  1. Horner XL4

    Greetings, I'm having trouble with a Horner XL4 power cycling itself when 120 V is switched with its relay outputs. I have tried both polarities and slowing down the switching quite a bit. The unit appears to power cycle even when the relay is not switching, and only when 120 V is applied to the relay outputs. I am driving a control 24 - 230 V AC/DC light off an on once a second or so, with the identified/neutral attached to the 120 V AC / 12 V DC PSU. Would anyone be able to guide me into what could be causing this? Thank you.

  4. Wireless Communication

    Hello All,      I just had a brain storm while I was setting up a new piece of equipment. As most of us who setup new equipment, we use a long, long, long Ethernet cable when we are trying to reach the end of the machine. I was wondering if anyone has used a portable wireless router instead of a cable. I carry a Cisco router currently, but it isn't very portable. I also thought about Bluetooth, but not sure the range and/or if it works.      Any thoughts on products? The big key is portability for me.
  5. Hi all. Long time reader, first time poster. I am tasked to make a couple of module specific function blocks for communication between our Mitsubishi PLC (GX IEC Developer 7.04) and a B&R remote IO over Profibus. A number of these blocks would then be used, depending on the RIO setup. Reading should be straight forward, just read X amount of words, starting from address Y. Writing is trickier as Mitsubishi prefers 16/32 bit Data whereas B&R batches Data in bytes! As I have several output modules in the RIO. I need to send my info "chained" together. Example: Module 1: 2 Bytes Module 2: 3 Bytes Module 3: 2 Bytes Totals: 7 bytes or 4 words. Sending the first word is no problem. Neither is the next two words (I will just have 1 empty byte at the end of the third word). But then the info to the third module should start in the middle of the third word. Any idea how I could solve this? Experimental: At the moment the blocks have inputs (bits), which are stored to a bit-array inside the block and then linked to an output. My idea at the moment is to merge all module-wise output bit arrays to one big bit array, converting that to INT and sending it off to the Profibus address. But I have not yet found a way to merge the arrays and shift them so all data is where it should be. Above example: ARRAY [0..15] OF BOOL + ARRAY [0..23] OF BOOL + ARRAY [0..15] OF BOOL Totals: ARRAY [0..63] OF BOOL or [0..71] counting the spare byte. Converted to 8 Words and forwarded through Profibus. Thank you in advance.
  6. Hello everybody, I want make communication PLC FX5U series and HMI GS2107-WTBD. IP for PLC is 192.168.3.250 IP for HMI is 192.168.3.18 I can make upload programs via Ethernet. My Laptop , PLC and HMI are connected toghether via switch. But I could connect data between PLC and HMI. So what must name of device and how to set BIT for example, which must communicate PLC<---->HMI. (bit.jpg) In GT Designer communication also write that i couldn't connect HMI via PLC in red , you can see attached picture. (GS.jpg) smiles : Altan ------------------------ Solved. My error was that PLC and HMI must have different Station Number Special thanks to Piotr Tynor(Mitsubishi, Poland ) , Adam Syrek (Mitsubish, Poland ) , I. Ayvazova (Bulgaria) , K.

  7. Modbus client problems with FX3U

    Hello, I have the following problem, I have two PLCs FX3U-16M, with a communication module FX3U-ENET-Port502 in both PLCs have built a server under Modbus TCP and a client to read the registers of the other PLC, my code of Modbus TCP client presents the error code C017 and errors in the channels for reading and writing the registers. Of course grateful for his help.
  8. 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!
  9. 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
  10. 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.
  11. 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!

    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
  13. CJ1M communication protocol

    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!
  14. Micrologix 1400 Problems

    I have been using a micrologix 1400 L32bxba. I have had a reoccurring problem of the contacts sticking on the processor. I have added diodes on the coils of the contactors. Using 700CB220EJ relays. I also have the problem of the leakage current being so high it pulls in the relays with the output off. Any help would be appreciated.
  15. 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,
  16. 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.
  17. 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
  18. 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.
  19. Control G120C via Profibus

    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 ?
  20. I have a question regarding hazardous zone design. My control cabinet will be in safe area but I need to have e-stop and safety limit switch located in hazardous area, Div 1 Zone 1. I am assuming that I can use zener barriers or isolators between the field devices and safety relay. I just wonder if the safety relay will function properly with barriers in between? Also do I have to use 24VDC safety relay for this application? I don't know what voltage/current is present on the terminals connecting to safety devices.

  23. 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
