  1. I need some help and advice communicating between an Omron PLC and a Keyence KV-5500. My system typically uses an Omron CJ2M-CPU34 which comes equipped with the built in Ethernet IP port.  My customer is insisting that we change the CPU in our system to a CJ2H-CPU66-EIP in order to communicate with the Keyence KV-5500.  They have not been able to detail why their communications require the CJ2H, they just say they will be using Ethernet TAG communication and for this they need us to change the CPU. Has anyone successfully established communicated between the Omron PLCs and the Keyence?  If so how did you do it and which CPU did you use?  Is there an .eds file available for the Keyence CPU? Please help!!! They will be visiting from halfway around the globe to test communications in January so I want to be prepared!

  2. FX1S-30MT Downloading of MAIN Program Failed

    freddy.salguero posted a topic in Mitsubishi

    I have a problem when trying to download a program from a FX1S-30MT PLC. I am using a SC-09 USB cable. The software i am using is GX Developer 8. When trying to download the MAIN program the screen in the attachment appears. I tested the download from another PLC of same model and have no problems, therefore the cable is ok, and the laptop is ok. When downloading of the parameters and comments does not give error, just when trying to download MAIN. Also I tested connection with Test Connection button and says communication is ok. Anyone who can help? I have a doubt, how can i see the communication parameters on the PLC side? Thanks a lot
  3. Using its internal Ethernet ports, our 1769-L36ERM processor communicates with 15 other devices inside the same machine. Can a rack mounted Ethernet module be installed to allow communication to/from this processor and an external network containing a SCADA system and RSLogix 5000 workstations? We prefer not to add all 16 devices to our external network and our I/S department does not allow routing devices on the network that they did not install.
  4. Hello I'm looking for a way to setup communication between a PC and a PLC. The PLC is an Allen Bradley compactlogix L30ER i would like to use the existing network which is a Ethernet setup. I've read and tried some OPC/DDE sample project with Excel and I'm wondering if there is a better way to do it. Thanks!

  5. connecting ixt4a to a cj1m/cp1l/ns network

    geomariolis posted a topic in Omron

    hi everybody i have a network with 2 pieces cj1m and 2 pieces cp1l communicating with a ns15 monitor. everything is fine. i need to connect an ixt4a monitor in that network. my question is : do i have to make new routing tables or it is not neccessary? my routing table for cj1m and cp1l cpus are attached. if then i have to make new routing table so that the cj1m will be able to communicate ixt4a monitor, how am i going to do it for both monitors? Any help will be mostly valuable and appreciated. thanks

