Hello, Just recently bought a used CJ2M-CPU33 Omron PLC and I am trying to hook it up via ethernet. I keep getting an error F3. I figured it was because I didnt populate my I/O table so I did that and still no change. I have tried to connect to it via USB (which works fine) and then upload it a new IP address but no luck. Communication problems are my enemy and any help would be appriciated. Its a CJ2M CPU33 with a PA202 power supply. Analog in and out, digitial in and out cards. Thanks

[newbie] help regarding modbus communication
Siddhesh posted a topic in Allen Bradley / Rockwell Automation
I need help regarding setting up modbus communication between Allen bradley micrologix 1400 and Schneider altivar312 vfd and rslinx for pc. I am totally stuck with it. -
Hi Has anyone got any real life experience with the new Mitsubishi iQ-R series? I have been assigned a major capital project to replace our old ageing DCS system. Our current PLC backbone is about 40x Q2ASHCPU, 10x Q06UDEHCPU and about 2xA2SCPU all linked up via Melsecnet/10 network with communication links into the DCS system via Modbus RTU utilising the QJ71MB91 modbus card. Due to the nature of my companies process and the limitations on plant downtime it is estimated this project could take up to 5 years to complete, with this in mind I am wanting to install a system that will not be obsolete (or unsupported) in a few years, hence, I am very interested in the new iQ-R series with it being Mitsubishi's latest and greatest. However, recent communications with my local Mitsi rep is not filling me with confidence that the iQ-R series is not as well supported/developed as the Q series. A major requirement during the development stages of this project is the new ability of the new processors to be able to talk to the old DCS up until a point where the DCS nodes will be completed removed and replaced with a modern SCADA package. Hence, the requirement of a Modbus Slave card for the iQ-R (i.e. a QJ71MB91 equivalent) which I am told is in development, but has no fixed timescales. Previous experience with Mitsubishi developments of cards is normally years not months. Any information anyone can provide on their experience of the iQ-R series would be greatly appreciated and if anyone knows if a Modbus Slave card is in development that would be useful. I realise i could utilise the Q series extension rack with a iQ-R processor but this is not the route i want to go down. Thanks for any help and apologises for the war and peace. Cheers Matt

FX5u to FX5u Ethernet inter-connection (For data transition). (PLC to PLC communication)
RV3.0 posted a topic in Mitsubishi
Good day I require some assistance with the configuration setup (GX Works 3) for FX5u PLC inter-communication (PLC to PLC), over Ethernet (using the built-in Ethernet port). The purpose of the inter-connection is data exchange. (Values stored within the PLC storage registers such as words and bits). Does anyone perhaps support files on this such as a procedure or example? Thanks -
In general, this control PLC program is written in GX Works. I did a simple visualization on TIA Portal v14 (WinCC RT Advanced) and I would like to now test it on Mitsubishi FX3U driver with ENET Module. I do not have much experience in this kind of thing, I'm still learning. I know that someone previously made a visualization in LabView and downloaded the tags from the PLC using NI OPC Server. Someone also did visualization in iFix and also downloaded tags through server opc. I do not know just how or what program to download tags in PLC so that I can no longer use it in visualization in TIA Portal. Unfortunately I still have a connection problem. The driver is connected to the router. From the connection options with RT Advanced I chose in the connections tab Mitsubishi and entered the appropriate IP. Still nothing. I do not know if the lack of a connection can be related to a virtual machine (VM Vare Workstation 12) on which I have TIA Portal installed. The driver pings but can not connect. I also tried using KEPServer EX to connect and unfortunately also failed. (I have information about the can not connect). Anyone know what program I should use? or had contact with such a problem? I attach a photo of communication from my station to more visualize the problem. Thanks

Intermittent communication loss with rack/PLC
bboytaktix posted a topic in Allen Bradley / Rockwell Automation
Good afternoon fellow members,I once again ask for your help to know if any of you have struggled with similar issues. For the past year and a half, Every 1-2 months we seem to be losing communication with one of our PLC's/racks. We have in the rack a 1756-EN2T card (revision 3.006) that will flash as if it is communicating and status OK (green LED), yet we will be unable to ping it and our operator interfaces go into error. We could also not open the web browser page of the EN2T card, nor connect to the PLC/rack through RSLogix5000. As this happened over the weekend, the local electrician was called and he tried cycling power to the rack and there was no change after it came back on (not sure how long he left power off to the rack though). The problem seemed to be fixed after we told him to pull the EN2T card out of its slot and then re-insert it.We verified the CIP cinnections for this card and it is around 98 to 101 CIP connections out of a max of 248, so not too high. the card's CPU usage is 24-29%, so no indication of problems there. EN2T Card is set to auto-negociate, just like all the other cards we use at all of our plants. Has anyone ever experienced a similar problem?Thank you in advance for all your help and knowledge-sharing! -

Hello, i have DOP-07s411 delta hmi and i want to interface it with microcontroller using modbus (RTU) protocol over RS485( 8 bit data,1 stop bit, parity none,19200 baud rate). i have good speed of communication if i do not use macros. But as i place background macro(background macro is only 4 lines ) it slow down and updates the display at every 3 seconds. i cant able to figure out what is the problem. I want to update display of HMI very fast.Please help me to troubleshoot the problem.

