable to verify settings due to a NAK!" btw, the rs232 cable going into channel 0 is for the HMI on the machine. A pv600 1. How do I get online and upload the program from the controller? 2. What does NAK mean?
  14. 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.
  15. OMRON CP1L PC Link over Bluetooth

    Greetings, My application is utilizing two Omron CP1L PLCs connected through an RS232 serial link to achieve PC Link. We're essentially using this setup to message data between the two PLCs. With a hard-wired link, it works great. I can force bits in the master PLC, and see them in the slave PLC. However our application requires this link to be wireless. We got our hands on two SENA Parani SD1000 units. I've worked with these units previously to connect a serial scanner to a Rockwell PLC quite successfully. After reading through datasheets, we figured out the pin-out from Serial Comms unit fitted to the CP1Ls wasn't quite standard. So we adapted our own cables to re-route VCC and SG appropriately. So with a hard-wired link, this setup works, and the comms units on the PLCs have a nice solid lit up comms light. But with the wireless parani connection, the comms light lights up, but it is very dull compared to the wired link, and we get no data transfer. I've verified to the best of my understanding that the comm settings all match, at 9600 Baud, 8 data bits, 1 stop bit, and Even parity. Just curious if anyone has any suggestions to get this working, or if there are any settings that I might have missed that make PC Link a unique form of RS232 that these parani units can't handle? I've identified online alternative units known as the Promi SD205-OA, which has a pin-out to match the OMRON CP1L PLCs. As far as I can tell though, the units themselves function the same as the Parani SD1000 besides this pin out. Anyone know differently? Presently the serial connections made are Tx -> Rx, Rx -> Tx, Vcc -> Vcc, and SG -> SG. Would I require anymore connections? Our wired link seems to work just fine with just those connections.   Any help would be greatly Appreciated!!
  16. CP1E-N30DT with Hyperterminal PC

    Dear Expert, i'm issue to do communication CP1E with PC via RS232. im try to use plc for sending information and receive by hyperterminal pc. after googling some information there have multiway to success. by the way until now cannot settle. please expert share completed setup that's work: 1. communication cable from PLC - PC (my information use pin (2,3,9 jumper 4&5) - (2,3,5 jumper 7&8) 2. sample program that works (im using TXD & RXD with memory D1000 to keep data) 3. connection cable to PC using MOXA Serial to USB converter. 4. plc serial setting (default: 9600,7,N,1,Host link) my target to give instruction to printer to start print. printer need ACSII code. if this communication success i'm will convert all data to ACSII by ACSII convert function.   thanks,
  17. Hi everyone, I'm trying to connect a computer to a SLC 5/04 via the RS232 interface without success. The same module has been running and connecting/programming via the round DH+ connector just fine. So when I start it up now, I can put it into run mode, DH+ LED blinking. The problem is I can't establish the RS232 connection, first time ever I work with a PLC... I've used two different computers with RSLinx and RSLogix500 installed, one with a proper COM port, one with a USB adapter. When I define a new driver in RSLinx the Auto-Configure gives the error message in the attached picture. I'm using a standard COM port cable plus a F/F gender switcher. Both checked with a multimeter, no twisting or switching of contacts going on. One problem is I don't even know if the RS232 LED is supposed to be active as soon the cable connects the PLC and the computer, or only if there is an active data transfer. So I don't know if the actual connection is at fault, or if I'm doing something wrong in the software.   Any tip would be greatly appreciated!   Volker

  20. 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.
  21. Hi all, I have a micrologix 1400 plc and an SIC E10 engraving machine. the engraver requires its marking info ( day/year/random sequential number etc) to be sent to it via rs232 connection. the manuals have nearly melted my brain and I have no clue how to convert and send this type of info via rs232. please help.   thanks       NOTPROTOE10V6US-R04.pdf
  22. I was wondering if I can use the ethernet and the rs232 interface at the same time with two different devices. A computer with RSLinx on the ethernet and and Arduino RS232 on the RS232 with DF1?
  23. 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.

If I want read CIO 10 i sent: "0101B000000A" ? and FCS and "*" ?? how i calculate FSC? Is it XOR my data sent? 
  25. GS2107-WTBD and rs232 input

    We are upgrading our A900 GOTs (finally) and I'm looking into updating our key switches to rfid readers. Does anyone know of a good rs232 rfid reader to pair with a GS2107 GOT Simple? Also if anyone has had luck with scripting for security levels and could post a sample (be it GOT1000/2000) it would be awesome sauce.
