  1. 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.
  2. 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!
  3. Hi, i am start a aplication whith modbus for a simple comunication(read/write), some analogic imputs and outputs, whith, AB Micrologix 1500 LSP (1 com port Rs232) and whith a Omron PLC CP1L-L + CIF01 (rs232). I using CP1L like a master, but i try a lot of time and no read/ Write happens, just the recognition of Node (1) and the error code 88, no mather whith Function code i use. I use Modscan32 whith Micrologix 1500 and works fine, com settings are right to, i try 38k, 19,2k, and now 9,2k None stop bit 1, setting on CP1L are in serial Gateway. If i take the cable the reponse memory go to zero, so the communication is happen, just dont in right way. Is possible to use, RS232 whith CP1L, for Modbus communication right ? I already see PCMR code for modbus, but is to complex, for my aplication. No ofense. Someone can help me?

  6. 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

  7. 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!
  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. Serie L and Modbus TCP

    pedro_pqc posted a topic in Mitsubishi

    Hi, We have to use a modbus tcp in orden to configurate several festo motor controllers via modbus tcp, We are going to use an L02P CPU because mitsubishi says modbus tcp protocol is implemented in its ethernet port. With FX3u we can use the function ADPRW, Is there any special function in serie L por modbus tpc? thanks in advance. pd: Any experience with MODBUS TCP with a GOT14?
  10. 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.

  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. Good day I have a scenario where I need to connect to Ethernet ST-lite units to an L-series PLC. With a Q-series you will use the Modbus card and create a Intellgent Function Module to do this and specify the header addressing for the unit. With the L-series, you have Modbus on the build-in Ethernet port, but how do I now setup and specify the addressing for the for the ST-lite unit? Please help...
  14. On Ethernet/Modbus-TCP, if a device is a Master, can it get polled by another Master? i.e. Can it act as a slave as well. Thanks, Arun

  15. 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 ?
  16. Is possible to comunicate an Eaton/Cutler Hammer INCOM/IMPACC network with a Modbus network ? Any experience ? Many thanks in advance.
  17. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.

  21. 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

    There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>(

  25. 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?