Configuring AB PanelView C600 Ethernet Comunication
Simmi posted a topic in Allen Bradley / Rockwell Automation
Hello, I am hoping I can get some assistance configuring an Allen Bradley PanelView C600 (2711C-T6C). All a long I have been able to communicate with the HMI using Ethernet protocol, but after I switched communication settings to what my Professor recommended by using the Panelview software, the Ethernet connection seems to have stopped working. The HMI has now been reset to the factory settings (by pressing ctrl + shift during start up then selecting F1 when prompt appears asking if the user desires to return to factory condition of terminal). Once the terminal resets I am able to eventually get to the configuration screen. When in the communication settings Protocol says "*", Status says "Unavailable", I've changed the device name to "plc" and the Node Address says "0". When I click on the "Ethernet" option the IP mode says "DHCP" then the IP Address, Mask and Gateway all read "0.0.0.0". I get into CMD/DOS PROMPT on my laptop while the terminal is connected to my laptop via an Ethernet cable and type in "ipconfig" to see if my laptop is communicating with the terminal but it is not. The lights where the terminals are located are also not blinking. After plugging in several different Ethernet chords from the terminal to my laptop I am convinced the issue is not the cable. I've tried resetting the terminal several times as well and I'm having no luck. Can anyone assist me with regaining Ethernet communication with the terminal or some work-arounds? I see there is an option to use the USB but it looks like AB no longer provides the drivers on the website. If it helps, the manuals I am using are 2711C-UM001 and 2711C-QS001. -

Hi, I'm trying to test the serial communications with my Micro820. I acquired a 2080-SERIALISOL so I could have "someone" to talk to. I want to use RS485, so I figured that I'd have to connect: Modbus pin 1 (D+) to serialisol pin A1 (+485) Modbus pin 2 (D-) to serialisol pin B4 (-485) Modbus pin 3 (GND) to serialisol pin A2 (GND) Now when it comes to CCW, the thing gets a little harder. I know I need to use the MSG_MODBUS block (in fact I need 2, one for the modbus and another one for the serialisol), and I guess I specify the interface I'm using on the TargetCfg field (data type MODBUSTARPARA). But how do I figure out that the Addr (UDINT) and Node (USINT) values are for my Modbus and Serialisol? Or am I doing it wrong? Does anybody know of any place where I can get some more guidance or even a funcional ladder program? Thank you in advance

Wireless connectivity for Ultra 5000 IPD
Yashj7 posted a topic in Allen Bradley / Rockwell Automation
I have the Ultra 5000 Intelligent Positioning Drive for lifting purpose. Now currently the only way i am able to go online with the drive is through the Serial Communication cable (db9) and till the time i am online with the drive the movement of the lifting operation has to be put on hold. So is the anyway possible to go online with the ultra5000 drive on the wireless network? need some suggestion on accessing the drive parameters over wireless network instead of conventional serial communication cable. Thanks -

Hello, I am a newbie to the Omron world. We have a new machine come in made on Omron PLC, we are trying to get it connected to our OPC server so that the server can read and write tags via ther Ethernet/IP protocol. We have given out ethernet card 10.14.9.187 IP and the NJ501-1300 controller is on 192.168.250.1. But still our OPC server cannot see the tags/variables. I dunno if we have to add the ethernet communication card to the network configurator and add the tag sets ? We are also getting a tag resolution error on sysmac studio while being online. Thanks Pratik

Joshua Alf posted a topic in Allen Bradley / Rockwell Automation
HI , I would like to ask you for your opinion THIS IS MY PROBLEM WITH THE kinetix 6500 The equipment was working fine , but now i cant make to servo move with the program, cant run the test or autotuning Status in front of servo drives say running. Everything is green, no errors, when I activate the MSO I can hear a click at servodrive, but the servo is not energized, because i dont hear the usual noise when the servo is energized, I have check the cables and conectors, everythig is fines, I check the servo resistence , no shortcuts or open lines, The wierd part is when the servos are in the running state i can move by hand, they are supossed to be locked. after that I activate the home MAH, or test or autotuning , or a direct command ,and then it fails When i try to jog . move, test or autotuning the servo it says s55 velocity error or excess positon error, i can not get servo to move at all I can see the position from the encoder back to the plc. I have turned the servo and i see the position at actualposition Before the equipment was working , moving , I just swith it off one day, and the next day I couldnt make it move Best regards I have added the programm as an attachment k6500.ACD -

Upload from Quantum Hot Standby CPU 140 CPU 67160
waqas posted a topic in Modicon / Telemecanique / Schneider Electric
Gentlemen, I am beginner in field of PLCs and I need some help to create backup of project / program running on PLCs installed at our project. We have a Quantum Hot Standby PLCs ( 140 CPU 67160) installed at our water treatment plant; we connect to PLC via ethernet (TCP/IP) and I am preparing backup of these installed PLCs as vendor did not give us backup project files and provided little useful documentation. The problem is that, I have transferred the project from all of the PLCs using UnityPro XL, but for one PLC, when I connect to it the "transfer from PLC" option is not available. I am hoping if someone could help me with that. -