  6. CJ1M communication protocol

    WKla posted a topic in Omron

    Hello, I am not familiar with the Omron PLC's. A PC is connected to the peripheral port of an CJ1M CPU12 PLC. The write command the PC is transmitting to the PLC looks like this (ASCII): "@00WD0070010055*." Can you tell me what kind of communication protocol it is using? It is a public or proprietary protocol? Thank you!
  7. I've got a PLC stack with a Q64AD analog-digital converter card. I am attempting to read the digital output value of channel 1 but I am having issues. First of all here is my simple PLC program: I got the program from the Q64AD user manual. You can see there is a blue '0' on the right of line 0. I assume this is the value that is being read? When I monitor the D11 device in GX Developer it shows a '0'. The following is a screen from Online > Monitor > Buffer memory batch. My card has a base address of 0x60 and channel 1's offset is 11d (0Bh). The value on the highlighted line does change so I know that the analog card is correctly picking up on current changes from my source. Lastly here is an image of my digital inputs. I have set up the Q64AD card through the GX Developer PLC Parameter window and left all settings as default. I initially used 'K11' instead of 'H0B'. I have also tried using the MOV command (MOV U0\G61 D11) but that game me the same result. Can anyone spot the flaw in my program of configuration? Do I need to configure the PLC in order to use the 'D' devices? Should I try copying the value somewhere other than D11? Thanks
  8. Hello, I am trying to communicate with MicroLogix 1100 from CompactLogix. But I keep getting an error and It says connection failure. This is what I have done so far. Can anyone tell me what I am missing? Regards,
  9. Hello everyone, I need to modify furnace ladder diagram to take control of the upper PID limit. The temperature on the furnace is controlled using PID. There is master PLC CJ1GCPU45SP which communicates several slaves CJ1MCPU13. It looks that all the PID parameters are send from the master to slaves over DeviceNet using seven DRM21 modules installed on extension rack. I can see where the values for the PID are entered on the HMI and moved to new location in the master but I don't understand why they are not placed in memory locations used by DeviceNet by default as per DRM-21 manual ( which if I understand correctly are D30000 to D31599). Is it because the DRM21 are mounted on extension rack? I will list all the upper limit locations in master, it is a long list but hopefully will help in resolving this issue: HMI entry location Moved to location in the ladder D16401 __________________ D32023 D16403 __________________ D32047 D16405 __________________ D32071 D16407 __________________ D32095 D16409 __________________ D32323 D16411 __________________ D32347 D16413 __________________ D32371 D16415 __________________ D32395 D16417 __________________ D32623 D16419 __________________ D32647 D16421 __________________ D32671 D16423 __________________ D32695 D16425 __________________ D29923 D16427 __________________ D29947 D16428 __________________ D31723 D16429 __________________ D31756 D16430 __________________ D31757 D16431 __________________ D31758 After they are moved to the D3xxxx location they are not used anymore anywhere in the master PLC so I am assuming they are transmitted over to be used in slaves. Is my reasoning correct? How can I calculate address space used by each DRM-21 card to make sure I am understanding what is transferred where? Thank you.
  10. I am trying to determine or find any figures that could assist in obtaining the lifespan of a single output of a 1756-OB16E output card. I have a signal sending 400 pulses a minute to an output. I am starting think about when this card or output may need to be replaced before failure. I was given a MTBF range by Rockwell for the card itself but they could not expand on the likelyhood of the output failing exponentially due to the rapid signalling. I could also not find anything in the manual itself that could provide me with an idea of longevity, I could be missing it? Also with this project I experienced something odd with the originally scoped hardware, a solid state 24VDC relay (700-HLS1.) By measuring the resistance I was able to see that the relay should have been opening and closing but the signal was not being received. So, I swapped the solid state relay for a mechanical relay and it worked fine. I was curious if the leakage could have an effect on this. The problem with the mechanical relay is that the life is dramatically reduced to about a month for this installation, life for the relay is shown at about 10,000,000 actuations. I was hoping to have this working with a little longer life expectancy. If anyone has any experience / tips / or suggestions it would be much appreciated! PG

