Hello, I seem to be having trouble reading comments from PLC in GX Developer. The PLC is an ACPU, Everytime I try to read comments using GX Developer I get the following error. "The comment was not read correctly". I found an old project from this PLC that has comments, But im unable to read any current ones. Anyone experienced this before?

Hello, I was wondering if any of you have experience translating comments. To be more specific, I have been tasked with translating all of the comments in my plant from japanese to english. We have many different series of PLCs, but they are all mitsubishi, and I will be using GXWorks 2 for 99% of them. I had the idea of writing the comments to a CSV file, Translate them there, and then just read them from CSV back into the project. I have tried numerous methods, but it seems the CSV loses format and isnt able to be read back into GXWorks. Some of these comment files have almost 10,000 comments. Do any of you have any suggestions on the best way to translate these comments over, in a more automated way than manually one-by-one. Thanks in advance for any support you can provide!

Hi everybody; could you please help me;i would like to learn how to convert a sinwave signal with analog input of my R60ADV8 module.How many samples should i convert ? what is the maximum frequency of the input signal? and how to recover the sinwave signal in the analog output of the R60DA4 module? i can convert dc signals from sensors and recover them in the analog output;but i have no idea how to do with sinwave signals. Sincerlly yours

Hi,I am connecting several computers and NS12 HMIs with a CJ2 PLC using EtherNet/IP protocol. And I would like to know the FINS Address (Net.Node.Unit) of the HMI and the computers. I suppose I need to fix their addresses using an IP Address Table. Right?? Anyway, I only know to do that with UDP, but I don't know how to do that under Ethernet/IP.Thank you.

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

Kinetix 300 Ethernet/IP Locks Up
Glenn Robinson posted a topic in Allen Bradley / Rockwell Automation
I am trying to use an Automation Direct Productivity P2000 to control a Kinetix 300 servo drive using Ethernet/IP. I got the EIP working fine using Explicit Messaging. The hardware enable and overtravel limits are hardwired ON. The drive doesn't show any faults. When I turn on the software ENABLE bit (bit 7 of byte 0 in the Output Assembly), the Ethernet communication stops. Motionview continues to work, but if I disconnect and reconnect, it can't find the drive. I have to physically power down the drive to reestablish Ethernet communication. Once I power back up, EIP communication resumes with no issues. Any thoughts? What am I missing? -
Hi all, after my complaing about my lack of network access in the workshop ive been tasked with fixing this so ive have some general questions about networking and concerning Ewons so this network will be used for connecting ewons to test products as well as general computer access the plan is to have 7 computer access points as well as 2 points to connect to product lines for testing my intial thoughts were to run 2 cables from our network to 2 routers, 4 computer access points and one line testing connection on 1 and 3 computer access points and one line testing connection on the other so first question is what type of ethernet cable should i use? i assume cat5 is fine, is it worth going for cat6 or is it just a waste of money? and should i be running crossover cable or straight through? do i need any specific routers or will anything do? will i be able to add splitters later down the line and be fine? or should i future proof a bit with more robust routers? my years of avoiding networking at uni has come back to haunt me i know the basics but thats all really thanks to anyone who can offer some usefull information i mention the Ewon units because ive been told that they need to be the only one on their connection to the network, although i dont know how true this is

We have an application using a Mitsubishi L02CPU-P with a built in ethernet module. At one time the TCP/IP interface became irresponsive and a hard reset was required. The device is configured for binary communication and works fine using a GOT therminal and also operates fine when queried from a GX Works application. During debugging of a custom MELSEC application the TCP/IP interface stopped responding and could no longer be located using GX Works and the GOT terminal also lost contact. The L02CPU-P continued running the control application, but could no longer be contacted. The only way to recover was using the L02CPU-P reset button. I have heard developers being restrictive using the TCP/IP interface remotely over VPN and unstable connection due to the risk of hanging the device and not being able to recover without a personal visit to the device. Any experience from L02CPU-P devices requiring hard reset to come "online" again? Or does it enter some default state due to some internal exception handling?

Hi to everybody. I'm beginner on Beckhoff so I'm having issues with connecting Beckhoff CX8090 and Weintek EMT3070a. I'm trying to use Beckhoff TwinCAT PLC Free Tag names to get data from CX8090. I have followed instructions in EasyBuilderPro which are pretty straightforward. On side of HMI I need to select proper settings which should be: IP: 192.168.1.2, Port no.: 48898, ADS port: 801, AMS NetID: 192.168.1.2.1.1 I have succesfully imported all variables from my PLC program into the EasyBuilderPro. For testing I tried to create HMI just to see status of few inputs. I have no issues uploading program to HMI, but after startup I get message Device no response and communication is not working. On side of Beckhoff I have settings like this: AMS NetID: 192.168.1.2.1.1 Ethernet port X001: DHCP Ethernet port X101/102: IP: 192.168.1.2 I can access to CX using input ports X101/102 and also access to HMI through same connection. I have also tried to log on to windows CE on CX and tried to ping HMI and that also went ok. Also I have tried to add static route on TwinCAT to HMI with settings AMS NetID:192.168.1.3, IP:192.168.1.3 but again no connection. So physical connections are CX8090 X101 - > HMI, CX8090 X102 -> PC. From PC I can access both devices. I'm using TwinCAT 2. Can you tell me what I'm doing wrong? Thank you

