I have an application where I'm using GOT2000 to read data from the weighing unit using RS232 and I send this value to Omron CJ2M through Ethernet/IP. Some variables from that PLC are connected to the elements of the HMI. The problem is when writing the weight value to the PLC through script or Data Transfer is disabled, the RS232 reading works fine, it's fast, etc. However, when I enable the script which writes data to the PLC, the RS232 slows down by a lot, like it refreshes every 2-3 seconds. If i set the script to execute like every 1-2 seconds, it is working better (still slower compared to when the script is disabled) but I cannot leave it like this, because the weight is used to control some valves, pumps, etc. Enabling script doesn't slow down normal communication with PLC, because I tried to test it by displaying the value of seconds from PLC on the HMI and it refreshes every second. Does anyone have idea why such tiny script causes so many problems with RS232?

Hi all,I'm completely new to ASCII and trying to figure out where I'm going wrong here.Application: I need to send 2d barcode data to a KGK Jet model CCS3000L Inkjet printer. Only protocol possibility is ASCII. PLC I have is a Micro850, and the only port option for ASCII is the serial port. I modified one end of a 2707-NC11 cable to connect PLC TxD to printer RxD, PLC RxD to Printer TxD, and PLC SG to Printer SG. I jumpered CTS and RTS at the printer connector, and the 2707 cable I'm using doesn't have wires on the Micro850 CTS or RTS pins.Printer company verified that I can just jumper RTS and CTS on their side and not connect their DTR and DSR pins (since I'm not using hardware handshaking). I don't really need any flow control for the application ( I don't think...again, ASCII noob here).Do the CTS and RTS on the PLC side need to be jumpered? Does the DCD pin need to be jumpered or connected to something if I'm not using handshaking?I downloaded the Micro800 ASCII read and write functions and function blocks from Rockwell library, and they seem to be working, except that I keep getting ABL error id "7". This error states, "Cannot complete ASCII send or receive because channel configuration has been shut down using the channel configuration dialog box." I have the serial port enabled and configured to ASCII, no handshaking, baud 9600 same as printer, no parity check, 1 stop bit, character length of 8.Any help in pointing out what I'm doing wrong or things to try would be greatly appreciated!

Hi, I have a CP1L and CP1E Omron PLC, and I try to make communication between my PLCs and my system (raspberry pi with Linux OS) using Node-red and specifically using the OMRON-FINS node ( https://flows.nodered.org/node/node-red-contrib-omron-fins) and more detail ( https://github.com/ptrks/node-omron-fins ). So I’m looking for a module to create an Ethernet port for my PLCs. ( both PLCs have RS232 port) . Can you please guide me to find a compatible RS232 to Ethernet module for my PLCs? Thank you

Hello, I've been using Mitsubishi and Omron systems separately (in their own environment), and I am fairly new when it comes to connecting these two brands together(plc and hmi). I've been scouring the net for wiring diagrams for the cable connections and also the parameters to be set for a successful communication between those two components. can anyone point me at the right direction as everything I've tried so far has been a failed attempt of making these two communicate. here are the parts and my current settings if this helps: FX3U-64M FX3U-232-BD NB5Q-TW00B or better yet, is there a proper cable that I need to buy for this to work?
-
I have successfully downloaded the HMI program into NB7W-TW00B, but there is no display on the HMI because the communication indicator which is connected by the RS232 cable doesn't light up. I have verified the wiring and pinout of the RS232 communication cable. What else can be done to troubleshoot this issue? -
Hi there, I am fairly new to programming serial communications, especially with Mitsubishi PLCs. Can someone walk me through in ladder logic how to bring in ASCII to the PLC, store the data in the data registers. Then send the data out to another PC once an 'X' input is satisfied? ASCII code would go like the following: C2,0,1,123,2,ABC,3,456,CR

Hello Sir / Ma'am, How to connect Omron CQM1H-CPU21 (Image Attached) to the software for Configuration. I have tried it many times but I think I am missing something from the wiring side. Above mentioned Controller has a built-in Peripheral Port and an RS232 Port, We don't have that particular cable that connects the Controller to the Software via Peripheral Port. Kindly help me to connect the controller using the RS232 Convertor. I am using ATC-810 RS232 to USB converter. (Image with all Pin Details attached) Software - Syswin or cx-programmer.

I have an SLC 5/03 that Im trying to get the program from. I have a 1747-uic. Im not getting anything to show up in rslinx and I suspect the channel 0 is configured for ASCII because theres an HMI plugged into it. Also the rj45 connection is broken because someone used a crossover ethernet cable...lol. is my best bet to try and fix/replace the 1747-uic? I have an offline copy of a program from a different machine that uses a 'similar' setup and the CH.0 -System is configured for DF1 full duplex,19200,CRC and CH.0 - user is ASCII 19200 baud. Any Ideas? I was using the 3 wire db9 connector running from the HMI to the PLC. I unplugged it from the HMI and used it with the 1747, Should I use a standard DB9 cable with a null modem adapter?

Hello All, Semi-noob here with Mitsubishi PLCs. I'm starting a project in which we are upgrading an existing A Series PLC with the Q. Is there a datasheet somewhere that lists compatible software within Mitsubishi's lineup? I had no luck in searching their site. Also, (in the same project) the existing network uses DeviceNet. I have the Q series compatible card for that - but within what software does one configure the network? Thank you.

Hello All, I have had no luck sorting through Pilz datasheets on this CPU to find cable / software to connect/upload the program. Any insight? We are upgrading this to the CPU 4000 series - it will use DeviceNet. Will this node number / memory allocation be setup within the 'PSS 4000 Firmware' software? Where do I find a guide for this? Thank you.

Has anyone interfaced an SR1000 (or similar keyence barcode reader) with a (Automation Direct) Click PLC? I am looking to read/write rs232 so I can get the string back from the barcode reader, instead of actually teaching it or using banking (banking is a bit cumbersome with the keyence, plus it'd take me a long time to actually get the labels I need to teach the camera all). I had started messing around with the application, but I have no way of seeing if the camera or plc is actually reading/writing the data. Data is all ascii. Thanks,

Greetings everyone. I'm new here. Hoping to get help to operate the Omron V400-R2 barcode to the Mitsubishi QJ71C24N so that they can communicate the two devices with the correct method. PLC: Mitsubishi: Q03UDVCPU; barcode: Omron V400-R2; serial communication module: QJ71C24N. I use RS 232 communication cable, I have tried using predefined protocol and non protocol procedures but still can't communicate the two devices. I really appreciate your help.

Hello, I need to connect multiple barcode readers (SICK CLP510) to a PLC (FX3GE-40M) for a university project. I need a minimum of 3 bar code readers, but only have one operational, connected via an additional modul for the use of rs-232. The only other port I can use is a miniDin 8, which is a build-in rs-422 port. Because this is a university project, it needs to be as cost efficient as posible. All the readers are CLP510 (pin-out attached bellow) Thanks Becky Pin_out___wire_colour___signal_comparison_CLP100_CLP510_CLV60x.pdf

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 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!

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!

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?

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!!

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