  11. Built-in Ethernet vs QJ71E71 Module

    valsidalv posted a topic in Mitsubishi

    This is my company's first time using a Mitsubishi PLC and our partners/clients advised us against using the built-in Ethernet port on the Q03UDE CPU, saying that we should instead use a standalone QJ71E71 Ethernet module. The QJ71E71 costs 1.5x the CPU module so there are significant savings in using the built-in Ethernet. They cited reliability issues but can anyone here back up their claim? We use our PLCs as simple I/O blocks - a PC runs a program which communicates with the PLC and tells it what outputs to fire. There is no actual ladder logic on the PLC. The PC connects directly to the PLC. I wrote a small C# utility that blasts the QX40 and QY80 input/output cards on my stack with random values and reads them back to ensure correct data transfer. The QJ71E71 Ethernet module averages 10 ms for a read or write operation and the Q03UDE averages 3 or 4 ms (much quicker!). So, does anyone have a reason to use the QJ71E71 port instead of the CPU? Thanks
  12. Hello, I have an annoying problem with communication between Siemens S7 PLC and HMI panel. Here it how it looks like: I am using Siemens S7-315 with 343 Lean ethernet port. This port is used to communication with HMI terminal. Communication is realized through S7-TCP communication protocol. When I was testing the communication in the office everything worked fine and nothing wrong happened. The problem occururs only on the installation. After turning the PLC and HMI on everyting works fine, data is transferred correctly and variables are displyed on HMI. After a few hours the communication is suddenly lost. This is a direct connection between PLC and HMI and there are no other devices in this network. So it is not possible that suddenly there is an address confilct. I made a wireshark analysis (I connected a notebook and hub into the network) and I found out that when the communication is lost HMI terminal is trying to get data from the PLC but it is not responding. It looks like PLC ethernet port is broken. You cannot ping PLC from notebook and HMI. On the other hand you can exchange pings between HMI and notebook. The communication is back again only if you'll restart the PLC. The strangest thing is that I did not have any problem with the communication when I was testing it in the office. The configuration and project of PLC and HMI is excactly the same. The only difference is that on the installation PLC is realizing also a communication throguh Profibus and MPI. I've tried to use different ethernet cables (crossed, non-crossed) but in all cases the situation is the same. Do you know waht can be the cause of such behavoiur? Maybe someone had a similar situaion? In the attachment I send a screenshot from Wireshark which shows the moment when the communication breaks.

  13. Control G120C via Profibus

    Bryll posted a topic in Siemens

    I'm trying to control the speed of a G120C via profibus, but it will trip out when any changes are done to the speed value. The unit was commissioned by another guy, and he doesn't have a clue where to look. We can start and stop the unit, but it will stop at any attempt to change the speed. I was told to look for a parameter allowing it to be controlled remotely, but wich one is it ? As usual when it comes to Siemens, the manual sucks. I'm using a function block for controlling the drives (13), and the older 12 is responding correctly to any change. Anyone here that has a clue what parameter to change ?
  14. I'm new to Omron, and after several days of diving into manuals trying to figure this out on my own and giving myself a headache I've come to accept that i need help. my task is the following: Control of the discrete and analog inputs/outputs in a DeviceNet system using an Omron CJ1M PLC’s and PT’s. Use at least one thermocouple, one analog input, and one analog output for the DeviceNet network. Use a pushbutton and a light for the start of the process and an indicator for the started process. I have a Drt1-Ad04 input, a Drt1-ad02 output, and a Drt1-ts04t temperature control. My devicenet is Cj1w-drm21, The Omron system itself is a cj1m-cpu13 etn21. I have node addresses for my input, outputs and temperature control, those being 35 for input, 25 or 30 for output and for temperature control 5, 15, or 20. The ip address im using for this project is 142.214.143.9I'm using Cx programmer, Designer and Integrator. On Cx programmer I've managed to create an IO table but i have no idea on how to begin the program or even get a current reading from my generator.On Designer I've made what i believe to be the layout of the pushbuttons, I just have no idea of what addresses to enter.And on integrator i'm having troubles on figuring out how to make a routing table. I've went through many manuals and either i'm missing something really basic here or I just have no idea on what I'm doing. The only advice I was given was to dive into more manuals and find my addresses for my inputs, outputs, and temperature or to find the information from an outside source be that a forum or customer service. I am able to provide more information, and screenshots of what I have done if needed. Any kind of help would be greatly appreciated!

  15. CQM1-CPU43 Output OFF Bit SR 252.15

    sashaleiz posted a topic in Omron

    I am from AB world, but now am facing up with Omron PLC troubleshooting. One of my machines with Omron CQM1-CPU43 went out of work, because of low batteries in the PLC, program was lost and PLC stock with Error” Low battery” Is my luck, program was stored on EEPROM card, so I replaced the battery and reload program back to PLC, but after that other light on PLC comes up ”Output Inhibit Bit” is ON and all outputs are OFF. Operational manual sated just “turn back to OFF position, the “Output OFF Bit SR 252.15” and nothing else, where and how I can do it. I can not find in the CX programmer software the way to switch this bit, neither one rung in the program consist this bit, I really don’t know how solve this problem. Could you, please advice?