Micrologix 1400 Lookup Table over Ethernet/IP
cekann posted a topic in Allen Bradley / Rockwell Automation
My project is to read an RFID tag (ascii) with a Micrologix 1400, send the string to a PC using Ethernet/IP, lookup and compare in an Excel spreadsheet, and send back data (probably an integer) for the plc to use to control direction. I have to scan and compare an RFID tag to a list of 1400 possible part numbers, at different locations (more than 1 plc). I want the several PLCs to go to a single PC to make it easy to update when changes occur (on a weekly basis). Has anyone done anything like this? I'm assuming there will have to be some kind of vb or c+ application involved. Thanks, CK -
Hi everybody, Is it possible to send MELSEC commands to oneself, locally, not using the phiysical ports? I would like to use some commands described in the "Communication_Protocol_Reference_Manual_(MELSEC)" to get some self-management functions in my PLC. For example, in OMRON this is possible using CMND instruction and setting the FINS address to 0.0.0 in the parameters of the instruction. Thank you very much.

How to connect Mitsubishi PLC with QJ71EIP71 and SICK FLEXI soft Ethernet/IP
Wasan posted a topic in Mitsubishi
Hi everyone. I have project to use PLC Mitsubishi Q03UDECPU with QJ71EIP71 to connect with SICK FLEXI soft Ethernet/IP (FX0-GENT00030). I have check both manual but when I turn on Y0 (communication start) there are error code F100h on my QJ71EIP71 and I check that it can only use with produce/consume tag from PLC (such as OMRON, Allen Bradley) but for SICK device it can use only for assembly instance. Then I have use Ethernet/IP scanner (Molex) to read attribute (service code 72h) then I can read status from SICK but as I told before QJ71EIP71 can only communicate with tag-based. Then I have to ask everyone that 1. Are there method that can use QJ71EIP71 to communicate by use Assembly Instance? 2. Could I set consume tag name on FLEXI soft Designer? 3. Are there any protocol gateway device that match with these solutions? -
Configuring high speed counter card 1734-VHSC24/C with explicit messaging
Jiggadoo posted a topic in Allen Bradley / Rockwell Automation
Hello! I have a problem with Allen-Bradley High Speed Counter card 1734-VHSC24/C. I need to make changes to the configuration parameter .OnValue1 (DINT) during the system is running. Now, for changing the parameter value, I need to switch off the module and this can not be done during the line is running. I think that maybe this can be done using the explicit messaging. I could not find information for this from internet, so now I ask you to help me with this item. If anyone have experience or knowledge of this, please help me. I do no have experience using explicit messaging. My configuration: Studio 5000 Logix Designer V24.00, 1756-L71S V24.11, Ethernet/IP, 1734AENTR, 1734-VHSC24/C countermodule. -

To all the gurus. We have a project now that is using CJ2M PLC. However some hardware is using 1 piece of ETN21 card while some machines are using 2 cards. Programs sequence is quite similar. However Customer wants us to be able from program side able to detect if there is 1 card presence or 2 cards presence. Not sure if there is certain bits or memory in PLC that program can tap to "detect" number of cards that is presence.

HiI am just starting out at a new job full of GE systems.I have a IC695ETM001 ethernet card which has a RS232 port for Station manager access.I can currently see some info (such as IP, firmware version etc.) from the card when I connect with Putty and cycle the power but I cannot send commands to the card. I've tried Putty, hyper-terminal and a standalone Station manager terminal from GE but nothing works.Anyone know whether I'm missing something?

Hi ~ Thank you for helping me I use the Q03UDVCPU this time. I set a TPC MC Protocol 3000 port on the Built-in Ethernet to give PC to connection. The ethernet cable configuration is the PLC CPU link to Switch and link to PC. The problem is that when the PC is connected to the PLC, I use the Ethernet diagnostic of Work 2, you can see that the port 3000 is occupying by PC. There is no problem here, but when I remove the ethernet cable the PC, this 3000 port should be cleared, but the IP still occupying this 3000 port, until I remove the PLC CPU ethernet cable, it is the same result, and my PC can no longer be reconnect. Since the ethernet cable are all removed, the connection status should be updated, I don't understand why it is still occupying. Does anyone know the answer? Thank you so much!

Omron NX102 / NX1P2 cannot trigger MOXA ioLogik E1212 Outputs through Ethernet/IP connection, But I can read the Inputs Status All the time. Just CANNOT trigger the Outputs signal through Omron PLC. Moxa claim that they can use AB PLC trigger E1212 outputs and no problem at all, but now OMRON PLC cannot. Steps I am doing... Define the custom Data Type Structure. Create a variables with custom data type. Mapping with MOXA eds file setting. Inputs - 67 bytes, Outputs - 1 bytes. I had Install the MOXA EDS file I do contact MOXA Support channel, they claim that Omron PLC not response to port 2222 . Can anybody help ? because same Omron PLC using for test also tested with other EIP device with no problem at all. I have no idea which party are problem now... T.T