  18. Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance

    AlexCyril posted a topic in CX-Programmer

    Hello guys, actually I am new to this Omron PLC. but i have small project to transmit a command to the GSM modem via the RS232 port so it can trigger the modem to send text msg. Can you show me the steps/guide/sample program to accomplish this program coding? I already read some topic in this forum regarding to this PLC RS232 port but still cant get the ideas when to create the ladder program. PLC Type : CJ1H (CPU65H) - RS232 port First input to trigger the GSM send text msg: AT+CMGS="+YOUR HP NUMBER" Second input to trigger GSM send text msg: YOUR TEXT MSG CONTAINS (Ctrl+z to send) Many Thanks, AlexB
  20. Hi. I have a ST-Lite Ethernet base (STL-ETH1) with 1 16 bit digital in card, 3 digital out cards, 2 analog in and 2 analog out cards. I have a Q03UDE CPU (Q PLC) with 1 16bit digital in and 1 digital out card. Now I like to setup the remote I/O (STL-ETH1) mapped to the Q PLC via the ethernet port on the CPU. Is it possible not to use Modbus at all. I don't want to go and buy a Modbus Ethernet card now. Have someone done this before?
  21. I am working on Remote IO panel and plan to use the following components: 1734-AENT 1734-OW4 - qty 2 1734-IE4C I wonder if I need to separate the bus between the relay output module and analog input module? Or anywhere else in this setup? Thanks.
  22. I have had a GE 90-30 CPU331 in my house for 17 years with no trouble at all. I have a problem that I have never seen before. I was editing the program using LM90. I don't know what I could have done in the program to disable an output. Just 1. All the rest of the points in that group on that card still work. I swapped cards with no difference. All of the elements of the rung are true (highlighted). The output is not on or highlighted. The nickname over the output has ONE letter highlighted. The bit in the reference is "0" and is highlighted or "grayed out" (the cursor is not on it). I searched for coil conflicts. I am using this output contact lots of places but only one output. The logic is working correctly when I use another output or %M. This is an isolated output which needs to be in this group (moving it would be awkward). What does a "grayed out" reference bit mean?
  23. I have 4 Allen Bradley PLCs which are 3 SLCs and 1 CLX This PLCs need to send data to Yokogawa Centum VP DCS. Instead of having and individual Modbus link to DCS, I'm planning to link all 4 PLCs by using Ethernet/IP and plan to buy 1 extra mini PLC which is Micrologix 1400 to become an interface PLC between the 4 PLCs and the DCS. Since the Micrologix 1400 has embedded with an Ethernet port (Ethernet/IP) and Rs485 port for Modbus RTU, the Micrologix 1400 interface PLC will communicate with DCS using Modbus RTU Protocol. Meaning to say, the 4 PLCS will send data to the Yokogawa DCS via interface PLC. The Interface PLC will become translator to translate from Ethernet/IP language to Modbus RTU language. My question to Expert: 1. Is this setup can works? 2. How to send data inter-PLC by using Ethernet /ip ? Is it just need to grab the tagname or there is an address for that? 3.Is Micrologix is capable to communicate with 4 PLCs using Ethernet/IP? Or just only 1 PLC? See the attached photo. Thanks. -Nizam-

  24. FX3U_GXWORKS2_BINARYCODE_BY_OUTPUTS

    UltraSound posted a topic in Mitsubishi

    Hi all, Im new with plc programming and now I need some help. As topic says, I have FX3U plc and gx works2. Now, I need to tell stack heigth as positions by output. We all agree, that you can tell ten different situations when you have four outputs (Y1 and Y4 = position five). Is there any practical/ reasonable way to do this when you need use outputs. For example, is there any Functions for this, or? Best regards Ultra.
